SPE Disks and Cartridges
Waters Corp Sep-Pak Alumina N 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina N Vac cartridges contain a highly active grade of alumina with a neutral 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 neutral alumina is suitable for applications such as synthetic crude oil fractionation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak Diol 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Silica-based polar bonded phase with neutral character; can be used as an alternative to silica in normal-phase applications, where the acidic character of silica is undesirable or as very weakly interacting phase in aqueous applications; applications include antibiotics from cosmetics; isolation of proteins or peptides by hydrophobic interaction chromatography.
Waters Corp Sep-Pak tC18 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 37 - 55 µm, 20/pk
Silica-based bonded phase with strong hydrophobicity; trifunctional bonding chemistry gives it an increased hydrolytic stabilty; applications similar to C18.
Waters Corp Sep-Pak Cyanopropyl (CN) 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Silica-based polar bonded phase; can be used as less polar alternative to silica in normal-phase applications or as less hydrophobic alternative to C18 or C8 in reversed-phase applications; typical applications include drug metabolites and pesticides.
Waters Corp Sep-Pak Aminopropyl (NH2) 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Sep-Pak Amino Propyl (NH2) Vac cartridges contain a moderately polar, silica-based bonded phase with weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanges in aqueous medium below pH 8. Applications include extraction of phenols and phenolic pigments, petroleum fractionation, saccharides and drugs and metabolites. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak tC2 Plus Short Cartridge, 400 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Silica-based bonded phase with low hydrophobicity character; use for methods requiring less retention than C8; applications are similar to C18 and C8.
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.
Chemglass Life Sciences SPE Cartridge, 1000mg Diatomaceous Earth
SPE Cartridge, 1000mg Diatomaceous Earth. Available packed with Silica, Diatomaceous Earth or Un-Packed.
Waters Corp Sep-Pak Cyanopropyl (CN) 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 55 - 105 µm, 100/pk
Silica-based polar bonded phase; can be used as less polar alternative to silica in normal-phase applications or as less hydrophobic alternative to C18 or C8 in reversed-phase applications; typical applications include drug metabolites and pesticides.
Waters Corp Sep-Pak Aminopropyl (NH2) 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55 - 105 µm, 500/pk

Applications include extraction of phenols and phenolic pigments, petroleum fractionation, saccharides and drugs and metabolites. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak C8 Plus Light Cartridge, 145 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Silica-based bonded phase with moderate hydrophobicity; use for methods requiring less retention than C18; typical applications include drugs and their metabolites in serum, plasma or urine, peptides in serum, plasma.
Waters Corp Sep-Pak C8 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 37 - 55 µm, 100/pk
Silica-based bonded phase with moderate hydrophobicity; use for methods requiring less retention than C18; typical applications include drugs and their metabolites in serum, plasma or urine, peptides in serum, plasma.
