6850 Double Beam Spectrophotometer

Double beam spectrophotometer with highly stable optics
Variable spectral bandwidth 0.5, 1, 2, 4, 5nm
Integrated user interface
Conforms to European Pharmacopeia requirements
Jenway Prism PC software included as standard
Extensive range of accessories available

The new 6850 introduces the first double beam spectrophotometer with a variable spectral bandwidth into the Jenway range. The highly stable optics and two detectors measure the sample and reference simultaneously optimising measurement accuracy. The 6850 has measurement modes for photometrics, concentration, multi-wavelength, spectrum scanning, kinetics, quantitation, DNA/RNA and protein analysis. 

Jenway Prism PC software is supplied as standard and offers additional functionality, extensive post-measurement tools, unlimited results saving and easy export of data. The 6850 is ideal for quality control, general research, pharmaceutical, biochemical and clinical laboratory applications.
