Biochrom Libra Spectrophotometers and Colorimeters
Biochrom Libra S21 Visible Spectrophotometer
Features
- Split Beam (RBC) Visible spectrophotometer covering 325-1100nm (<3nm bandwidth)
- PTR Xenon lamp technology saves running costs
- Wide range of accessories
- Instrument Performance Validation (IPV) facility
- 8-position sample changer as standard
Description
The Biochrom Libra S21 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 optical noise compensation to 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 S21 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).
