Beckman Coulter DU 800 UV/Vis Spectrophotometer
This Beckman Coulter DU 800 UV/Vis Spectrophotometer is for life science, academia, biotech, and pharmaceutical applications. With a Windows*-based software interface, the DU 800 handles complex analyses and basic administrative functions with ease. Software is designed to simplify daily analyses, including those regulated by the FDA, and fully supports compliance with FDA Regulation CFR 21 Part 11 (Electronic Records; Electronic Signature).
The integrated user interface of the DU 800 software provides convenient and useful features such as quick access to system functions, continuous display of status and method parameters, and the ability to take quick readings or scans without exiting the current application. The spectrophotometer has many unique features, including a source scheduler that can turn both the UV and visible lamp on and off independently at specified times each day; a performance validation scheduler that warms up the system automatically and then performs specified test(s) at a given date and time; and cell matching, which corrects minor differences in multiple cells. Designed with a micro-focused beam, the DU 800 delivers the full energy of the beam to the microsample, unlike standard beams which can lose as much as 80% of their energy when applied to a microvolume sample.
Transports are for automatic positioning and movement of samples in the unit. The standard transport is compatible with all ambient and water temperature regulated accessories. The high performance transport is compatible with all ambient and water or Peltier temperature regulated accessories. Note: The appropriate Peltier controller is required when electronic temperature control is desired.
Concentration Package — Ideal for essential biological/analytical applications. Includes the DU 800, a single cell holder, and a 4.2mL UV silica cuvette, as well as DNA ratios.
