Chemglass Flared Vacuum Filtration Adapter 31 mm ID Flange 24/40 Lower Assembly

The Chemglass CG-1053-12 Flared Vacuum Filtration Adapter is a borosilicate glass laboratory component designed to create a sealed system for vacuum filtration using plain stem Buchner funnels. It features a 31 mm inner diameter (ID) flared top, which is specifically designed to accept a #3 rubber "Pluro" stopper (not included, but compatible with Chemglass CG-1401-12). The adapter connects to a receiving flask or filtration flask via a 24/40 standard taper lower vacuum assembly, and it has a side hose connection with a 10 mm outer diameter at its largest serration for attachment to a vacuum line.

Used, in great condition.
