Ace Glass 9599-49 Hickman-Hinkle Column Complete

Low cost Microscale distillation column designed similar to 9576 Hickman still with threaded side port on reservoir, but with elongated section below well to accommodate a longer PTFE spinning band. When operated carefully, the Hickman-Hinkle column will yield 6-10 theoretical plates (data from Bowdoin College reports that this type column achieved an equivalent to HETP of better than 0.33cm/plate).

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 110°C. 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.
