Application Specific Data

Regenerated Cellulose

as a hydrophilic membrane suitable for aqueous and organic media; not suitable for aggressive acids and bases (good moistening properties, wet durable).

PTFE

as a hydrophobic (water repellent) membrane suitable for organic solutions and aggressive acids/bases or cryo liquids (chemically high resistant);
for aqueous filtrations pre-washing with Methanol is required to make the membrane more hydrophilic.

Nylon (PA)

as a hydrophilic membrane suitable for aqueous and organic media.
