Linear Condenser Tube

November 1, 2021

The instruments used in laboratories are many, they vary according to their function, size and measure. Among them, there is the linear condenser tube, they have among their functions to store and protect substances. For this reason, laboratories are widely used.

The linear condenser tube is used to convert the vapor that a distillation gives off by means of refrigerant substances found in the tube.

It should be noted that our entire way of life is a consequence of the advances that human beings have managed to develop. But, these inventions and knowledge would not have been made without research in science laboratories where each material or instrument has played an important role.

What is a Linear Condenser Tube?

It is also called a refrigerant tube , it is a device made of glass, whose purpose is to condense the vapors that come from distillation. It has two circuits that are separate.

The water inlet is made through the lower part of the tube and its outlet through the upper part, it is placed in an inclined way for better results.

What is the Linear Condenser Tube for?

The linear condenser tube serves to carry out the reflux of the hot vapors, which dissolves and cools in the condenser, allowing the reduction and elimination of the solvent and thus better heating the mixtures for a long period.

The refrigerant liquid, almost always is water, this has to circulate properly so that it obtains the appropriate temperature and allow the condensation of the vapors.

However, apart from water, this type of condenser can be cooled through other cooling fluids, such as ethanol that can be thermostatically cooled through a recycle pump unit. The use of liquids other than water allows the condenser to be able to cool down to below 0 ° C.

Using the Linear Condenser Tube

This instrument is generally used for reflux, where hot vapors of a liquid solvent, which are heating in the flask, are cooled and allowed to drip.

This process will help reduce solvent loss considerably. It also allows the mixture to heat up for long and extended periods .

It is used in laboratories, generally in experiments that need to mix organic liquids that can become a gaseous state, through heating. Although they can also be used in the area of ​​inorganic chemistry, as well as others.

Types of Linear Condenser Tube

The condensers can be of various types, so that the laboratory processes can be carried out satisfactorily. Among the types of linear capacitors that exist, the following stand out:

Air condenser

The heat from the liquid spreads through the glass and is cooled by the air outside. It is generally used in fractional distillation and when high temperature condensation is performed.

  • Vigreux condenser

It is used as a column for fractional distillation. They tend to be a bit more expensive than the traditional ones. Unlike other tubes, it has inside a series of downward breaks, which serve to considerably increase the surface of the condensation.

  • Liebig condenser

It is a very simple model to condense by water. Inside its tube is completely straight. In this type of condenser a large amount of incoming steam can be condensed than in others.

  • Graham condenser

It is known as a spiral condenser. It has a coil that runs through the entire tube . It also has an element to conduct the refrigerant, which is its outer tube, where condensation takes place inside its spiral.

  • Dimroth condenser

It has a double internal spiral. The inlet and outlet are the cooling media. This type of capacitor is more efficient than the traditional coil type.

  • Allihn condenser

This type of condenser can also be known as the reflux condenser, it is a glass tube where the liquid can pass through its outer part. It has bulges in its inner part in order to increase the condensation surface of the steam .

  • Friedrichs condenser

It is in a large internal spiral that contains a large cylindrical capsule. The liquid or refrigerant circulates through the internal tube and as it condenses, it evaporates and cools.

After knowing the types of linear capacitor that exist, your choice will be based on the need and requirement of the researcher.

Characteristics of the Linear Condenser Tube

To know the proper way to use the linear condenser tube, it is important that you know what its characteristics are. The linear condenser tube is characterized by:

  • It has two cylindrical tubes. The interior that will be where the vapors to be condensed circulate and the outer tube where the cooling liquids circulate.
  • Its ends are made by glass joints.
  • In order to prevent the entry of water, the upper part can be left open and fully ventilated.
  • The outer part of the outer tube has a connection so that the coolant can enter and exit
  • The coolant has to be continuously in circulation so that it has a temperature to condense the vapor in the best way.

Another important characteristic is that this type of tube does not need a very high flow for proper cooling to take place.

Importance of the Linear Condenser Tube

In the field of biological sciences and chemistry, as well as in the field of clinical analysis, a laboratory must be provided with linear condenser tubes, in order to carry out all kinds of tests and measurements with accuracy.

It should be ruled out that in any type of laboratory it is required to have highly specialized instruments , which are key to developing and carrying out different experiences.

It is important to know and identify the different laboratory tools or instruments, because in this way the researcher is able to use them correctly. As well as calling them by name and knowing what it is for, and giving it the correct use.

The linear condenser tube is a fundamental element in any laboratory. Likewise, it is necessary, since through its specialized use it comes to form a team of tools that will help to obtain accurate and effective data.

Born and raised in Brussels in an English family, I have always lived in a multicultural environment. After several work experiences in marketing and communication, I came to Smart Water Magazine, which I describe as the most exciting challenge of my career.
I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
