Due to its low protein binding, this syringe filter is recommended for sterile and clear filtration of culture media, buffers etc. and of aqueous solutions in general.

The clean and pure nylon membrane com- bines the fastest flow rates with a low unspecific binding. Includes pre-filter made of fiberglass. Thus, this syringe filter can be used anywhere where the application or the clear filtration is allowed under unsterile conditions, as usually in the sample preparation before HPLC or GC.

The PTFE membranes are biologically and chemically inert and have high flow rates. The PTFE membrane is availa- ble in a hydrophobic and in a hydrophilic version.
