UV/Visible Spectrophotometry

UV/Visible Spectrophotometry is a fundamental analytical technique and, together with suitable sample handling accessories, is used in laboratories for absorbance and transmission measurements of samples in all application areas, Biochrom, using its Ultrospec, GeneQuant, Libra and WPA brand names, manufactures and extensive range of attractive UV/Visible products and accessories, with performance and reliability guaranteed by 20 years experience in the field. Amongst other technological advances, these instruments feature PTR (Press to Read) capability, which dramatically extends the lifetime of the source lamps.

• Press To Read (PTR) xenon lamp technology
• Reference Beam Compensation (RBC)
• Instrument Performance Validation (IPV) facility
• 8-position sample changer as standard
• Rapid System Operation

Libra S21 and S22 are simple-to-use instruments with advanced performance, incorporating xenon lamp technology for longer source lifetime and lower maintenance costs. A further benefit of this design is optical noise compensation to improve signal to background measurements. Instrumnet Performance Validation (IPV) is included as standard, and will benefit any laboratory that needs to prove the quality of their results.

In addition to measuring absorbance, transmittance and concentration, they provide a standard curve routine for analyte determination. Wavelength scan, 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 methods can be saved in separate operator folders. The instrument can be upgraded for more sophisticated applications, as well as data manipulation, with Acquire Software and a PC.

With its large sample compartment and wide range of accessories, Libra S21 and S22 and versatile and reliable instruments for use in any laboratory performing general-purpose measurements.
