|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.
