Idex General Use Inlet Solvent Filters

General Use Inlet Solvent Filters

• Large surface areas prevent pump cavitation
• Disposable
• 2 μm, 10 μm, and 20 μm pore sizes available
• General use and prep filters for higher flow applications

It is good practice to filter your solvents to prevent pump damage. Upchurch Scientific® 316 stainless steel filters provide that protection.

Because filters should be changed periodically, we make it easy to replace them without tools. For those filters using a plastic fitting, the tubing can be reconnected by finger tightening the fitting into the new filter. The filters with stems allow easy insertion into the inlet tubing.

Application NOTE:

Why Use An Inlet Solvent Filter?

• To filter 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 filters 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 efficiently. (Use a 2 μm filter for this purpose.)
• To hold your tubing in place at the bottom of the bottle. (Most stainless steel filter options work best for this purpose.)
• Important Note: It is usually a good idea to change the inlet filter as part of your semi-annual or annual preventative maintenance program.
