Syringe filters, are often used to remove particles from samples. This is done prior to an HPLC analysis or analysis through other critical instruments. The particles can quickly damage an HPLC by, for example, high pressure.
Syringe filters are intended for small volumes and can be used for filtering gases or removing bacteria from samples. It can also be used to sterilise high-quality additives such as hormones, vitamins, antibiotics or, for example, purified DNA.
A syringe filter consists of a housing (mainly PP) with a membrane disc inside that filters the medium. The medium to be filtered can be either sucked in or pushed through the filter. Syringe filters often have a luer lock connection, but can also be developed according to your wishes.
