Superb optics
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.

Designed for busy multi-user laboratories
Biochrom Libra S80PC offers a wide range of advanced spectrophotometric capabilities. With powerful optical performance coupled with flexible software users can quickly & easily take their measurements. Built in self test calibrations and validation routines on start up enable users to schedule GLP protocols. 21CFR Part 11 compliance is via optional Resolution software module.

Work the way you want
Having an external PC to control your spectrophotometer and manipulate the data gives you the ultimate in flexibility and control. Whether looking for small differences in multiple spectral overlays, carrying out post-run manipulations on large numbers of samples or simply fulfilling regulatory requirements, Biochrom's Resolution software has the flexibility to work and report in the way you want. 

Resolution software
Supplied with the Biochrom Libra S80PC 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.

Create your custom analyzer
The Method Developer module allows you to customize your Biochrom Libra to suit the exact needs of your laboratory. Set up custom methods to be set up in all applications to include sample prompts containing information such as method SOP timings and the ability to lock individual method parameters. 

Cell holders
The Biochrom Libra S80PC is supplied with 10mm pathlength cell holders in sample and reference positions.

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. Biochrom Resolution CFR Software is available as an optional accessory.
