The condenser used for distillation applications has coil-formed inner tube that increases surface area for cooling the condensed liquid for high-speed condensing.The glassware is composed of borosilicate glass that has a low coefficient of thermal expansion and is resistant to thermal stress. Inlet and outlet tubes are mounted on opposite sides of the tube.
Glass cold finger coiled type reflux dimroth Condenser
Glass apparatus is very popular in the laboratories and many chemical industries. Our glass apparatuses are made of borosilicate glass or quartz glass that has good corrosion resistance and high temperature resistance. They will not be corroded by chemical materials. And we can observe the experimental situation through the transparent surface. We have glass condenser and glass oil water separator.
Glass coil condenser/ heat exchanger main advantages
1.Heat exchange tube and shell welding directly, without leakage between casing and tube wall
2. Due to use 3.3 high borosilicate glass, have very strong corrosion resistance, heavy metals and impurities will not be separated, provide the best environment for manufacturing high purity products
3. Flexible assembly, can through the series or parallel, meet the needs of different heat transfer area
Coil tube heat exchanger mainly used for condensation and cooling, can also be used for the liquid heat carrier heating

4. Maximum working pressure:
positive pressure( gage pressure):0.1MPa
negative pressure:The pressure difference between the shell and tube side is less than 0.1MPa
Usage:The condensing pipe is composed of a combination of inner and outer glass pipes. There are connecting pipe joints on the upper and lower sides of the outer pipe. The water supply port and the water outlet condensing pipe should be connected with the plastic pipe when the lower end connection port is used. The faucet, as the water inlet, is heated by the steam because the water temperature at the inlet is low, and the temperature is higher; the hotter water of the steam will automatically flow upward due to the decrease in density, which helps the circulation of the cooling water. The condensation occurs on the inner wall of the inner tube. The space enclosed by the inner and outer tubes is such that the water area absorbs heat from the vapor and removes the heat.
Reminder: the water inlet usually has a high water pressure. In order to prevent the water pipe from falling off, the plastic tube should be tied with a tube bundle. When used under reflux conditions, the lower end glass tube of the condensation tube should be inserted with a rubber stopper to enable plugging. Into the mouth of the flask, to receive the vapor evaporated upwards in the flask.
