Beckman Coulter Spectrophotometer UV VIS is ideal for research, analytical, and life science labs, these advanced spectrophotometers generate accurate and reproducible measurements. Beckman Coulter Spectrophotometer UV VIS systems feature a focused-beam design to provide optimal results for small samples. A narrow bandwidth allows samples to be scanned with excellent resolution. The Beckman Coulter Spectrophotometer UV VIS are equipped with a unique touch-screen interface with powerful, easy-to-use software that has a wide range of applications. Up to 50 user programs or methods can be defined and stored for quick recall. Beckman Coulter Spectrophotometer UV VIS feature password protection and USB 1.1 ports for a printer, memory device, and keyboard. Data may be stored in the Beckman Coulter Spectrophotometer UV VIS or on a USB memory stick. Both the UV and visible lamps feature automatic shut-off and independent operation. To assure performance and adherence to specifications, the Beckman Coulter Spectrophotometer UV VIS employs startup diagnostics and a wide range of system checks. Performance validation tests check wavelength accuracy and bandwidth, photometric accuracy and reproducibility, photometric noise, stray light, and drift. Both the DU 720 and DU 730 Beckman Coulter Spectrophotometer UV VIS are suitable for fixed wavelength, wavelength scan, kinetics/time, and single component analysis (SCA) applications. The Beckman Coulter Spectrophotometer UV VIS DU 730 life science model is equipped with software featuring DNA/protein tools and also handles protein assay analysis, nucleic acid analysis, and dye incorporation. The nanoSPEC package includes the DU 730 model and the nanoVette fiber optic measurement cell for DNA/RNA and protein sub-microliter analysis. The nanoVette is supplied with a 0.2mm pathlength lid; for other nanoVette options, see BKA44097series. The sipper module performs quick and convenient measurements of multiple samples without the need to transfer samples to cuvettes. A peristaltic pump draws the liquid into the 350µL flow cell, takes a reading, then discharges the liquid or returns it to the source. The sipper module includes a tubing kit and may be used with the single-cell holder or the multi-cell holder. The Peltier temperature control module holds a single cell and is ideal for enzyme kinetic experiments or any procedure requiring accurate temperature control. It ensures each sample is measured at a specified temperature from 15 to 50°C (59 to 122°F). The temperature control module should be used with 1cm quartz cuvettes. The multi-cell holder can accommodate 1, 2, and 5cm rectangular cuvettes, as well as 2.5cm (1") round and rectangular cuvettes. The carousel holder has seven positions for 1cm cuvettes (including semi-microcells) and works with the built-in transport mechanism in the spectrophotometers. The microcell holder holds one 50µL microcell. The turbidity cell holder holds one 1cm cuvette.
