What Is a Condenser Tube?

A condensing tube is a kind of laboratory equipment used to promote condensation. It plays a role of condensation or reflux. It usually consists of two glass tubes, one inside and one outside. The smaller glass tube runs through the larger glass tube. ^[1]

Condensate return

When there are volatile liquid reactants, in order to avoid loss of the reactants and make full use of the raw materials, a condensation reflux device should be designed in the generating device. After the condensation, the material will return to the liquid state from the gaseous state, and then reflux and collect. The laboratory can be achieved by installing long glass tubes or condensing return tubes in the generator.

Straight condenser

Straight condenser

It is composed of a straight glass tube with internal and external combination. It is mostly used for distillation operation. The steam temperature is less than 140 degrees, and it cannot be used for reflux. There are connecting pipe joints on the upper and lower sides of the outer pipe, which are used to make the water inlet and the water inlet. How to use: When using, connect the lower end of the connection to the faucet with a plastic tube as the water inlet. The temperature of the water at the inlet is lower and the water heated by the steam has a higher temperature; the hotter water will automatically flow upward due to the decrease in density, which will help the circulation of cooling water.

Air condenser

Straight condenser

Air condensers and straight condensers are mainly used when distilling out products (including distillation and fractional distillation). When the boiling point of the distillate exceeds 140 degrees Celsius, air condensers are generally used to prevent the straight condenser from passing through the water to cool the glass and cause large temperature differences. Exploded.

Condenser tube

Spherical condenser

The inner tube is connected by several glass balls, which is used for the reflux of organic preparation, and is suitable for various boiling liquids.

After long-term use, the rust in the spacer can be washed away with hydrochloric acid. Disadvantages: Condensed liquid tends to get stuck in glass spheres after solidification. Due to the high water pressure at the water inlet, the hose is easy to fall off, and it must be tied with iron wire when in use.

Condenser

Serpentine condenser

Reflux for organic preparation, suitable for liquids with lower boiling points.

Double plug condenser

Contains two grinding plugs. The taper diameters of the grinding plugs are different. It is convenient to choose the taper diameter during inspection, one at the top and two at the other.
