Spectrophotometer - Model UV-Visible Double Beam

Spectrophotometer - Model UV-Visible Double Beam JENWAY

6850 UV | Visible Double Beam Spectrophotometer  

The new 6850 introduces the first double beam  

spectrophotometer with a variable spectral band-  

width 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.  

Features  

• 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
