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.

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!

The Ultra line represents Restek’s broadest selection of stationary phases on a single silica support.Made of high-purity, type-B silica that minimizes activity and creates high-density bonding, the Ultra Amino Columns (USP L8) are designed for selective and reliable HPLC applications. Particle size: 3 μm or 5 μm, spherical Pore size: 100 Å Carbon load: 2% End-cap: no pH range: 2.5 to 8 Temperature limit: 80 °C USP phase code…
