Dear Customers,

Best regards,

Warm greetings for the new financial year. It is always my great pleasure to present to styou Borosils latest pricelist, which becomes effective from 1 April, 2010.

This year is set to be another exciting one from the point of view of Indian industry. The financial turmoil which swept the world last year seems to have given impetus to Indian industry, as we see more and more companies investing in production and R&D facilities in India. India is increasingly being seen as a place where companies can draw value not only by setting up back offices, but also as a place where new product development and cutting edge research can be undertaken.

At Borosil, we have been anticipating and gearing up for this change for the past few years. Our new production facilities have the ability to deliver high quality glassware in sizeable quantities. For this purpose, we have made further investments in automation and new technologies for glass handling. Our investment in SAP has helped us improve levels of customer service and our introduction of a range of high quality liquid handling systems has been appreciated by you.

This year, we are proud to announce the introduction of a new range of tissue culture products. These products find usage in biotech and microbiology, both growth areas in the Indian context.

In addition to this, there are a number of other glassware product introductions that are individually highlighted in the catalogue.

For any comments or feedback on how we could serve you better, please feel free to contact me on [email protected].

I take this opportunity to wish all of you the very best for the year ahead.

AUTO CALIBRATION MACHINE

an ISO 9001 certified company 3

Calibration ProcessBorosil performs the calibration process with fully automatic state of art calibration machines that remove any possibility of human error and ensure a high degree of repeatable measurements for all our volumetric products.

Borosil has an in house set up of a well-equipped temperature controlled calibration laboratory with precision electronic balances, thermometers and stopwatches that are traceable to national standards. Only experienced & trained technicians are used for calibration of volumetric glassware.

The following steps are carried out by highly precise fully automated computer controlled machines:

1. Filling the volumetric blanks with precisely defined amount of de-mineralized water under a controlled temperature.

2. The meniscus is determined with a laser controlled camera at the exact lowest point of the water level and the calibration mark is made with a fine diamond wheel. This gives accuracies that can never be achieved by manual calibration.

3. Cylinders, Burettes and pipettes are marked at minimum two calibration points.

4. The wet surface area factor is always taken account throughout the process.

5. The calibration laboratory is temperature and light controlled and the nominal calibration temperature is 27.0 C.

All volumetric glassware is calibrated either as; To contain Tc, In or To deliver TD, Ex.

These steps ensure that each and every volumetric product leaving our facility matches the best international standards and can be used for all purposes with the highest degree of repeatability and accuracy

Borosil is the single largest manufacturer of the complete range of volumetric glassware in the country. Our volumetric products find usage in all laboratories from high-end pharmaceutical production to high schools and colleges.

Borosil adheres to the tightest quality standards right from the usage of the raw material to the measurement and calibration of the finished product. Visual & physical quality checks are performed at each stage of production so as to ensure the highest quality product for our customers.

Borosil ensures each of its volumetric ware is of the highest quality in the following parameters:

1. Accuracy: Please see 'calibration process' for a detailed understanding of how Borosil volumetric ware is the most accurate in the world

2. Mechanical Strength: All Borosil laboratory glassware products are annealed in a special chamber wherein the stress developed during the manufacturing process is eliminated under a controlled heating & cooling process. Moreover, our production processes ensure uniform wall thickness across all our products, thereby enhancing mechanical strength.

3. Thermal Shock Resistance: The annealing process further ensures that our products are free of residual stresses. Moreover, the uniform wall thickness of our products ensures that our products are not damaged owing to repeated heating and cooling in laboratories

4. Chemical Durability: All Borosil laboratory glassware products are manufactured using 3.3 low expansion ASTM E-438 Type 1 Class A borosilicate glass. This glassware, by nature, is resistant to attack from acids, salt solutions and organic solvents.

HPLC, as an analytical tool for detection and separation of chemical compounds, has become the most important laboratory technique over the last decade. As with all analytical techniques, minor processing problems sometimes appear which in the long run can have major impact on the accuracy of the system as well as its durability.

Filtration of solvents prior to analysis is recommended by most instrument manufacturers. Particulate matter in solvents can cause damage to expensive pumps, clog analytical columns, and in general cause wear and tear to the instruments. Particulate matter and dissolved gasses in solvents can also create spurious peaks or can result in baseline instability. HPLC grade solvents, even though filtered prior to shipment by the manufacturer, can accumulate particles during storage due to shedding from the solvent containers and solvent condensation.

