Filters — Laboratory Consumables

Filtration protects columns, sterilises media and clarifies samples. This group covers syringe filters, bottle-top vacuum units, membrane discs, centrifugal concentrators and inline solvent filters for HPLC. The membrane decides compatibility, so buyers should match it to their solvents and analytes. Pharmaceutical users often reference USP <788> for particulates and USP <665> or USP <1664> for extractables, while sterile devices can be packed to EN ISO 11607.

Applicable standards

USP <788> (particulate matter in injections) USP <665> (plastic components and systems) ISO 13485 (medical device quality management) ISO 10993 (biological evaluation of medical devices) EN ISO 11607 (packaging for terminally sterilized devices) USP <1664> (assessment of drug product leachables)

How to specify

Select membrane material by solvent: PTFE for organics, PES or PVDF for aqueous samples.
Use 0.22 µm pore size when the goal is sterilisation, 0.45 µm for clarification.
Ask about hold-up volume when working with small or costly samples.
