SPE Disks and Cartridges
Waters Corp Sep-Pak Accell Plus CM 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus CM Vac cartridges contain a silica-based, hydrophilic weak cation-exchanger with large pore size (300Å). The cartridges are designed for extraction of cationic analytes in aqueous and non-aqueous solutions. The large pore size makes it ideal for isolation of molecules such as cationic proteins. Other applications include extraction of steriods, pesticides, and herbicides. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak Porapak RDX 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 125-150 µm, 30/pk
Specially cleaned polymeric poly(divinylbenzene-vinylpyrrolidone) resin with hydrophobic character. Can be used as an alternative to octadecyl-bonded silica for preparation of analytes that weakly adsorb to silica-based reversed-phase sorbents. Compatible with sample or eluents at high and low pH. Specifically designed for the concentration of high explosives in aqueous samples.
Waters Corp Sep-Pak Florisil 3 cc Vac RC Cartridge, 500 mg Sorbent per Cartridge, 50 - 200 µm, 50/pk
Polar, highly active, weakly basic sorbent for adsorption of low to moderate polarity species from nonaqueous solutions.
