GenScript's ToxinSensor Endotoxin Detection System uses FDA approved LAL (Limulus Amebocyte Lysate) testing methods to achieve a fast and highly sensitive endotoxin assay. The Chromogenic LAL Endotoxin Assay kit can quantitatively detect endotoxin in a broad range (0.01–1 EU/ml). The Gel Clot Endotoxin Assay kit is a fast qualitative test showing a positive or negative result.

Reversible Flip Seal—Same Cost, Twice the Lifetime New reversible Flip Seal inlet seals from Restek last twice as long as other inlet seals. Simply use—flip—then use again. The reversible design doubles the number of analyses you get per seal. •Same easy sealing as Dual Vespel® Ring Inlet Seals—no extra washer needed. •Lower leak rate than OEM metal seals. •Maximum transfer of analytes to column, due to highly inert gold or Si…

• Optimized deactivation produces maximum response when analyzing trace levels of acetylene, methyl acetylene, and propadiene. • Stable response factors make this column ideal for process-type applications where recalibration must be minimized. • High loadability reduces peak tailing and improves separations. • Extended temperature range up to 250 °C for fast elution of high molecular weight (HMW) hydrocarbons and accelerated…

A revolutionary new version of Restek’s popular EZGC™ application is now live — it’s easier to use and it’s absolutely free. Just enter your compounds, and this cutting-edge system will recommend not only a GC column, but also the conditions to reliably separate your target analytes. It will even show you a modeled chromatogram! On a PC or Mac, desktop or tablet, the EZGC™ web app can go anywhere and will quickly become your g…

Viva columns are based on a wide pore material we designed for optimal large-molecule separations.In developing Viva silica, we found that although many commercial wide-pore silicas meet the standard 300 Å mean pore size, most have very broad distributions about this mean, with a significant portion of their pore volume falling below 150 Å.This means a large portion of the surface area is unavailable to larger molecules. Viva…
