Easyoperation—no fittings required
These biocompatible filters aremade from 100% PEEK polymer,
including the twobuilt-inPEEK frits. Thebottom frit (2µmor 10µm)
will draw solvents fromwithin 0.080” (2.0mm) of thebottomof the
solvent bottle. The 2µm frit on the sidemaybeused for a 1/8”OD
helium sparging line.
To use, simply press
fit your appropriately
sized fluoropolymer
tubingfirmly into the
topholes. That’s it!

Versions for 1/16” and 1/8”OD tubing
The design of the UHMWPE solvent filters allows tubing to pass
through to thebottomof the filter cup, enabling the filter todraw
solvent fromwithin0.10” (2.5mm)of thebottomofyoursolventbottle.
PleaseNote:UHMWPE isahydrophobicmaterial.Toestablishproper
surface wetting, youmay need to prime the filter withmethanol
or acetonitrile.
