Don't settle for an ordinary UV-Vis spectrophotometer... The most expensive mistake you'll ever make selecting a UV-Vis spectrophotometer could be spending too little. Especially in these days of budget squeeze and grant combination when you have to consider long range as well as short range needs. For just a few dollars more than you would pay for an average spectrophotometer you can have the high optical and photometric performance of the versatile Varian Cary 219. The 219 is by far the most sensitive and reproducible double-beam spectrophotometer ever offered in this price range. Performance features that give you extra capability include the following: Kinetics System—a five-sample, five-reference automatically timed sample changer. Routine Sampling System—an automatic sipper which can heat or cool 500 microliters of sample to 20° 25° 30° 32° and 37°C in less than fifteen seconds. It's also available in an unthermostatted version.
Wavelength Programmer —unparalleled positioning of selectable wavelengths. Temperature Readout— for absorbance versus temperature curves and precise temperature monitoring in the cell. Derivative/Log A—calibrated first and second derivative and the logarithm of absorbance for those quantitative analyses of overlapping absorption bands. 20-cm Gel Scanner—for use on polyacrylamide disc gels and autoradiographs. Smart Printer—microprocessor-based to give sample or cell number and absorbance versus wavelength, or absorbance versus time, as hard copy data. Stirrer Accessory—capable of stirring five sample and five reference cells simultaneously.
