Stainless Steel Bottom-of-the-Bottle Solvent Filter Assemblies feature replaceable stainless steel filter cup and a design that allows solvent to be drawn to within 1/8” of the bottom of solvent bottle. The filter cups are inexpensive and easy to replace, making this an economical, trouble-free choice.

     PEEK biocompatible Bottom-of-the-Bottle Solvent Filter has two PEEK frits. The bottom frit (2?m or 10?m) will draw solvents to within 0.08” (2mm) of the bottom of the solvent bottle. The 2?m frit on the side may be used for a 1/8” OD helium sparging line.

     UHMWPE Bottom-of-the-Bottle Solvent Filter comes with a disposable 10?m ultra-high molecular weight polyethylene (UHMWPE) filter cup. These filter cups thread directly into the inert Tefzel? (ETFE) body, creating a good seal that ensures all mobile phase is properly filtered. Choose from versions designed for use with 1/16”, 1/8”, 1/4” and 5/16” OD tubing.
