COLORIMETERS? SPECTROPHOTOMETERS? We have numerous models to choose from. Only six of the many different colorimeters and spectro photometers we stock are pictured here. They range in price from $310.00 for a Klett-Summerson Colorimeter . . . to $5,500.00 for the sophisticated Coleman Model 124-D Spectrophotometer — a solid state, double-beam, ratio-recording instrument with direct digital readout of absorbance, transmittance, and concentration. Inbetween, there are such other colorimeters and spectrophotometers as the Coleman Model 9 NephoColorimeter, various B&L Spectronic 20s, and Coleman Models 111, 139, 46 and "Juniors", to name a few. There are also numerous accessories and attachments for use with the different models. Of course not only do we sell colorimeters and spec trophotometers, but we stock over 30,000 other items. So whether you are in the market for a simple little test tube or a sophisticated laboratory instrument, we can meet your requirement. Ask us for literature.
