Varian Cary 100/300/400/500 Spectrophotometers

Carythe instrument for today & tommorrow

High performance, flexibility and ease-of-use are just some of the words that are associated with the Cary range of UV-Vis-NIR spectrophotometers. If you want to invest your money in an instrument that meets all of your needs today, as well as future requirements that you may not have even thought of yet, feel confident that a Cary is that instrument. The Cary range is extensive, with instruments to suit most budgets and applications. Cary 50* This innovative instrument represents the budget end of the Cary line. Cary 100 A low to mid-priced instrument, the Cary 100 is suitable for routine and research laboratory work. Cary 300 represents a cost effective, research-grade instrument for laboratories doing analyses of biological or highly absorbing samples. Cary 400 This research-grade instrument represents the top-of-the-line UV-Vis spectrophotometer. (Optional deep UV version also available.) Cary 500 extends the capabilities of the Cary 400 up to 3300 nm. If you want an instrument that will measure any sample then the Cary 500 is the best choice. Cary Eclipse Fluorescence* spectrophotometer compliments the Cary UV-Vis range by offering the first truly new mid-range fluorescence instrument in more than 10 years.2

CaryMore than 50 years of excellence

Fifty years of experience, starting with the Cary 11, serial number 2, circa 1947.

For investigators who on occasion must push a spectrophotometer to the very limits of its performance capability to obtain the information they need, and yet have to have an instrument which is adaptable to many different applicationsHoward Cary The Cary Philosophy 1947

Applied Physics Corporation (known later as Cary instruments) was founded in January, 1946, by Howard Cary, William W. Miller, George W. Downs, and Russell E. Vaniman. Howard Cary made important contributions to analytical instrumentation in the mid 1930s and early 1940s. He founded Cary instruments just after leaving his position as vicepresident in charge of development with Beckman Instruments, where he had been for 11 years. In April 1947 Applied Physics Corporation delivered the first commercial recording UV-Vis spectrophotometer, a Cary 11, to Mellon Institute in Pittsburgh, USA.

At that time Applied Physics Corp had only 12 employees. In 1954 the Cary family grew to include the Cary 14.

By that time the Cary name had become synonymous with high performance and reliability. In 1966 Cary merged into Varian and in 1972 the Cary operation moved from Monrovia to Varians main facilities in Palo Alto, California. In 1982 the Cary operation was moved to the Varian Techtron facility in Melbourne, Australia. During the mid to late 1980s the Melbourne based factory was very busy researching and developing a whole new generation of Cary instruments. Using the best optical and performance characteristics of the past Cary instruments and the latest technology in electronics and software the Cary 1, 3, 4 and 5 were created. On the 50th anniversary of the first Cary a whole new series of Cary instruments, the Cary 50, Cary 100, Cary 300, Cary 400 and Cary 500 were born. In 1999, the Cary range was extended to include the Cary Eclipse fluorescence spectrophotometer, offering the excellent specifications and modern software that has become the Cary standard.

Youre not just buying a Cary, youre buying a relationship But what if you need help with your Cary instrument? Thanks to the wonders of our electronic age there are many options and sources of information for you to access, including: Free access to other Cary users around the world via an Internet mailing list. If you have access to email then you can ask any question you like, for example, Has anyone measured this type of sample before? Your email will be automatically sent to all other Cary users who subscribe to the list. Experts at Varian also belong to this list, so you are assured of getting the answer you need. Varian also uses the mailing list to notify users of new products, new application notes and other useful information. You can call your Varian office and get over-the-phone support or request an on-site service call.

If you purchase the Tele-diagnostics option then Varian can test your instrument remotely to try and find the fault. This saves you money and gives you access to Varian expertsno matter where they are. Varians website contains many application notes. You can use these to find out how to measure a particular sample or how to optimize the use of your Cary. A visit to the website will also give you information on the latest software and hardware releases. If you need parts or supplies for your Cary then our website has an extensive list. If you arent connected to the Internet then you can receive the parts and supplies catalog on CD ROM.Varian on the Net Varian maintains a comprehensive website.

Cary 100 & 300

The Cary 300 has a premonochromator, extending its range past 5.0 Abs

A phase locked wavelength drive prevents peak shifts and peak suppression at high scan speeds

The sealed optics prevent exposure to corrosive environments

Variable slits provide optimum control over spectral resolution

Quartz overcoating protects the optics from the environment and allows cleaning without damage to their reflective surface

Although the Cary 100 and 300 are double beam design you can elect to operate them in single, double or dual-single beam modes

The Accessory Controller offers centralized accessory control. This makes it easier to service the instrument as there is only one set of accessory electronics. You can also communicate with non-Varian accessories via the Accessory Controller The large sample compartment gives you more flexibility in sample size

Double choppers ensure that the sample and reference beam strike the detector at the same point, removing any errors due to nonuniformity of the detector


The patented optical system eliminates residual chopper wobble, preventing any image movement on the detector

Cary 400 & 500

The lamp turret has provision for a third lamp of your choice. The turret can be completely removed if you wish to install another light source

The slits can be fixed in the NIR as well as the UV-Vis

The out-of-plane design of the double Littrow monochromator reduces photometric noise and stray light, and produces excellent resolution A floating solid aluminium casting isolates the optics from external disturbances

The Cary 400/500 wavelength drive can change wavelengths at 16 000 nm/min in the UV-Vis and at 64 000 nm/min in the NIR

The monochromator and sample compartments have separate nitrogen purging plumbing

Schwarzchild coupling optics ensure a high level of light throughput. This produces more accurate measurements at low transmission levels

The sample compartment windows are tilted to prevent back-reflection and thus incorrect results

The PbS detector is thermoelectrically cooled to 0 C to reduce photometric noise

A big sample compartment, with a removable floor plate, gives you maximum flexibility when mounting samples The optics are silica overcoated, so that they can be cleaned without damage to the reflective surface

Electronics are also a very important design consideration. The extended dynamic range of the Cary instruments is a result of this. The Cary 400 and 500 instruments for example, are specified to measure up to 7 Abs with reference beam attenuation


Cary Win UV softwarejust what you asked for

The Cary Win UV software has a modular design which means that you are only buying the functionality that you need. It also means that if your use of the spectrophotometer changes in the future it is simple to upgrade to meet your new requirements. Of course, the Cary Win UV software takes advantage of Windows 32-bit functionality such as multitasking and file association, for example you can drag and drop a data file onto a Cary application and it will be immediately loaded. Several Cary packages are available for the most common UV-Vis-NIR applications. These packages bundle together appropriate software modules with an instrument to suit each application. The three general use packages are Scan, Conc and Bio. Packages are also available for Tablet Dissolution, Color Analysis, Ultra-Violet Protection and the list is continuously growing. Of course, you can then add any of the Cary accessories that you need.
