SPE Disks and Cartridges
Electron Microscopy Sciences Forensic Certified SEM Mount 6 mm pin
This mount is made from a special certified Aluminum alloy which does not contain any of the objectionable elements that may interfere with samples collected for GSR . These mounts are 12.7 mm x 11 mm.
Waters Corp Sep-Pak Florisil Plus Light Cartridge, 145 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.
Waters Corp Sep-Pak Alumina A 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 50 - 300 µm, 100/pk
Sep-Pak Alumina A Vac cartridges contain a highly active grade of alumina with an acidic surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica; however, it is slightly more stable than unfunctionalized silica under high pH conditions. This acidic alumina is also low-capacity ion exchanger in aqueous media. Unlike polymer-based ion exhangers, this sorbent is unaffected by high-energy radioactivity and can be used for radioactive compound isolation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak Accell Plus CM Plus Short Cartridge, 360 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus CM Plus Short 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 cartridges are provided in the short-body configurations for easily attachment to pumps and syringes. They can also be fitted with removable reservoirs and used on vacuum-assisted flow devices and certain automated systems.
