Proprietary Membranes | Ultra High Quality | Range of Membrane Types
These Advanced Quality brand (AQ™), pre-cut, 25mm & 47mm membrane discs are specifically manufactured from the highest quality materials for HPLC mobile phase filtration and will not add any chemical extractables as you remove particles from your mobile phase which occurs with other brands.
Ultra low extractables
Highest Quality Available
Use with a Vacuum Filter Degasser unit.
Preferred over others brands due to their market leading lowest extractable level. Chosen with solvent filtration for LCMS mobile phases.
Available in hydrophilic nylon or hydrophobic PTFE. Other diameters are available upon request. Use 0.22µm membranes for UHPLC Reversed Phase mobile phases.
