Superb Optics
High energy throughput double beam optical system with fixed 1nm bandwidth gives users the flexibility and performance to measure demanding sample types whilst ensuring EP Compliance.

Designed for busy multi-user laboratories
Biochrom Libra S70PC offers a wide range of advanced spectrophotometric capabilities. Multi user logins enable individual users to have a customized settings and a personal method portfolio enabling them to get results quickly. 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 PC Software
Supplied with the Biochrom Libra S70PC 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.