The use of salts and buffers can also significantly contribute to particles in the mobile phase.

Filtration solvents reduces instrument down-time, prolongs the life of the analytical columns, pumps and valves and most importantly helps the instrument perform in optimal fashion.

Chemical Durabilityis highly resistant to water, neutral and acid solutions,

concentrated acids and their mixtures as well as to chlorine, bromine, iodine and organic matters. Even during extended

0period of reaction and at temperatures above 100 C, its chemical resistance exceeds that of most metals and other materials. It can withstand repeated dry and wet sterilization without surface deterioration and subsequent contamination. Resistance to attack of various chemicals is shown below. Only hydrofluoric acid, very hot phosphoric acid and alkaline solutions increasingly attack the glass surface with rising concentration and temperature.

Due to low expansion of glass and easy workability, this glass can be shaped, formed, joined into complicated apparatus. It can be done even by an analyst in his own laboratory and keep on changing till he gets what he needs. In case where annealing in a controlled oven is difficult he can do so by flame annealing which is also a great advantage.

thFrom the 16 Century to today, chemical research teams have used glass containers for a very basic reason : the glass container is transparent, almost invisible. And so the contents and the reaction are clearly visible. But because chemists must heat, cool and mix chemical substances, ordinary glass is not always adequate for laboratory work.

Laboratory work requires apparatus made in a glass which can readily be moulded into any desired shape or form, which offers maximum inertness when in contact with the widest range of chemical substances, which can withstand thermal shock without fracture and high temperature work without deforming, and which will be resilient enough to survive the everyday knocks to which it will be subjected in normal laboratory handling, washing and sterilizing processes.

is the trade name of such a glass.

Items represent optimum mechanical, thermal and chemical behaviour. This glass is used in laboratories as well as for industrial applications where maximum thermal resistance, thermal shock resistance, mechanical resistance as well as unusual chemical resistance are required.

Thermal Properties

Chemical Composition

glass is a low alkali borosilicate Type 3.3 glass. Its typical chemical composition is given below. It is virtually free of magnesia-lime-Zinc group and is completely free of arsenic and other heavy material.

Approx % by weightSiO 812B O 132 3Na O / K O 42 2Al O 22 3

As the Coefficient of thermal expansion of glass is low, the thermal stresses under a given temperature gradient are consequently low and the glass can withstand higher temperature gradients and also sudden temperature changes / thermal shocks. Minute scratching of glass surface can however reduce its thermal resistance.

In general Strain Point should be regarded as the maximumsafe operating temperature of glassware. When

0heated above 500 C the glass may acquire permanent stresses on cooling.

Thick walled glassware should not be subjected to direct flame or other localised heat source. Vessels of this type are best heated with the use of an electric immersion heater.Avoid heating glassware over electric heaters with open elements. Uneven heat of this type can induce localised stress and increase the chances of breakage.Remember that a hot plate will retain heat long after the appliance has been switched off.Always ensure that the surface of the hot plate is larger in area than the base of the vessel being heated. An under-sized plate for the job in hand will invite uneven heating and promote breakage of glassware.Always ensure that manufacturers instructions are followed when using electrical heat sources.

Mixing And Stirringv

v

v

v

Always use a policeman or similar device on stirring rods to prevent scratching of the inside of a vessel.When using a glass vessel with a magnetic stirrer always use a covered follower to prevent abrasion of the inside of the vessel.When using glass or metal mechanical stirrer in a glass vessel always predetermine the height of the stirrer before use to ensure there is no contact between the stirrer blade and the bottom or sides of the vessel.Never mix sulphuric acid and water inside a glass measuring cylinder. The heat of reaction can break the base of the cylinder.

Vacuum And Presurev

v

v

Never use a glassware beyond the recommended safe limit.

Always use a safety screen when working with glasswaresubjected to pressure or vacuum.Never subject glassware to sudden pressure changes. Always apply and release positive and negative pressures gradually.

Care And Maintenance

Heating And CoolingGlass may suffer damage in three ways.

