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.
