A kind of glass apparatus which condenses the condensing gas into liquid by heat exchange principle. There are three kinds of straight, spherical and serpentine, and the specifications are expressed in length (mm), with 150~300 etc. Used for distilling liquid or organic reserve, starting condensation or reflux. Use range: the temperature of the steam is greater than 140 degrees Celsius, the air condensing tube is used, the temperature is less than 140 degrees centigrade, and the straight condenser tube is used.

Use range: the temperature of the steam is greater than 140 degrees Celsius, the air condensing tube is used, the temperature is less than 140 degrees centigrade, and the straight condenser tube is used.
The condensing tube is usually used in a flask intended to do the experiment on the reflux condition or to collect the retort on a condensed liquid. The condensation of the vapor occurs in the inner wall of the tube. The enclosed space is the function of absorbing the heat and removing the heat from the water area. There is usually a high water pressure in the inlet. In order to prevent the pipe from falling off, the plastic tube should be fastened with the tube bundle. When used in the reflux state, the tube of the lower end of the condenser is inserted into a rubber plug that can be inserted into the flask to hold the vapors that evaporate in the flask.
Reflux condenser tube
Of volatile liquid reactant, in order to avoid loss of reactants and make full use of raw materials, to reflux device in generator design, make the material by condensation after by gas recovery for the liquid-cooled condensing tube, thereby back flow and collection. Lab can install long glass tube through the generator and condenser tube formed by combination of inside and outside straight tube, used for distillation operating steam temperature is less than 140 degrees, not for return. There are joint pipe joints on the upper and lower sides of the outer tube for outlet and inlet.
Direct condensation tube usage: when used, the lower end connector shall be connected to the faucet with plastic pipe as inlet. Because of the lower water temperature at the inlet, the water is heated by the steam and the temperature is higher. The lower density of the warmer water will automatically flow to the upper reaches, which will help the cooling water circulation.
Air condenser pipe and straight type steam condenser pipe is mainly used at the time of the product (including distillation and fractional distillation), when boiling point distillation of more than 140 degrees, the use of air condenser pipe, general lest straight shape condenser pipe is cooled lead to great difference in temperature of glass and burst.
The spherical condensate tube is connected to a number of glass spheres and is used for the return of organic preparation for the liquid of various boiling points.
After long use, the rust in the septum can be washed with hydrochloric acid. Disadvantages: after condensation, the liquid is easy to get stuck in the glass bulb. Because the inlet water pressure is high so the rubber tube is easy to fall off, use wire to tie. The condensing tube condensing tube is used for the backflow of organic preparation, which is suitable for the liquid with lower boiling point.
The cone diameter of the grinding plug is different with two grinding plugs. The cone diameter can be easily chosen at the inspection time, and a top two.
