Ace Glass, 9599-49, Spinning Hickman-Hinkle Column with Side Port, Microscale
This apparatus is really a hybrid system. It is a concentric tube/spinning band distillation column. The purpose of the band is to control flooding of the concentric tube (the shaft of the PTFE band). High plate values are achieved by expanding the shaft diameter to the maximum amount until flooding occurs. Plastic tubing is fitted around PTFE band area of column for insulation. Column hold-up is approximately 20ul. Temperature range of this non-reduced pressure still is 45 to 110C. The top joint of this heavy walled still is a combination cap, thread and joint to accommodate and seal other microscale apparatus. The O.D. of the top joint has an external thread to facilitate an O-Ring and open-top phenolic cap. The internal or I.D. at the top is a ground 14/10 outer joint. 14/10 inner joint at bottom. Complete item consists of modified Hickman still, Claisen head, PTFE band, thin-walled vial, plastic insulator, and operating instructions.
