The Thermo Scientific Spectronic Genesys Visible Spectrophotometer 20 incorporates the latest technologies for reliable results and easier operation. A sleek design houses up-to-date electronics and a grating-based, 1200 lines/mm optical system. The tungsten-halogen lamp offers approximately 1000-hour lifetime.
The spectrophotometer features a narrow, 8 nm slit width with built-in filters that are automatically selected for a given wavelength. A large, easy-to-view 2-line, 20-character LCD readout displays data and on-line instructions. Clear messages indicate error conditions. The wavelength (a wide 325 to 1100 nm operating range) is conveniently selected using touch pad arrow keys. Simply select the mode of your choice using the A/T/C key. To run concentration, just follow the instructions on the display! If no standard is available, simply input the factor.
The flexible cuvette holder accommodates 10 mm square cuvettes, 10 mm test tubes, and GENESYS™ 20 Visible Spectrophotometer, 1⁄2" test tubes. Optional long-path cell holders are also available. Versatile data output is provided by a built-in, fully functional bi-directional RS-232C interface and built-in Centronics printer port.
