Sep-Pak Silica Classic Cartridge, 690 mg Sorbent per Cartridge, 55-105 µm, 2000/pk

With the Sep-Pak Silica Classic Cartridge, you can easily extract and transport your solvents, solutions, and samples without worrying about spillage or sample loss due to evaporation. As a precision chromatographic tool for sample enrichment and purification, the Sep-Pak C18 Classic Cartridge is a piece of dependable lab equipment.

The Sep-Pak Silica Classic Cartridge comes packed with the best quality packings that have been specifically designed and manufactured for sample processing. The packings are clean and dry, and activity and capacity are reproducible. The Sep-Pak C18 Classic Cartridge's packing also provides excellent surface area, pore size, and particle size distributions. The lab equipment’s sorbent is polar and is used primarily to adsorb analytes from non-polar solvents like hydrocarbons, chloro- or fluoro-substituted hydrocarbons, or less polar esters and ethers.

You can use the Sep-Pak Silica Classic Cartridge, knowing that the product integrity will be preserved. Because the lab equipment is sealed in a non-contaminating poly-foil packet, the product integrity, packing inactivity, and purity are all maintained until the package is opened in your lab.

The 20 µm frit in the Sep-Pak Silica Classic Cartridge is constructed up of a mix of HD and UHMW polyethylenes. The frit has good solvent resistance, low extractable levels, and good flow characteristics. It can also be used as a depth filter, retaining minute amounts of sample debris. In addition to this, the lab equipment is manufactured in a cGMP, ISO 9001 certified plant using ultra-pure reagents under the strictest manufacturing conditions. Each step of the process is closely monitored and the finished products tested to ensure that you only receive the highest quality lab equipment as Waters promises.

We also recommend that you explore and invest in the TruView LCMS Certified Clear Glass 12 x 32 mm Screw Neck Vial, with Cap and Preslit PTFE/Silicone Septum, 2 mL Volume, 100/pk so you can store your analytes in an inert storage unit without worrying about any contamination or interference in the results.
