Used BECKMAN COULTER DU-800 #9394495 for sale

BECKMAN COULTER DU-800 is a Dual Beam Spectrophotometer designed for research purposes. It is capable of measuring both absorbance and ratio absorbance. It features a space-saving design, with a small footprint that enables it to be used in a variety of laboratory settings. It has a large sample compartment, allowing up to six different sample types, with different cuvettes for each sample type. Originally designed as a 'hand-on' instrument, DU-800 has since been updated with computer-compatible communications, such as USB, Ethernet, and IEEE-488. It also has SCSI, allowing users to conveniently save data from the instrument, and to monitor experiments. Using the Dual Beam Technology, BECKMAN COULTER DU-800 measures the absorbance (or concentration) of a sample, by using a single monochromatic white light source. The beam is split by a beamsplitter, with one part of the split beam being passed through the sample, and then compared resultingly with the other part of the split beam, which remains unaffected by the sample. This allows for not only absorbance readings at any given wavelength to be taken, but also enables a rate-of-change readings to be taken, as there is less sample change compared to the standard single beam absorption measurement. DU-800 is capable of measuring from UV-Vis to near infrared wavelengths, with a spectral bandwidth of up to 5nm. Its concentration measurements are accurate to 0.0005 absorbance units across its range. It has an absorption range from 0 to 3 absorbance units and a transmission range from 0 to 100%. BECKMAN COULTER DU-800 is an excellent general purpose spectrophotometer, well suited for research and biotech laboratories. Its cutting-edge capabilities and space-saving design make it ideal for any laboratory environment.
