Kimble* Kontes* ULTRA-WARE* HPLC Filtration Cap System

Specially designed to filter HPLC mobile phase directly into the reservoir using 47 mm membrane filters. Optional conversion base allows the use of 90 mm membrane filters for large volume, preparative scale filtration or filtering mobile phase with high particulate loads. Borosilicate glass and PTFE construction gives excellent chemical resistance to all HPLC mobile phases. Cap body is constructed from glass-filled PTFE and is supplied with a TFE/propylene o-ring. In-line filtration with solvent pickup adapter that eliminates traditional pour-and-wait filtration. ¹/₄ in. PFA (perfluoroalkoxy resin) hose barb for easy connection to a vacuum source. Vacuum degassing is accomplished by closing the HI-VAC® valve on the solvent pickup adapter.

Supplied with a filtration cap (with 40-60 micron porosity glass support frit), standard solvent pickup adapter and conical bottom reservoir. Recommended for most solvents used for HPLC mobile phase. O-rings in the solvent pickup adapter must be changed when using tetrahydrofuran (THF) or other aggressive organic solutions. Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements.
