SPE Disks and Cartridges
Waters Corp Sep-Pak Accell Plus CM 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 37 - 55 µm, 20/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 Vac Cartridge, Alumina A 500 mg, 3 cc, 50 to 300 μm
Waters Sep-Pak Alumina A Vac cartridges are ideal for normal-phase separations and radioactive compound isolation. They feature a highly active, acidic alumina sorbent that provides an extremely polar surface for analyte retention. These cartridges also offer enhanced stability under high pH conditions and can function as low-capacity ion exchangers.
- Highly active grade of alumina with acidic surface chemistry.
- Aluminum oxide surface provides an extremely polar surface for analyte retention.
- Acts as a Lewis acid for diverse applications.
- More stable than unfunctionalized silica under high pH conditions.
- Functions as a low-capacity ion exchanger in aqueous media.
- Unaffected by high-energy radioactivity, suitable for radioactive compound isolation.
- Syringe-barrel design for use with vacuum manifolds and automated SPE instruments.
Waters Corporation Oasis HLB Plus Short Cartridge, 225 mg Sorbent, 60 μm, Reversed Phase
Oasis HLB Plus Short cartridges use Oasis HLB, a universal polymeric reversed-phase sorbent, for extracting diverse compounds from various matrices. Water wettable, ensures high retention and recovery even if dry.
