ANALYTICAL REAGENTS (AR)

Reagents useful for analytical purpose and research

work where high purity is essential. The certificate

of analysis gives the minimum assay and maximum

limits of trace impurities.

ACS

The correct grade for Analytical laboratory applications.

Specifications meet the American Chemical Society

Standards.

FOR SYNTHESIS

General purpose reagents used in many potential

applications in chemical laboratories & applications

for organic chemistry. Careful control ensures that

a consistently high defined quality is maintained

throughout.

EXTRA PURE (EP)

Laboratory reagents which are extra pure or purified

are used in many chemical laboratories & technical

production applications.

HPLC GRADE

Highest purity solvents having features such as UV

absorbance, transmittance, non-volati le matter,

moisture content, fluorescence impurities and assay

are very carefully controlled. Continuing advances

in the use of HPLC have led to an increased demand

for solvents and reagents in wider range of application

areas, particularly for bimolecular and ion separation.

GC GRADE

Solvents which are extremely high-purified. To

guarantee our tight specifications we perform strict

GC quality controls. After strong concentration of

the solvent, differences in quality are easily revealed.

As more sensitive capillary GC methods are

introduced, solvent purity must be improved to meet

the more stringent analytical requirements. According

to this, GC Grade solvents have evolved.

SPECTROSCOPY GRADE

These are solvents of high optical purity for UV/

Visible/IR/Fluorescence/NMR and Mass spectroscopy.

The certificate of analysis includes assay, minimum

transmission at certain defined wavelengths in UV

range, moisture content, non-volatile matter etc.

DIAGNOSTIC REAGENTS

These are specially produced for the use of various

hospitals, clinical and pathological laboratories for

diagnostic purpose.

BIOLOGICAL STAINS

Stains are frequently used in biology and medicine to

highlight structures in biological tissues,Histology,

Hematology and Cytology. Stringent testing on all

batches is performed to ensure all specifications

are satisfied. They correspond normally to the

specifications given in the handbook on Biological

Stains titled “Stains and staining (Microscopy)” .

BIOCHEMICALS

Highly purified reagents for use in biochemical

research and analysis. They are free from inhibitors

such as traces of heavy metals and tested with a

view of biochemical work. Our range includes alkaloids

amino acids, buffers, carbohydrates, enzymes, enzyme

substrates, nucleotides, derivatives etc.

MOLECULAR BIOLOGY GRADE (MB)

To meet the requirements of our Molecular Biology

customers in the Life Sciences Sector we are expanding

our Molecular Biology performance grade product

line. These products are prepared specifically for

Molecular Biology usage and are certified to be

DNase, RNase, for detecting DNA-protein, RNA

enzymes and protease-free.

ION PAIR CHROMATOGRAPHY

Highly pure additives for ion pair chromatography

are suitable for detection in the low UV range.

Reagents of this special quality inspected by means

of a filter test, a cyclovoltagram and gradient test

at 205 nm in the Spectral Band.

Risk & Safety Phrases are guidelines for labeling various types of dangerous chemicals to ensure their safe use and most

importantly, the well-being of the persons using them.

These phrases are made to convey a description of the chemical, environmental and health hazards of a product/substance, whereas the

safety phrases provide information on safe storage, handling, disposal, first-aid and employee protection.

Risk & Safety information is given if the product contains at least one substance classified as dangerous to human or the environment or if

the product is otherwise generally termed dangerous.

TIRUPATI’s GUARANTEE
