Biochrom Libra S70 Double Beam Spectrophotometers

Product Details

  • Double beam UV/Vis spectrophotometer covering 190-1100nm
  • 1nm bandwidth  and toluene hexane ratio >2.0 for full EP compliance
  • Colour Touch screen display with easy to use software built in
  • USB ports for method and result storage plus connection to a PC
  • Resolution PC software included. Optional 21CFRpart 11 compliance
  • Available with built in thermal printer, Bluetooth® or both.

Designed for busy multi-user laboratories
The Biochrom Libra S70 model is s robustly designed to deliver reliable, low maintenance UV/Visible spectrophotometry in environments with multiple users in a regulated environment such as method development. Users can quickly and easily walk up to the instrument, set up a sample, select the appropriate measurement protocols and collect the results. Store data and methods onboard the instrument or use the convenient USB port that enables individual users to load personal methods and transport data. 21CFR Part 11 compliance via the optional Resolution software.

Easy to use
Colour touch screen user interface with menu driven software and simple intuitive icons is easy to both use and to learn. Results can be easly transported to a remote PC by memory stick for analysis later, or link to a PC directly with PVC software (included). Full PC control with Resolution software

Built in Software
Full suite of software applications provided as standard with real choice of data export methods. Trace Manager enables you to manipulate  data stored on the instrument or USB memory stick. Multi level user log on facility allows supervisors to restrict access to software functionality allowing secure methods to be set up.
