This double-beam, scanning, UV/Visible spectrophotometer, with highly stable optics and two detectors, measure your samples and reference simultaneously providing superior measurement accuracy. A variety of programmed measurement modes for photometrics, concentration, multi-wavelength, spectrum scanning, kinetics, quantitation, and DNA and protein analysis makes it ideal for various applications.
The variable spectral bandwidth provides robust detection and quantitation limits, as well as optimal data precision and repeatability. The flexible platform helps comply with multiple regulatory agencies using one spectrophotometer—saving money and time. The large sample chamber is outfitted with a 10 x 10 mm cuvette holder, but allows for an 8-position cuvette changer (order 83070-61 separately) for flexibility.
The integrated user interface provides local controls with the touch of a keypad. The easy-to-read color graphical display shows spectrum as well as kinetic curves. Use the included Prism PC software to fully control the spectrophotometer and for post-measurement analysis. Software comes pre-loaded with methods for DNA analysis, including 260/280 and 260/230 ratios with 320 nm correction. Measure up to 20 wavelengths simultaneously and create quantitation curves by measuring up to 200 standards.
Operating system compatibility: Windows 2000, XP, Vista, Windows 7
Please Note:Â The Jenway Model number 6850/230VAC has now been rebranded Cole-Parmer under Model number SP-800-UV. All the same great features and specifications, just with a new and improved look.
