General use and prep flters for higher fow applications
It is good practice to flter your solvents to prevent pump damage.

316 stainless steel flters provide that protection.
Because flters should be changed periodically, we make it easy to
replace them without tools. For those flters using a plastic ftting, the
tubing can be reconnected by fnger tightening the ftting into the new
flter. The flters with stems allow easy insertion into the inlet tubing.

Inlet Solvent Filters
Why Use An Inlet Solvent Filter?
To flter out particulate matter from the solvent that may otherwise damage
expensive hardware. (Use a 10 µm or 20 µm version for this purpose. The
A-309 and A-230A flters have an added “Bottom of the Bottle
™
” feature to
help draw solvent to within 1/8” of the bottom of your solvent bottle.)
To prevent particulates originating from the sparging system from
entering the mobile phase reservoir and to help disperse the sparging
gas effciently. (Use a 2 µm flter for this purpose.)
To hold your tubing in place at the bottom of the bottle. (Most stainless
steel flter options work best for this purpose.)
Important Note: It is usually a good idea to change the inlet flter as part of
your semi-annual or annual preventative maintenance program.
