Type 205: Cellulose nitrate, sterile. Certified to meet requirements of standard methods for water quality control for microbiological analysis, sterility tests, food and beverage testing. Individually wrapped.

Type 210: Cellulose acetate, non sterile, autoclavable. Filter for sterilisation of proteinaceous solutions. Low adsorption of proteins from serum or culture media. Resistant to alcohol and oil, can be used in short-term contact with methyl ethyl ketone, suitable for liquid scintillation counting. Must be wet when autoclaved.

Type 215: Nylon, hydrophilic, non sterile, autoclavable. For both aqueous and organic solvent filtrations. Usefull for sterilisation and clarification of buffers and culture media, ideal for HPLC solvents and ultracleaning solutions for electronics laboratories. Low levels of extractables, contain no wetting agents. Less brittle and easier to handle than cellulose.
