Thermo Fisher Scientific Inc. has developed a complete suite of Thermo Scientific UV-Visible and fluorescence analytical solutions for the life science industry. From UV-Vis absorbance to chemiluminescence, the product offering has been specifically designed to allow life science, pharmaceutical and biotechnology laboratories to make sensitive, reliable measurements faster and easier.
The BioMate 6 double-beam UV-Vis spectrophotometer produces fast, accurate results for a wide range of life science applications, from routine nucleic acid and protein quantitation to research quality enzyme kinetics assays. The BioMate 6 can be upgraded with a variety of accessories to provide precise temperature control, automation, multi-cell analysis and small volume sampling. A flexible oligo calculator feature has also been incorporated to calculate molecular weight, theoretical Tm and the oligo concentration factor.
The Thermo Scientific UV-Vis product offering has been further enhanced with the addition of a new certified DNA standard to verify nucleic acid concentration measurements at 260 nm and purity assessments made using the 260/280 ratio. Often many steps are involved in the synthesis of nucleic acid samples, sometimes resulting in very low yield reactions. This standard provides assurance that the spectrophotometer is providing precise concentration and purity measurements. Developed in an NVLAB 17025 certified laboratory, the standard mimics the spectral features of nucleic acid samples and provides a certified absorption at 260 nm, regardless of the instrument bandwidth. Moreover, a certified absorbance at 280 nm allows a certified 260/280 ratio.
Another addition to the Thermo Scientific suite of UV-Visible and fluorescence products is the Quantech Digital Filter fluorometer, which delivers accurate and sensitive fluorescence measurements, whether it is for the simple analysis of fluorescein or a more complex FRET biological assay. A filter fluorometer provides enhanced sensitivity over monochromator-based scanning instruments, at a fraction of the cost. For researchers who measure concentration by fluorescence or are only interested in the total emission of their sample, the Quantech Digital Filter fluorometer is a cost-effective, reliable solution. This compact fluorometer saves valuable bench space and offers storage capabilities for up to nine calibration curves in the internal memory.
