PTFE membranes are particularly suitable for preparing samples for HPLC analysis. The hydrophobic nature of
the membrane also has applications for air and gas sterilization. The membrane is laminated onto a non-woven
polypropylene support web for improved strength and handling and can be used at temperatures up to 150ºC.
PTFE is the membrane of choice for use with the aggressive solvents, liquids and gases that can attack Other
membranes. It is resistant to most acids, alkalis and solvents.

One of the major applications for the PTFE filter is the clarification of corrosives, solvents and aggressive fluids.
This includes the important requirement in HPLC analysis for sample filtration where any solid particles can cause
permanent damage to the column. The 0.45µm pore size is normally used.

Hydrophilic PTFE membrane is optimized for low drug and protein binding with excellent throughput in typical aqueous
and solvent Sample Preparation. High sample recoveries and low extractables provide for optimum analysis by HPLC
and LC/MS/MS. The membrane is suitable for applications including natural product screening, aqueous solubility testing
and total drug analysis.

Sizes are available as 13 mm, 25 mm, 47mm, 90mm,142 mm, 293mm cut disks in a range of pore sizes from 0.1–5 µm.
