• Stopcocks have PTFE plugs, and the column has a 40-60 micron porosity fritted disc • Joints are Standard Taper 19/22 except for the extension tube, which is Standard Taper 7/25 • Ref: OACS Official Method Ca9f-57, JAOCS Vol. 46, No. 5, Pages 252-255 • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements Free fatty acids and miscellaneous non-fat substances are removed by passing the sample through a column of activated alumina. Losses are then calculated.
ULTRA-WARE® HPLC Filtration Cap Systems • 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” PFA (perfluoroalkoxy resin) hose barb for easy connection to a vacuum source
