Kimble® KONTES® ULTRA-WARE® Filtering Flasks with Side Arm

This KONTES® safety-coated filtering flask is manufactured from heavy-walled borosilicate glass to assure the mechanical strength needed for vacuum filtration. It has a No. 8 rubber stopper joint and a No. 2 hose connection. The side arm accepts standard 1/4in (6 mm) inner diameter tubing for connection to vacuum sources. A second flask should be connected between the filtering flask and the vacuum source to prevent accidental entry of the filtrate into the vacuum line or pump.
