Like high level spectrophotometers, and contrary to the cheap mounts generally found on instruments of the same category, Easyspec series are fitted with EBERT mount monochromators and quality optics, exclusively mounted on metallic holders (no plastic!). They consequently have a high accuracy, thanks to a very low straylight : <0.05% at 340nm, but overall <0.5% from 320 to 340nm, thus avoiding the big measurement errors involved by higher straylight levels. And because long term reliability is as important as performances, Easyspec series are fitted with sealed optics, and NO chopper, so as to avoid an expensive-to-change wearing part. They have a narrow bandwidth of 5nm (2nm optional), an accuracy of +/-1nm and a repeatability of +/-0.15nm, which make them fit your most demanding requirements. Using cuvettes of different pathlengths and/or tubes generally require laborious dismantlings, and purchasing corresponding holders. On the contrary, Easyspec series are fitted standard with an UNIVERSAL HOLDER for cuvettes from 5 to 50mm pathlength, and tubes of 13 and 25 mm. The instrument is fitted in standard with a serial port (for computer connection), and optionally with a printer port and a 0-1V analog port.
