Hydrophobic and hydrophilic PTFE syringe filters

Hydrophobic PTFE/H syringe filters are indicated for cleaning small sample volumes for HPLC or GC analysis, where maximum chemical resistance is required.

The hydrophobic membrane offers high chemical resistance to most solvents and acids and is autoclavable.

Hydrophobic PTFE/L syringe filters are suitable for aqueous and aggressive organic solvent-based solutions and are especially ideal for HPLC samples. The modified membrane exhibits broad chemical resistance and unsurpassed temperature stability to address aggressive sample situations or high-temperature situations.
