Frequently Asked Questions

What is the Whatman 9920-2502 Uniflo H-PTFE syringe filter used for?

The Whatman 9920-2502 syringe filter is designed for filtration of aqueous and organic solvents, making it suitable for HPLC/UHPLC sample preparation, chemical analysis, and laboratory sample clarification. The H-PTFE membrane supports use with aggressive solvents.

What membrane material is used in the Whatman 9920-2502 filter?

The filter has a 0.2 µm pore size and 25 mm diameter, which provides fine particle removal while maintaining efficient flow rates for analytical sample preparation.

What sample volumes are suitable for a 25 mm Uniflo syringe filter?

A 25 mm syringe filter like the 9920-2502 is typically used for moderate sample volumes up to about 100 mL, depending on sample viscosity and particulate load.

What applications are ideal for H-PTFE syringe filters?

H-PTFE syringe filters are commonly used for HPLC sample prep, solvent filtration, biological samples, and mixed aqueous/organic solutions, thanks to their broad chemical compatibility and low adsorption characteristics.
