SPE Disks and Cartridges
Waters Corp Waters Oasis HLB Vac Cartridge, 20 cc, 1 g, 60 μm
The 20 cc Oasis HLB cartridges, featuring a 60 μm particle size, utilize a universal polymeric reversed-phase sorbent for extracting a wide range of compounds. The sorbent is water wettable, ensuring high retention and excellent recoveries even if it dries out. These syringe-barrel-type cartridges are ideal for vacuum manifolds and automated SPE instruments.
- Made from hydrophilic N-vinylpyrrolidone and lipophilic divinylbenzene monomers.
- Stable at pH extremes and in various solvents.
- Offers extraordinary retention of polar compounds.
- Three times higher hydrophobic retention than traditional silica-based SPE.
- Improves recovery and reproducibility by retaining more analytes.
- Water wettable for consistent performance.
- Suitable for viscous samples.
Waters Corp Sep-Pak Accell Plus CM Plus Light Cartridge, 130 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus CM Plus Light 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 have a distinctive finned outer body and a reduced internal diameter, which results in an interstitial volume about one-third that of the corresponding Plus-style cartridge. This design allows you to elute fractions in a minimal volume to improve recoveries and reduce solvent consumption, a benefit especially for applications where samples are limited or where excessive dilution is a concern.
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.
Waters Corp Certified Sep-Pak Vac Cartridge, Alumina N, 6 cc, 1 g, 50–300 μm
These Vac cartridges offer active alumina with neutral surface chemistry. The aluminum oxide surface provides polar analyte retention and Lewis acid properties. This normal phase sorbent is more stable than unfunctionalized silica under high pH, ideal for synthetic crude oil fractionation. Quality controlled for reproducible separations, they provide superior performance for ultra-low level analyte detection, reducing background interferences. Syringe-barrel-type for vacuum manifolds and automated SPE instruments.
- Highly active alumina, neutral surface.

- More stable than silica in high pH.
- Suitable for synthetic crude oil fractionation.
- Quality controlled separations.
- Superior for ultra-low analyte detection; reduces interferences.
- Syringe-barrel-type for vacuum manifolds/automated SPE.
Waters Corp Waters Sep-Pak Classic Cartridge, C18, 360 mg, 55–105 μm
This silica-based bonded phase with strong hydrophobicity is designed to adsorb analytes, even those with weak hydrophobicity, from aqueous solutions. It is similar in behavior to reversed-phase HPLC columns.
