Corning® Pyrex® Cold Finger Condenser
By Corning
This simple Pyrex® cold finger condenser, of relatively low efficiency, is often used to regulate refluxing by adjusting the flow of air or water through it (dephlegmation). The tubulation O.D. is approximately 10mm. This condenser has a 24/40 inner Standard Taper joint and is a replacement part for organic chemistry kit, No. 6949.
