Certified Sep-Pak Silica 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55-105 µm, 50/pk

Product Description Certified Sep-Pak Silica Vac cartridges contain a polar sorbent that is used primarily to adsorb analytes from non-polar solvents like hydrocarbons, chloro- or fluoro-substituted hydrocarbons, or less polar esters and ethers. Certified Sep-Pak Silica Vac cartridges can also be used in an aqueous medium as a cation exchanger of intermediate strength. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments. Certified Sep-Pak Silica cartridges are quality controlled to ensure reproducible separations. The cartridges provide superior performance for ultra-low-level analyte detection by reducing the potential for background interferences found in many SPE devices. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.

1. What is the Certified Sep-Pak Silica Vac Cartridge used for? It’s used for solid phase extraction (SPE) of analytes from non-polar solvents and as a medium-strength cation exchanger in aqueous solutions. 2. What sorbent material is used in these cartridges? They contain a polar silica-based sorbent with a particle size range of 55–105 µm. 3. Are these cartridges suitable for use with vacuum manifolds? Yes, they are syringe-barrel-type cartridges designed specifically for vacuum manifolds and automated SPE instruments. 4. How much sorbent does each cartridge contain? Each cartridge contains 500 mg of sorbent in a 3 cc format. 5. What makes these cartridges “certified”? They are quality-controlled to ensure consistent separations and reduce background interference for ultra-low-level analyte detection.
