Funnels/Flasks
ULTRA-WARE® Filtering Flask with Rubber Stopper Joint This flask is manufactured from heavy wall borosilicate glass to ensure the mechanical strength needed for vacuum filtration.
Buchner Funnel with KIMFLOW® Fritted Disc This Buchner KIMAX® funnel is used wherever filter paper and membranes cannot withstand the chemical attack of the filtrate. • Funnels are constructed with heavy-walled stems, and top rims are beaded for extra strength • With a marking spot • With KIMFLOW® fritted disc • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
•
Side arm accepts 3/8” ID tubing for connection to vacuum sources
•
Rubber stopper joint
• Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements A second flask should be connected between the filtering flask and the vacuum source to prevent accidental entry of the filtrate into the vacuum line or pump.
