Our uniquely designed Bottom-of-the-Bottle Filters effectively protect your system by filtering out particulate matter that my otherwise damage expensive hardware. Our durable stainless steel specifically designed to allow solvents to be drawn from within 1/8 inches of the bottom of your bottle. Our UHMWPE version allows tubing to pass through to the bottom of the filter cup, enabling the filter to draw solvent from within 0.10 inches (2.5 mm) of the bottom of your solvent bottle. This widely known and durable polymer is an economical choice. Our PEEK version is biocompatible and includes two built-in PEEK frits. Our PEEK frit (2 μm or 10 μm) will draw solvents from within 0.080 inches (2.0 mm) of the bottom of the solvent bottle. The 2μm frit on the side may be used for a 1/8 inches outer diameter helium sparging line.

Flangeless Fittings eliminate the need to flange tubing. This removable and reusable system provides several benefits such as providing flangeless chromatography fittings for observing mixtures and solvents. Flangeless Fittings are easy to use. Just slip the nut and ferrule over the tubing and finger tighten the assembly into your receiving port. Our Flangeless Fitting require minimal downtime because component replacement is quick, taking only a few seconds. Flangeless Fittings systems typically require only one new ferrule at minimal cost when repairing a connection.
