Description
The Biochrom Libra S22 is a simple-to-use instrument with advanced performance, incorporating Xenon lamp technology for longer source lifetime and lower maintenance costs. A further benefit of this design is Reference Beam Compensation (RBC) to remove optical noise and improve signal to background measurements.  

In addition to measuring absorbance, transmittance and concentration, wavelength scan (with zoom), absorbance changes with time, reaction rate determinations and standard curves can be displayed as graphics and printed out. User defined equations can be entered using multi-wavelength mode and up to 18 methods can be saved in separate operator folders.

The S22 can either download results to Excel via spreadsheet interface software (optional) or upgraded for more sophisticated applications, as well as data manipulation by full PC control using the optional Acquire Software.

Designed for regulatory compliance
This instrument is ideal for industrial laboratories seeking GLP, IQ/OQ certification test plans and output to LIMS. The on-board self test diagnostics for instrument performance validation may be used in conjunction with the Qualification and Performance Verification Logbook (provided with the instruments) so that an ongoing record of instrument performance over time may be kept for GLP purposes. For 21CFR part 11 compliance, Acquire CFR software is required (optional).
