Spectrophotometer Libra S22 UV/Vis
Easy-to-use split beam spectrophotometer with xenon lamp technology for longer source lifetime and lower maintenance costs. With reference beam compensation (RBC) for the removal of optical interference to improve signal to background measurements. In addition to the measurement of absorption, transmission and concentration, wavelength scans (with zoom), kinetics, reaction rate determinations and standard curves can be displayed as graphics. User defined equations can be entered using multi-wavelength mode and up to 18 methods can be saved in separate operator folders. 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 attached qualification and performance verification logbook so that an ongoing record of instrument performance over time may be kept for GLP purposes.
