Product Description
A filter flask that connects by ground joint gives a tighter, more secure fit than a rubber stopper alone. These flasks let you attach jointed filter funnels or adapters directly while the sidearm draws vacuum, speeding up suction filtration and solvent recovery.
This listing is for Kimble catalog number 617500-0005: KONTES Filtering Flask, Glass Side Arm, Ground Joint, 500 mL. Each flask is made from 33 expansion low-extractable borosilicate glass that meets USP Type I and ASTM E438 Type I, Class A. A 24/40 standard taper outer joint sits at the neck, and a serrated glass sidearm hose connector accepts 3/8 inch ID vacuum tubing. Capacities of 250 mL and 500 mL are offered. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
