PEEKBottom-of-the-BottleSolvent Filters
Most recommended fltering unit
100% PEEK polymer construction
Easy operation — no fttings required
These biocompatible filters are made from 100% PEEK polymer,
including the two built-in PEEK frits. The bottom frit (2 µm or 10 µm)
will draw solvents from within 0.080” (2.0 mm) of the bottom of the
solvent bottle. The 2 µm frit on the side may be used for a 1/8” OD
helium sparging line.
To use, simply press
ft your appropriately
sized fluoropolymer
tubing frmly into the
top holes. That’s it!
UHMWPEBottom-of-the-Bottle Solvent Filters
Replaceable flter cup
Economical
Materials of construction: UHMWPE, ETFE
Versions for 1/16” and 1/8” OD tubing
The design of the UHMWPE solvent filters allows tubing to pass
through to the bottom of the flter cup, enabling the flter to draw
solvent fromwithin 0.10” (2.5mm) of the bottomof your solvent bottle.
Please Note: UHMWPE is a hydrophobic material. To establish proper
surface wetting, you may need to prime the filter with methanol
or acetonitrile.
