Büchner Funnels, Improved, Glass Frit with Vacuum Takeoff

These Büchner-style filter funnels have a lower standard taper inner joint and serrated tubulation for connection to a vacuum source. The improved design incorporates a delivery stem that is sealed within the inner joint to prevent breakage. The funnel is supplied with a 3" piece of Teflon™ tubing that slides over the delivery stem, permitting the funnel to be used during filtrations at higher vacuums without having the fluid pulled directly into the vacuum source.

The disc diameters and height above the disc are the same as the corresponding CG-1402 model but this item is available only in sizes from 30 to 600 mL in coarse and medium porosities with 24/40 or 29/42 joints

See our porosity size chart for size information and Glassware Gallery for care and usage tips.
