Specifications Double beam spectrophotometer with highly stable opticsVariable spectral bandwidth 0.5, 1, 2, 4, 5nmIntegrated user interfaceConforms to European Pharmacopeia requirementsJenway Prism PC software included as standardExtensive range of accessories availableThe 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 with preloaded methods for DNA/RNA and protein analysis, as well as extensive post-measurement tools, unlimited results saving and easy export of data.The 6850 double beam spectrophotometer is ideal for quality control, general research, pharmaceutical, biochemical and clinical laboratory applications.Parameter6850Wavelength range190 to 1100nmWavelength resolution0.1nmWavelength accuracy± 0.3nm (at 0.5 and 1nm bandwidth) ± 0.5nm (at 2, 4 and 5nm bandwidth)Wavelength reproducibility± 0.2nmSpectral bandwidthVariable 0.5, 1, 2, 4, 5nmPhotometric range- 0.3 to 3.0A 0 to 200%TPhotometric accuracy± 0.002A (0- 0.5A) ± 0.3% T (0- 100%T)Photometric reproducibility± 0.001 Abs (0 to 0.5 Abs) ± 0.002 Abs (0.5 to 1.0 Abs) 0.15%T (0- 100%T)Resolution0.1%T, 0.001AStray light< 0.05%T at 220 and 360nmNoise0.0005AStability± 0.001A/h at 500nm after 15 min warm upMulti-wavelengthUp to 10 wavelengths, up to 20 wavelengths with PC softwareCalculationsRatio, difference, formulae with factorsSpectrum rangeAny range between 190 and 1100nmScan speed100 to 2000nm/minScan interval0.1, 0.2, 0.5, 1, 2 or 5nmAnalysisAuto peaks and valleys, zoom .
