Available with either PP, PTFE or nylon membrane. Membranes are available in either 0,2 or 0,45 µm pore size, with the choice often made on analytical column packing size. If the column packing size is larger than 3 μm then use 0,45 μm, and if 3 μm or smaller then use 0,2 μm.
- Suitable for HPLC: Low levels of UV-detectable extractables
PP membrane: These polyvalent filters are designed for the preparation of mixed samples. They fulfil a broad range of chemical compatibility for aqueous/organic mixtures.
PTFE membrane: These PTFE membranes are designed for filtration of corrosive gases and organic solvents. Excellent chemical resistance. Ultimate compatibility for filtering harsh chemicals.
Nylon membrane: These versatile filters are suitable for the preparation of aqueous and solvent-based samples. Chemical compatibility with esters, bases and alcohols. Offers a broad chemical resistance to common solvents. Not recommended for acids >1N or halogenated solvents.