It may break under thermal stress in the steady state, that is when a constant thermal gradient is established through the glass.It may break under the transient stress of a thermal shock, that is sudden heating or cooling.It may, if heated beyond certain temperature, acquire a permanent stress which on cooling could cause subsequent failure.

The following precautions will assist in avoiding failures during heating and cooling procedures.

Never leave vessel unattended when evaporation work is being carried out. The vessel may crack or explode as dryness condition approaches and if the heat source is not adjusted correctly. Lower the temperature gradually as the liquid level drops.Always use caution when removing glassware from a heat source and avoid placing on a cold or damp surface.Although the ware can withstand extreme temperatures, sudden temperature changes may cause the vessel to break.Always cool vessels slowly to prevent thermal breakage.Never apply heat to badly scratched or etched vessel as the thermal strength would have been greatly reduced.Never apply point source heating to a vessel as this will greatly increase the chance of breakage.Always diffuse the heat source by using a metal gauze or air/water bath. Alternatively ensure even heating of the vessel by slow movement of the vessel in relation to the heat source.Adjust bunsen burner to get a large soft flame. It will heat slowly but also more uniformly. Uniform heat is critical factor for some chemical reactions.Ensure that the flame contacts the vessel below the liquid level. Heating above that level will invite breakage of the vessels.Always use anti-bumping devices in the vessel, such as powdered pumice or glass wool when rapid heating of the vessel and contents is required.Never use material with sharp edges such as broken porcelain as an antibumping device. This will cause internal abrasions and reduce the mechanical and thermal strength of the vessel.

When storing glass stopcocks and joints, insert a thin strip of paper between joint surfaces to prevent sticking.

Never store stopcocks for long periods with lubricants still on the ground surfaces.

Glass stopcocks on Burettes and Separating Funnels should be lubricated frequently to prevent sticking.

If a ground joint sticks, separations can generally be achieved by carefully rocking the cone in the socket, or gentle tapping the socket flange on a wooden surface, or by heating the socket and not the cone in a localised flame. The use of penetrating oil will often prove useful in aiding separation.

In using lubricants it is advisable to apply a light coat of grease completely around the upper part of the joint. Use only a small amount and avoid greasing that part of the joint which contacts the inner part of the apparatus.

Three types of lubricants are commonly used on standard taper joints.

(a) Hydrocarbon grease is the most widely used. It can be easily removed by most laboratory solvents, including acetone.

(b) Because hydrocarbon grease is so easily removable, silicon grease is often preferred for higher temperature or high vacuum applications. It can be removed readily with chloroform.

(c) For long term reflux or extraction reactions, a water soluble, organic and insoluble grease, such as glycerin, is suitable. Water will clean glycerin.

There are other types of greases which can be used specifically when certain reagents are used in the Burettes or Separating Funnels.Details of these can be available from our nearest Regional Sales Offices.

The use of water, oil or glycerol is recommended on both tubing and rubber bung when inserting glass tubing into a bung. Always wear heavy protective gloves or similar protection when carrying out this operation.

Always fire polish rough ends of glass tubing before attempting to insert into flexible tubing. The lubricants recommended above may also prove useful.

Never attempt to pull a thermometer out of a rubber bung, always cut the bung away.

