Laboratory crystallizer, what is it and how much does it cost?

November 2, 2021

The crystallizer is a laboratory instrument that is generally used in both chemistry and biology ; It is made with borosilicate glass  that can also be called Kimax, Pyrex or Duran, which are usually much more popular.

The main function of crystallizers is the process that leads to the crystallization of the solute from a solution , or even to the sterilization of certain solutions. Likewise, the crystallizer is a container with a wide base , between 8 and 30 cm in diameter and of short stature; This shape ensures greater efficiency for the evaporation of the solution, in addition to being cylindrical and having a fused edge, which also turns out to be very useful, especially in those with a peak.

Types of crystallizer and their dimensions

Peakless crystallizer

This can be used for the storage of the solutions and the crystallization itself. Their dimensions tend to be larger, they can range from a capacity of 150 ml to 7000ml , but they can also be found with a capacity of 500ml, 1500ml, 4000ml, among others. Its height can vary between 4 cm to 15 cm.

Crystallizer with spout

Since these have such a spout, they are ideal for pouring liquids into other containers. Its main function is sterilization due to the ease offered by the spout in question, that when it is finished using it, its content can be transferred without risk of spillage . Its dimensions are much smaller than those of the crystallizer without spout, being its minimum capacity of 250ml, 500ml, 1000ml and its maximum of 1500ml . Its height ranges from 5 cm to 9 cm.

Crystallizer functions

The crystallizer is made of a highly resistant material against factors as diverse as temperature changes, prolonged and constant contact with acids, as well as the ability to withstand different chemical elements regardless of their harmfulness or contamination and a minimum expansion towards heat, which turns out to be very useful to be able to use it in various processes.

Thanks to all these functions, the crystallizer can be used for different procedures, be they typical of chemistry or biology, let’s see it below:

– Evaporates the liquid from a solution , making it easier for the solute to crystallize; This process turns out to be widely used even in foods that are consumed daily , such as chocolate, ice cream, sugar and sea salt, simply that it is carried out on a larger scale.

– Can be used for dry or steam sterilization ; This process is carried out to achieve an example equivalent to baking in microorganisms , since when exposed to high temperatures their proteins are changed due to oxidation. It is recommended that this process be carried out with the hot air method in laboratory crystallizers.

– Another way in which it can be used is as a lid or container , usually for solutions that have already been crystallized previously in said instrument.

– It is also useful in occasions where it is necessary to pour the solutions after having been treated. In this case only the peak crystallizer should be used and substances should be handled with care.

– Its capacity to contain solutions with a high pollutant load or those that have a high concentration of raw materials should also be highlighted , all due to the already treated resistance of the material.

How to use the crystallizer

The way to use the laboratory crystallizer is very simple, since it is used almost exclusively to be able to achieve the drying and crystallization of the solids that may be present in any solution; its cylindrical shape and flat base seek to offer optimal and greater evaporation of these solvents.

Although, it also offers a storage function for various substances that is appreciated, since none of these substances, are stored before or after the chemical process that is available, cause damage to the container.


Crystallization is a chemical process that has been perfected over the years. Its basis is the use of gases at high or low temperatures that can change the molecules, ions or atoms of a liquid or solution, thus forming a network-shaped bond which will end up generating the base of a crystal as it is known. Commonly. This process is very present in the purification of solid substances.


Its main function is to eliminate or kill the microorganisms that contaminate a substance and once the process is carried out, it is not possible for it to become contaminated again. Using a laboratory crystallizer, this process is achieved with heat and is used in substances that have a high protein content such as chloroplasts or metallic or reflective materials.

Example of crystallization

A very clear example of crystallization is a salt experiment, in which the crystallizer must be filled with hot water to about half its capacity. Then salt must be added to the water and dissolved with a spoon, so that no remains remain and the water is saturated. At that moment, we must introduce a bottle of smaller size but higher than the crystallizer inside the other and in the upper part a pencil must be placed with a string tied in the middle and that has a clip at the end; once this is done we must wait for the water to cool down.

When the water has cooled down, a salt crystal will have formed in the paper clip , which rises up the string to the pencil; this is by far the most common example of crystallization.

Laboratory crystallizers turn out to be very useful tools, which can be implemented for different functions due to the quality of their material, which turns out to be very efficient for processes involving heat or cold, which makes it a necessary implement in any laboratory .

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.
