Designed for molecular biology applications, this grating spectrophotometer features built-in RNA/DNA, oligonucleotide, protein, ａnd optical density （OD） analysis software so that results can be obtained quickly ａnd accurately. Programs include ssDNA, dsDNA, RNA, oligonucleotide calculations, ａnd protein analysis by Bradford, Lowry, Biuret, B.C.A., ａnd direct-UV methods. Analyzer offers method storage, photometric operation, ａnd a selectable wavelength range of 198–1000nm. When powered on, the unit automatically calibrates at three wavelengths, assuring optimal operation. A five-button keypad ａnd large LCD provide effortless interfacing, including sending results ａnd GLP-compliant information to a printer or a PC through the RS-232 port. A xenon lamp provides a broad spectral source of high-energy light using a high-speed flashing function that extends lamp life ａnd lowers operation costs. The analyzer is lightweight, compact, ａnd can fit easily anywhere in the lab.
