The PL series of continuous wave (CW), grating tuned, infra-red gas lasers sets the standard for high power, stable sources for a wide variety of applications from molecular spectroscopy, non-linear optics, interferometry, process control, atmospheric studies, plasma density measurements and much, much more. The PL-series of lasers include grating tuned CO2 lasers with a step tunable wavelength from 9-11μm with single line pow…

The EPL picosecond pulsed diode lasers are a new excitation source for fluorescence lifetime measurements that bridge the gap between the nanosecond flashlamp and expensive mode locked Titanium Sapphire femtosecond lasers. The EPL lasers are pre-adjusted for an optimum pulse width, with particular attention paid to reducing a secondary shoulder. The output has a guaranteed pulse width of less than 100 picoseconds. The EPL lase…

The EPLED picosecond pulsed LEDs are a new excitation source for fluorescence lifetime measurements. In Time Correlated Single Photon Counting (TCSPC), they bridge the gap between the nanosecond flashlamp and expensive mode locked Titanium Sapphire femtosecond lasers in the UV region. The EPLEDs are pre-adjusted in respect to pulse width and peak power, with particular attention paid to reducing both secondary shoulder and a l…

DATAN 3.0OverviewWith DATAN 3.0 characterization of chemical equilibria and chemical reactions becomes easy. DATAN exploits the great advantage of collecting entire spectra and even higher order experimental data when studying chemical samples. Behind a user friendly interface state of the art algorithms, several of which are proprietary to MultiD, are used to extract chemical information about the samples with minimum assumpt…

A new member of the HyPURITY® family introduced at Pittcon 2003, HyPURITY AQUASTAR™ columns are a new silica-based polar end-capped C18 which is designed to offer superior retention of polar compounds and increased sensitivity in 100% aqueous conditions. Product detail:A new member of the HyPURITY® family introduced at Pittcon 2003, HyPURITY AQUASTAR™ columns are a new silica-based polar end-capped C18 which is designed to off…

BioBasic AX Columns o   Improved reproducibility, efficiency and column lifetimeso   Range of stationary phases to optimize selectivityo   Powerful resolution, even on short column lengths Product detail: New BioBasic AX (weak anion exchange) columns have a polyethyleneimine (PEI) ion exchange group and a polymer coating, specifically designed to give robust and clean performance in ion exchange of acidic proteins and pep…

Chromatin Immunoprecipitation (ChIP) is an important technique allowing the researcher to analyze in vivo interactions of proteins with genomic DNA. Any chromatin-associated or DNA binding protein can be analyzed with this technique, provided a good antibody to the protein exists. One can measure different proteins localized to a specific region of the genome, or the genome wide distribution of a specific protein. Another powe…

The EZ-Zyme™ Chromatin Prep kit allows ChIP analysis at nucleosome resolution by performing complete or partial digestions with a proprietary enzymatic cocktail to obtain chromatin fragments of on average one to a few nucleosomes in length. Compared to sonication, this procedure not only allows mapping the protein-DNA association at a higher resolution, but also renders the subsequent immunoprecipitation more efficient due to…

Sterivac vacuum-driven filter units are ideal for bottle-top filtering directly into receiver flasks at flow rates as fast as 1.5 L/min. The unique "start & stop" filtration action makes setting up, filtering and transferring the unit to another receiver fast and easy. Push a button to stop filtering, move the device to an empty bottle and restart