Use tongs or asbestos gloves to remove all glassware from heat. Hot glass can cause severe burns.Protective gloves, safety shoes, aprons, and goggles should be worn as safety against chemical accidents, spilling or splattering.Always flush the outside of Acid bottle with water before opening. Do not put the stopper on the counter top where someone else may come in contact with acid residue.Special care is needed when dealing with mercury. Even a small amount of mercury in the bottom of a drawer can poison the room atmosphere. Mercury toxicity is cumulative and the elements ability to amalgamate with a number of metals is well known. After an accident involving mercury, the area should be gone over carefully until there are no globules remaining. All mercury containers should be kept well stoppered.Never drink from a beaker. A beaker left specifically for drinking is a menace to the laboratory. Do not tastechemicals for identification. Smell chemicals only when necessary and only by wafting a small amount of vapour towards the nose.Avoid pipeting by mouth, particularly when using concentrated acids, alkalis or potentially biohazardous materials. Use mechanical means such as a rubber bulb or a automatic dispenser.Never fill receptacle with material other than that called for by the label. Label all containers before filling. Throw away contents of unlabelled containers.To avoid breakage when clamping glassware, do not permit glass-to-metal contact, and do no use excessive force to tighten the clamps.Do not look down into a test tube being heated or containing chemicals, and do not point its open end at another person. A reaction might cause the contents to be ejected, resulting in injury.Splattering from acids, caustic materials and strong oxidizing solutions on the skin or clothing should be washed off immediately with large quantities of water.When working with chlorine, hydrogen sulphide, carbon monoxide, hydrogen cyanide and other very toxic substances, always use a protective mask or perform these experiments under a fume hood in a well ventilated area.In working with volatile materials, remember that heat causes expansion and confinement of expansion results in explosion. Remember also that danger exists even though external heat is not applied.Perchloric acid is especially dangerous because it explodes on contact with organic materials. Do not use perchloric acid around wooden benches or tables.Keep perchloric acid bottles on glass or ceramic trays having enough volume to hold all the acid in case the bottle breaks.When using perchloric acid, always wear protective clothing. When using hot plates and other electrical equipments, ensure the wire and plugs are in good condition. Never handle electrical connection with damp hands.


Cleaning

Successful experimental results can only be achieved by using a clean apparatus. In all instances laboratory glassware must be physically clean, in nearly all cases it must be chemically clean and in specific cases it must be bacteriologically clean or sterile. There must be no trace of grease and the safest criteria of cleanliness is the uniform wetting of the glass surface by

_distilled water this being of the utmost importance for glassware used for volumetric methods. Any prevention of uniform wetting of the surface will introduce errors such as distortion of the miniscus and accuracy of volume.

Cleaning of glassware which has contained hazardous materials must be solely undertaken by experienced personnel.Most new glassware is slightly alkaline in reaction. For precision chemical tests, new glassware should be soaked several hours in acid water (1%solution hydrochloric acid or nitric acid) before washingGlassware which is contaminated with blood clots, culture media, etc. must be sterilized before cleaning.If glassware becomes unduly clouded or dirty or contains coagulated organic matter, it must be cleaned with chromic acid cleaning solution. The dichromates, should be handled with extreme care because it is a powerful corrosive.Wash glassware as quickly as possible after use but if delays are unavoidable, the articles should be allowed to soak in water.Grease is removed by weak sodium carbonate solution or acetone or fat solvents. Never use strong alkalis.Hot water with recommended detergents should be used and if glass is exceptionally dirty, a cleaning powder with a mild abrasive action can be applied provided the surface is not scratched.During the washing, all parts of the article should be thoroughly scrubbed with a brush selected for the shape and size of the glassware. Brushes should always be in good condition to avoid any abrasion of the glassware.When chromic acid solution is used, the item may be rinsed with the cleaning solution or it may be filled and allowed to stand-the amount of time depending on amount of contamination on the glassware.Special types of precipitate material may require removal with nitric acid, aqua regia or fuming sulphuric acid. These are very corrosive substances and should be used only when required.It is imperative that all soap detergents and other cleaning fluids be removed from glassware before use. This is especially important with the detergents, slight traces of which will interfere with serologic and culture reactions. After cleaning, throughly rinse with tap water ensuring that containers are partly filled with water, shaken and emptied several times. Finally rinse with deionised or distilled water.Drying can be undertaken either in baskets or on pegs in air or

0at a temperature not exceeding 120 C.

Place pipettes tips down, in a cylinder or tall jar of water immediately after use. Do not drop them into the jar, since this may break or chip the tips and render the pipettes useless for accurate measurements. A pad of cotton or glass wool at the bottom of the jar will help to prevent breaking of the tips. Be certain that the water level is high enough to immerse the greater portion or all of each pipette. At a convenient time, the pipettes may then be drained and placed in a cylinder or jar of dissolved detergent or, if exceptionally dirty, in a jar of chromic acid cleaning solution. After soaking for several hours, or overnight, drain the pipettes and run tap water over and through them until all traces of dirt are removed. Soak the pipettes in distilled water for at least one hour. Remove from the distilled water, dry the outside with a cloth, shake out the water and dry.In laboratories where a large number of pipettes are used daily, it is convenient to use an automatic pipette washer. Polyethylene baskets and jars may be used for soaking and rinsing pipettes in chromic acid cleaning solution. Electrically heated metallic pipette driers are also available.After drying, place pipettes in a dust-free drawer. Wrap serological and bacteriological pipettes in paper or place in

0pipette cans and sterilize in the dry air sterilizer at 160 C for two hours. Pipette used for transferring infectious material should have a plug of cotton placed in the mouth end of the pipette before sterilising.

