Distillation Components Distillation Heads
Still head, available with/without side port, is used to carry out simple and fractional distillations

This apparatus is 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 20 μL. 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 standard taper 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 standard taper 14/10 outer joint. standard taper 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.

Head has an elongated section below well to accommodate a PTFE spinning band for yields of 6-10 theoretical plates. Still has top 14/10 threaded outer joint, 14/10 inner bottom. Top joint supplied with cap, O-Ring and septa. Column has an elongated section below well to accommodate a longer PTFE spinning band, includes still, claisen head, PTFE band, vial, insulator, thermometer.
