The 6850 is a flexible machine that unites different functionalities into one device. With it, users can confidently access the different modes available based on their specific needs. The modes covered include photometrics, spectrum scanning and DNA/RNA and protein analysis. Other modes include multi-wavelength, kinetics and quantization. .With the 6850 the user gets the benefit of double beam spectrophotometer. The advantage with this arrangement is that the device has a variable spectral bandwidth into the Jenway range. The accuracy of the measurements are guaranteed because the device has stable optics and two detectors. These work together by measuring both sample and reference at the same time.
