Membrane Type (PTFE, GHP, PVDF, Nylon) — Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see chart opposite). For aqueous samples, it is preferable to use a hydrophilic membrane (GHP, PVDF or Nylon) versus a hydrophobic membrane (PTFE).

Pore size ratings: Our microfiltration media are offered in a range of membrane filter pore sizes, from 30 nm (0.03μm) to 10μm. Pre-filter and final filter: With various pore size ratings, our membranes support both pre-filter (1.0–10.0 μm) and leading-edge final filter (30 nm–200 nm) applications.

Due to its strength and broad chemical compatibility, PTFE is commonly used in membrane filters. While PTFE is known for its high strength, the addition of a high-density polyethylene (HDPE) backing offers improved filter handling characteristics. Hydrophilic

filter high purity chemicals. The strict requirements for clean materials, as well as compatibility issues, often necessitate the use of fluorocarbon materials. PTFE is an excellent material for filter membrane

General description. These offer high quality filtration for analytical samples. Certified for HPLC to ensure low extractables. Available in a broad range of membranes to meet sample compatibility requirements. The 25 mm Acrodisc is recommended for sample volumes from 5 to 100 mL. The 13 mm size is recommended for samples under 10 mL in volume.
