Mobile Phase Sparge Filter; Inlet Filter
The 2 µm helium sparge filter is an inexpen-
sive way to prepare and maintain mobile
phases free of dissolved gas. Both filters are
made from 316 stainless steel and PEEK™ and
are compatible with most solvents.
Last Drop Filter
The flat filter element sits parallel to the
bottom of the mobile phase reservoir,
allowing the filter to draw 98% of the
mobile phase without drawing air into the
system. Conventional cylindrical mobile
phase filters begin to draw air into the
system when approximately 10% of the
solvent remains in the reservoir. The Last
Drop Filter allows more analyses per
batch of mobile phase and helps reduce
hazardous waste. 22.1 mm OD.

Low-Pressure Slip-On Inlet Filter for Mobile Phase
Reservoir
A type 316 stainless steel tip with a Tefzel® collar seals to a cor-
rosion-resistant type 316 stainless steel filter element. The slip-on
filter easily attaches to the pump inlet line, without the use of
wrenches. The universal tip accommodates standard Teflon®
tubing inner diameters. The cylindrical filter is standard 10 µm
porosity.
