Kjeldahl Distillation Bulb, 50 mm

This Kjeldahl bulb improves distillation efficiency by preventing carryover of liquid into the condenser. It is a standard distillation apparatus and can easily be connected to a boiling flask and condenser using the included rubber stoppers. (This one includes a No. 6.5 rubber stopper to attach to 250 ml or 500 ml flasks on one end and a No. 2 rubber stopper to attach to a condenser on the other end.) It's made of borosilicate glass to withstand thermal shock.

The Kjeldahl distillation bulb is included in our Distillation Apparatus Kit and Deluxe Distillation Apparatus Kit.
