Designed for busy multi-user laboratories
The Biochrom Libra S50PC 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.
 
Resolution PC Software
Supplied with the Biochrom Libra S50PC 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.
 
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.
 
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 S50 is supplied with a 10mm pathlength cell holder.
 
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.
