Accurate analytic results in UV/Vis and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol® solvents offer best UV transmittance. In all specifications the minimum transmittance for five typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph. Eur. and ACS.

Pure and Ultra Pure Water System, Milli-Q®, Country box Milli-Q® EQ7000 DE

Supplier: Thermo Fisher Scientific

This RO system with controller provides easy-to-read system parameters. Completely drainable, integrated 100 L high-purity water reservoir has a low-noise pressure booster as a standard component. The compact LabTower RO system is ideally suited as a feed water source for dishwashers, autoclaves and general laboratory use. It serves as a built-in pretreatment unit, consisting of a hardness stabilizer for protection of reverse osmosis module from hardness formers. An activated carbon/5 μm combi-cartridge protects the system against free chlorine and particles which ensures the long service life of downstream purification stages.

Ultra-Plex™ 1-Step ToughMix® is a ready-to-use, 4X-concentrated master mix for reverse transcription quantitative PCR (RT-qPCR) of RNA templates using hybridisation probe detection chemistries such as TaqMan® 5’-hydrolysis probes on Real-Time PCR systems that utilise ROX passive reference with 490 nM excitation. First-strand cDNA synthesis and PCR amplification are carried out in the same tube without opening between procedures. It is ideal for highly sensitive quantification of RNA viruses or low abundance RNA targets in uni- or multiplexed RT-qPCR applications as well as high throughput gene-expression studies. The system has been optimised to deliver maximum RT-qPCR efficiency, sensitivity, and specificity in reduced reaction volumes and fast cycle times. Ultra-Plex™ 1-Step ToughMix® contains all required components for RT-qPCR except RNA template and probe. It is compatible with all dual-labeled probe chemistries.
