Empty Solid Load Cartridges are perfect for loading samples onto a pre-packed column, particularly in the case of low-solubility samples. Dissolve your sample in a suitable solvent, add silica or e.q. diatomaceous earth and after evaporation load the the absorbed sample in the solid load cartridge. The cartridge can be directly placed on top of a pre-packed column via a luer lock conection. Partnumber for 120g cartridge SD-0000-120.
