SPE Disks and Cartridges
Waters Corp Sep-Pak tC18 Vac RC Cartridge, 100 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Silica-based bonded phase with strong hydrophobicity; trifunctional bonding chemistry gives it an increased hydrolytic stabilty; applications similar to C18.
Waters Corp Certified Sep-Pak Florisil 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 50 - 200 µm, 30/pk
6 cc Vac Cartridge of Certified Sep-Pak Florisil, each containing 1 g of sorbent per cartridge.

Waters Corp Sep-Pak Aminopropyl (NH2) 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55 - 105 µm, 30/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 Silica Plus Long Cartridge, 690 mg Sorbent per Cartridge, 55 - 105 µm, 2000/pk
Polar sorbent, used primarily to adsorb analytes from non polar solvents like hydrocarbons, chloro- or flouro-substituted hydrocarbons or less polar esters and ethers.
Waters Corp Oasis HLB Online Prospekt-2/Symbiosis Cartridge, 80Å, 30 µm, 10 mm, 96/pk
The Oasis HLB on-line cartridges for Symbiosis/Prospekt-2 systems are designed for rugged, reproducible, and ultra-fast on-line SPE in the Spark Holland Symbiosis and Prospekt-2 systems. Each cartridge contains 2.5 mg of Oasis HLB, a universal polymeric reversed-phase sorbent for extraction of a wide range of acidic, basic, and neutral compounds from various matrices. Each 800-series tray contains 96 cartridges and can be directly loaded into the Automatic Cartridge Exchange (ACE) or the ACE Feeder units of the Symbiosis/Prospekt-2 systems without the stainless steel tray holder/adaptor.

Waters Corp Sep-Pak C8 3 cc Vac Cartridge, 200 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 C18 1 cc Vac Cartridge, 50 mg Sorbent per Cartridge, 55-105 µm, 2000/pk
Silica-based bonded phase with strong hydrophobicity; used to adsorb analytes of even weak hydrophobicity from aqueous solutions; typical applications include drugs and their metabolites in serum, plasma or urine, desalting of peptides, trace organics in environmental water samples, organic acids in beverages; similar in behavior to reversed-phase HPLC columns.
