Filter Funnel, Buchner, 150mL, Med Porosity-29/42

FILTER FUNNELS, BUCHNER, INNER JOINTS, IMPROVED

Buchner style filter funnel having a lower standard taper inner joint and serrated tubulation for connection to a vacuum source. Disc diameters and height above the disc are the same as CG-1402. Improved design incorporates a delivery stem being sealed within the inner joint to prevent breakage. Funnel is supplied with a 3in piece of PTFE tubing that slides over the delivery stem. The tubing permits the funnel to be used during filtrations at higher vacuums without having the fluid pulled into the vacuum source. Overall height is without the PTFE tubing.
