Thermo Fisher Scientific develops new suite of UV-Visible and fluorescence analytical solutions

Thermo Fisher Scientific Molecular Spectroscopy : 28 August, 2008  (New Product)
Thermo Fisher Scientific has developed a suite of Thermo Scientific UV-Visible and fluorescence analytical solutions for the life science industry.
From routine UV-Vis absorbance to chemiluminescence, the product range has been specifically designed to allow life science, pharmaceutical and biotechnology laboratories to make sensitive, reliable measurements faster and easier. In addition, Thermo Fisher Scientific has launched a new microsite, available at www.thermo.com/easyassay, to provide detailed information on the expanded portfolio.

Thermo Scientific has extensive experience of producing high quality UV-Vis spectrophotometers that has resulted in the development of the BioMate 6 double-beam UV-Vis spectrophotometer. The instrument 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.

The 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. The compact fluorometer saves valuable bench space and offers storage capabilities for up to nine calibration curves in the internal memory.
