Designed for busy multi-user laboratories
The Biochrom Libra S60PC model is robustly designed to deliver reliable, low maintenance UV/Visible spectrophotometry in environments with multiple users. Users can quickly and easily walk up to the instrument, set up a sample, select the appropriate measurement protocols and collect the results. 21CFR Part 11 compliance via the optional Resolution software.

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 S60PC 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 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 S60PC 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.
