Temperature control - Column Jackets

TJ 150 plastThermostat column jackets SEPARTHERM TJ are universal acrylic glass jackets for heating or cooling of preparative liquid chromatography columns on temperatures between - 10 °C and + 90 °C using a circulating water (or water mixture with salt or organic solvent like ethylene-glycol).
The jacket main part is an acrylic glass tube and tube flanges. Each flange is made of  polypropylene circular plate and polypropylene ring which are connected together by a thread. Between them is a sealing rubber ring to seal the tube.
Chromatographic column is inside the jacket. It is connected by its bottom plate of the jacket by four long bolts. These are used as jacket legs too. Bolts heads are fixed to  a stand plate.
Water from circulating device is coming to a bottom input on the side of bottom circular plate, then is moving along the column up to the upper jacket plate where is an output.
SEPARTHERM TJ jackets are designed to keep on the selected temperature the column itself, nevertheless the column with the jacket is not a close system as the mobile phase is continuously flowing in and out of the column. This phenomenon can have essential influence on the real temperature inside the column. Depending on column dimensions, mobile phase flow rate and temperature may be necessary either to form a spiral exchanger from column input tubing inside the jacket or to use a special exchanger to reach proper temperature inside the column.
