SPE Disks and Cartridges
Electron Microscopy Sciences TorrLube Bottle Torrlube Oil 60 CM3
TorrLube Oil is an extremely pure PFPE (Perfluoropolyalkether ) blend which is thoroughly distilled and then filtered through a submicron screen. TorrLube Oil has the ability to withstand thermal expansion and contraction as well as chemical and mechanical stress, while still maintaining consistent viscosity. These properties make TorrLube the ideal lubricant for bearings, automated slides, and screws that have a tendency to gall or cold weld while working under extreme conditions.
A set of two small bottles, each containing 60cc of TorrLube lubricant. Every bottle comes with a sealed cap. A luer lock cap and a #22 gauge blunt needle are provided for closed application. The bottle set is appropriate for larger manufacturing units and production fabs. Each twin pack of TorrLube 60cc bottles is sealed to prevent leakage and contamination.

Chemically treated with a proprietary reverse phase adsorbent, single layer borosilicate glass ValuSep™ SPE Filters (47mm) can filter the 40 mg/L EPA PAR standard in approximately 10 minutes with significantly faster filtration times for 1 L NPDES-type samples. ValuSep™ SPE Filters offer high recoveries and low blanks at a great price.
Waters Corp Sep-Pak Aminopropyl (NH2) Vac RC Cartridge, 100 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Sep-Pak Amino Propyl (NH2) Vac RC 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 cartridges feature an integral 20 cc funnel-shaped reservoir for convenient processing of larger volumes of samples. They can be used with robotic sample preparation equipment or with vacuum manifolds.
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 Sep-Pak tC18 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 37 - 55 µm, 30/pk
Silica-based bonded phase with strong hydrophobicity; trifunctional bonding chemistry gives it an increased hydrolytic stabilty. Typical applications include analyte isolation and enrichment from biological, env?ironmental and food samples.
Waters Corp Sep-Pak tC18 Plus Long Cartridge, 900 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 Sep-Pak Accell Plus CM Classic Cartridge, 360 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus CM Classic 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 Classic-style cartridges are designed for use with positive displacement by a Luer-tip syringe and can also attach easily to vacuum-assisted flow devices using a male/male adaptor.
Waters Corp Sep-Pak C18 Classic Cartridge, 360 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.
Waters Corp Sep-Pak Alumina A 35 cc Vac Cartridge, 10 g Sorbent per Cartridge, 50 - 300 µm, 10/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 Cyanopropyl (CN) 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 55 - 105 µm, 30/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 Diol 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 37 - 55 µm, 30/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 Accell Plus QMA 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 37 - 55 µm, 30/pk
Sep-Pak Accell Plus QMA Vac cartridges contain a silica-based, hydrophilic, strong anion-exchanger with large pore size (300Å). The cartridges are designed for extraction of anionic analytes in aqueous and non-aqueous solutions. The large pore size makes it ideal for isolation of larger molecules such as anionic proteins such as immunoglobulins and enzymes. Other applications include isolation of phenolic compounds and removal of acidic pigments in wine, fruit juices, and food extracts. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
