Designed for busy multi-user laboratories
The Biochrom Libra S80 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.  Results and methods can be stored on board or the convenient USB port 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 easily 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.
Software Modules  Function
Single Wavelength Measurement  Fixed wavelength, Abs/%T, and Concentration (factor)
Wavelength
Scanning  Sample overlays, automatic feature detection and post run data manipulation
Concentration Standard Curve  Quantitation using calibration curves with multiple standards and a choice of curve fits
Kinetics  Serial (or parallel measurements with optional cell changer) including sample overlays and post run data manipulation
Life Science
Methods  DNA, RNA & Oligo concentration and purity measurement with optional wavelength scanning. CyDyeTM DNA quantitation. Tm calculation. Protein concentration by direct UV measurement or Bradford, Biuret, Lowry or BCA colorimetric methods
Equation Editor  Turn your instrument into a "custom application analyzer" by setting up stored methods including calculations based on measured sample data, for example: Absorbance difference and ratios.

Easy to Connect
Two USB ports are provided as standard. One is conveniently located by the user touchscreen to enable USB memory sticks (flash drives) to be be used to both store data and methods in secure and ASCII formats. Particularly useful for laboratories wishing to clone methods between multiple instruments. The other USB port is on the side of the instrument is used for PC communication, control, software update and print via computer (PVC). All stand-alone Biochrom Libra instruments offer users a choice in export and print functionality with selection parameters stored as part of any method.

   Export to PC via USB cable (standard)
   Built in printer (optional)
   Export to a PC via Bluetooth (optional)
   Full PC control with Resolution Software (included)

Resolution PC Software
Supplied with the Biochrom Libra S80 Resolution PC software offers users extra flexibility on data collection and manipulation. Resolution has the power to work in the way you want and includes modules for fixed wavelength, wavelength scanning, kinetics and quantitation measurements plus a validation routine for checking instrument performance. Data export options include Microsoft� Word and Excel� plus Adobe� PDF formats. Optional upgrade modules are also available including Resolution Life for Nucleic Acid and protein measurement and Resolution CFR for 21 CFR part 11 compliance.

Superb Optical Design
High energy throughput double beam optical system with variable bandwidth (0.5nm, 1nm, 2nm, 4nm) gives users the flexibility and performance to measure demanding sample types whilst ensuring EP compliance.

Cell Holders
The Biochrom Libra S80 is supplied with 10mm pathlength cell holders in sample and reference positions.

Accessories
The sample compartment is designed for use with a wide range of accessories. All are designed to be easily changed by users with the minimum of tools. See Biochrom Libra Double Beam Accessories for a full list of optional accessories with order codes.
