  • Raptor™ ARC-18 LC Columns (USP L1)

    Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and...

  • Flex-Column Economy Chromatography Columns

    Ideal for use with gel filtration, ion exchange, affinity and adsorption media Economical Easy to use Universal fittings and tubing connections Ideal for use with gel filtration, ion exchange, affinity and adsorption media. Polypropylene reservoirs and column outlets are permanently connected to a...

  • Mini Spe-ed Cartridges

    Applied Separations

    Mini Spe-ed cartridges contain the wide variety of sorbents found in standard Spe-ed cartridges. The Mini Spe-ed configuration (similar to Sep-PakTM) can be easily used in manual syringe operations or on a vacuum manifold. Mini Spe-ed cartridges have a 1.0mL volume. For silica gel, this is 450mg....

    Bond Elut-LMS, 500mg 6mL, 30/PK

  • PRP-1 Reversed Phase HPLC Columns

    Polymeric 100 Å columns for general reversed phase separations. pH stable from 1 to 13 Better sample recovery than silica-based columns (there are no silanol groups) Excellent durability (stable to any concentration of water or organic solvent)   Five particle sizes: 5, 7, 10, 12-20 and...

  • Graphite/Vespel® Ferrules

    Your chromatography analysis does not end with the selection of the GC column. The combination of components selected for your instrument also make an important contribution to successful separations. Choose SGE technology to improve your chromatography.

  • Sep-Pak® Accell Plus CM Plus Light Cartridges

    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...

  • PRP-C18 HPLC Columns

    High efficiency separations at any pH The Hamilton PRP-C18 is a new HPLC column designed to provide high-efficiency, reversed-phase separations over an extended column life in nearly any mobile phase or pH. The rigid stationary phase has excellent mechanical and thermal stability (> 100°C),...

  • Chromatography Columns

    General purpose gravity eluted column having a PTFE stopcock and reinforced beaded top. Column is constructed using MEDIUM WALL TUBING. Glass wool (not supplied) is used to support column packing. Lower end of the column has a round bottom.

  • SYNTHWARE Chromatography Columns with Teflon® Stopcocks & Fritted Disc

    SYNTHWARE general purpose chromatography column with heavy wall design. Supplied with a PTFE stopcock and a reinforced beaded top. With a coarse porosity fritted glass disc to support column packing. Designed for flash chromatography. The section below the disc is carefully minimized to prevent...

  • O Series Reversed-Phase C8 Columns

    Separation Methods Technologies

    O Series SMT SAM-C8 phase with the highest functional ligand coverage confirmed with carbon analysis results of 12% carbon load. In these series, a very high density of the functional ligand, octyl molecule or C8, is achieved through meticulous mixture of the C8 with proprietary spacer molecules to...

  • ZORBAX Eclipse XDB Columns

    Agilent Technologies

    Agilent ZORBAX Eclipse XDB columns – C18, C8, Phenyl and CN – provide four bonded phase choices for method development optimization. These columns provide good peak shape over a wide pH range (2-9) for additional method development flexibility with one family of columns. Eclipse XDB...

  • Rtx-5 (G27) Columns (fused silica)

    low-polarity phase; Crossbond diphenyl dimethyl polysiloxane The diphenyl dimethyl polysiloxane stationary phase is the most popular GC stationary phase and is used in a wide variety of applications. All residual catalysts and low molecular weight fragments are removed from the Rtx-5 polymer,...

  • Molecular Sieve Columns

    Molecular sieve packed columns easily separate permanent gases at above-ambient temperatures. Restek’s R&D chemists have developed a process for preparing molecular sieve packings, which results in excellent batch-to-batch reproducibility. In addition, our molecular sieves are preactivated...
