Syringeless and syringe filters are used for the removal of interfering materials and fine particles prior to injection. Filters are suitable for both aqueous and organic samples, and are often constructed from PVDF or PTFE. Whether your research necessitates prefiltration, sample preparation, sterile filtration, laboratory filtration, or gas venting, Thermo Scientific™ Nalgene™ syringe filters are lab essentials. Thermo Scientific™ Choice™ PVDF (hydrophobic) Syringe Filters is also an excellent option for general biological filtration.