Remove stopcock key and wash the burette with detergent and water.Rinse with tap water until all the dirt is removed. Then rinse with distilled water and dry.Wash the stopcock key separately. Before the stopcock key is replaced in the burette, lubricate the joint with a small amount of lubricant. Remember that burette stopcock keys are not interchangeable.Always cover burettes when not in use.

vAlways Protect clean glassware from dust by use of temporary closures or by placing in a dustfree cabinet. For Cleaning Specific types of glassware, please refer below.


Culture Tubesv

v

v

Culture tubes which have been used previously must be sterilized before cleaning. The best general method for sterilising culture tubes is by autoclaving for 30 minutes at

0121 C (15 lb pressure). Media which solidify on cooling should be poured out while the tubes are hot. After the tubes are emptied, brush with detergent and water, rinse throughly with tap water, rinse with distilled water, place in a basket and dry.If tubes are to be filled with a medium which is sterilized by autoclaving, do not plug until the medium is added. Both medium and tubes are thus sterilized with one autoclaving.If the tubes are to be filled with a sterile medium or if they are to be sterilized by the fractional method sterilize the tubes in the autoclaves or dry air sterilizer before adding the medium.

Serological Tubesv

v

v

v

Serological Tubes should be chemically clean but need not be sterile. However, specimens of blood which are to be kept for some time at room temperature should be collected in a sterile container. It may be expedient to sterilize all tubes as routine.

To clean and sterilize tubes containing blood, discard the clots in a waste container and place the tubes in a large basket. Put the basket with others, in a large bucket or boiler. Cover with water, add a fair quantity of soft soap or detergent and boil for 30 minutes. Rinse the tubes and clean with brush, rinse and dry with the ususal precautions.It is imperative when washing serological glassware that all acid, alkali and detergent be completely removed. Both acid and alkali in small amounts destroy complement and in larger amounts produce hemolysis. Detergents interfere with serologic reactions.Serological tubes and glassware should be kept separate from all other glassware and used for nothing except serologic procedures.

Dishes And Culture Bottlesv

When you use a burette you expect accuracy, reliability and durability. Only brand burettes offer all three even after repeated usage. A combination of the best

material and workmanship goes into brand burettes. The highest quality accurate-bore tubing is selected to provide uniform and accurate graduations. Each burette is individually calibrated for precision and high accuracy. All graduations are in durable white enamel. The burette stopcocks are specially ground so that they provide a leak proof operation. It is advantageous to use different types of greases depending on the reagents used to get leak proof operations. Stop-cock plugs are solid pressed and ground. These are not interchangeable.In addition to Burettes with glass stop-cocks we have burettes with straight bore PTFE stopcocks and a range of Boroflo Burettes fitted with Boroflo(GP) screw thread stop-cocks with PTFE Keys.Boroflo Burettes are fitted with Boroflo GP(General Purpose) Screw thread Stopcocks with PTFE keys offering the following operational advantages -

_vLubrication never required no seizure, no contaminating greases._vExcellent flow control invaluable on burettes

vAll glass / PTFE pathway, highly resistant to chemical attack_vNo leakage unique Fluon / glass seal

_vNo springs or retaining devices easy to dismantle and clean_vNo ground surfaces low absorption of radioactivity

0 0vConsistent performance between 0 C and 50 C

For accurate work, Class A Burettes are available.

Glass Distillation Units continue to be the most effective, economic method of producing ultra pure water for laboratory use.

By contrast, De-ionisers are only effective in removing those substances which are ionized. Further the resins contribute organic impurities to water and an ideal environment for bacterial growth in course of time.

These distillation units are designed to produce a distillate of consistent purity. The unit consists of horizontal Borosilicate Boilers, Condensers and Quartz Heater. All parts are replaceable.

AdvantagesCompact, simple to use.

Economical and ideal for colleges and general laboratory use.

Powder coated stand for rust free operation.
