Used BECKMAN COULTER DU-800 #9127204 for sale

The BECKMAN-COULTER BECKMAN COULTER DU-800 is a piece of laboratory apparatus used to measure the amount of light that passes through a sample. It is a type of spectrophotometer, which can make quantitative measurements on samples which contain a variety of light-absorbing molecules. DU-800 is a double-beam spectrophotometer, which is equipped with a driver containing two lasers in an optical path. The two lasers, a UV laser (310 Å) and a Visible laser (633 nm), measure the same sample simultaneously, enabling fast, reliable absorbance measurements. BECKMAN COULTER DU-800 is capable of self-calibration over the entire dynamic range of wavelengths, which is between 249 and 999 nm, with a detection limit down to 1 Decimal absorbance value. Its dynamic range is further enhanced with a high-sensitivity accessory. DU-800 is capable of collecting data from multiple samples and performing rapid sample-to-sample comparisons. In addition to its absorbance capabilities, BECKMAN COULTER DU-800 is uniquely suited for fluorescence absorbance experiments due to two powerful fluorescence lamps and two additional filter wheels, which can be used to filter any unwanted signals out. DU-800 is also capable of fluorescence anisotropy, time-resolved and phosphorescence measurements. Furthermore, the D‑800's sample compartment features a variable temperature stage and a stirring system, which can be used to control sample temperature and provide quick measurement of concentrations at varying temperatures. BECKMAN COULTER DU-800 also features a control system for precise automation of the measurement sequences, and the data is stored in a fast, reliable refrigerator storage media. Users have the option to program their own custom-tailored measuring sequences. This instrument's reliability and versatility makes it the perfect tool for a range of laboratory processes and applications. DU-800 is used in a variety of scientific analyses, such as DNA/RNA quantification, protein quantification, enzymatic reactions, and quantitative drug diagnostics.
