Beckman Coulter’s DU Series 700 spectrophotometers are advanced and affordable systems that generate accurate and reproducible measurements. The narrow bandwidth allows users to scan samples with excellent resolution. With its focused-beam design, the system provides optimal and reproducible results for small samples, capabilities usually found only on more expensive systems. The systems have a unique touch-screen user interface with easy-to-use but powerful software. A wide range of applications software is included and makes the DU Series 700 the perfect solution for life science, research and analytical labs. Standard Features include CSV file format for data transfer, USB ports, spectral bandwidth of 3.0 nm, operator and sample ID’s, a wavelength range from 190 to 1100 nm, a focused beam design, quick interchange of cell holders and modules, password protection with security list and automatic lamp turn-off.
The narrow beam width of the system ensures excellent results for small samples in semi-microcells. With the focused beam, there is no need for masking, and the entire energy is utilized to provide a wide dynamic range and excellent linearity. With this design, small variances in cell positioning have no effect on the reproducibility of user’s results.
For even smaller samples, the popular 50 ÂµL microcells from Beckman Coulter can be used with a specifically designed cell holder. The cells are easy to clean and, if not diluted, precious DNA, RNA, or oligonucleotide samples can be quickly recovered.
Advanced Features on some model’s of the series include startup diagnostics and a range of system checks to guarantee that the instrument performs to specifications each day, and temperature control for single samples with the optional Peltier temperature control module, ideal for enzyme samples. Both the UV and Visible lamps can be turned off automatically and independently to protect lamp life and save cost. USB ports for printer, memory device, and keyboard. Data can be transferred to a PC quickly and easily in CSV format (comma-separated values). The CSV format has become the standard import format for spreadsheets and LIMS. It has built-in transport mechanism for 7-position carousel and password protection with individual access control (security list). With the DNA/Protein Tools (DU 730 only), calculations, common conversions, and lookup tables are at user’s fingertips
