Hydrophilic PTFE Syringe Filter


Microlab Scientific offers Hydrophilic PTFE Syringe Filters, Special ideals on the Hydrophobic PTFE Membrane. Hydrophilic PTFE Syringe Filters are suitable for both Aqueous and Organic solvent filtration. Hydrophilic PTFE syringe Filter is the same as the Hydrophilic PTFE Syringe Filter can be used under  highly aggressive colloidal solutions.

Hydrophilic PTFE Syringe Filters are all- purpose Syringe Filters Similar to Millipore’s Hydrophilic PVDF Syringe Filters and PALL’s GHP Syringe Filters.


• For Analytical and Research applications & for Air sampling.
• Used under extreme chemical or temp Conditions.
• For both aqueous and organic solvent filtration
• Ideal for filtration of highly aggressive colloidal solutions.
• Highly recommended for filtering HPLC samples and mobile phases



• Low protein binding fine particle removal from aqueous and organic solutions
• Accurate analysis HPLC certified for low levels of UV-absorbing extractables
• High flow rates with minimal aqueous extractables
• Low surface friction coefficient: 0.1
• Wide range of working temperature: 180-260℃
