Economical, digital 5nm bandwidth spectrophotometers available in Visible or in UV/Vis configurations. Features easy-to-see and use push buttons to control the unit or it can be controlled via computer using the optional software package (see below).

Digital spectrophotometer features a precise, 1200 lines/mm grating monochromator and has a narrow 5nm bandpass for high stability and accuracy. The front panel has a large, two line LED, and easy-to-use keypad to select wavelength and operation mode, and to autozero a blank. Unit has RS-232C interface.

Both units offer a large sample compartment with a 4-position cell holder for standard 12.5 x 12.5 x 45 mm cuvettes (10 mm path length). Additional holders are available for test tubes, single cuvettes, rectangular longpath cuvettes and cylindrical cells. The micro cell package includes an adjustable base and single cuvette holder for 50 and 100 µl microcells (Z dimension: 15 mm). Optional software allows for complete control without pushing buttons (see below). Units come standard with a dust cover and a pair of optical glass square cuvettes (10 mm). Units are 110/220V switch selectable and are CE-approved.

* All holders include universal base, required for installation
