Buchner style filter funnel features a lower standard taper inner joint.

• Serrated tubulation for connection to a vacuum source
• Disc diameters and height above the disc are the same as Buchner funnel
• Improved design incorporates a delivery stem being sealed within the inner joint to prevent breakage
• Funnel is supplied with a 3" 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.
