Lyophilization has become a standard practice in the pharmaceutical industry since the beginning of its first applications around the 1940s. Since then, the lyophilizer has gone from being a simple vacuum drying equipment to become a highly sophisticated and integrated system, combining a number of processes to ensure systematic production according to technical and biological specifications.
Lyophilization is a process that aims to separate the liquid (water or other solvent) from an organic material, or from a solution, by freezing and then sublimation of the ice at reduced pressure, thus generating a dehydrated product without altering its qualitative and quantitative composition, that is to preserve the molecular structure of the substance to be preserved. This is achieved through the use of a freeze-drier.
The standard type vacuum freeze drier is suitable for laboratory experiments. The freeze-drier is widely used in medicine, pharmacy, biological research, chemical industry and food production, etc. After the freeze-drying process, long-term preservation of the products is much easier. They can be restored to their original state and maintain their chemical and biological characteristics after watering. Vacuum freeze drying technology, also called sublimation drying, is a technical method that freezes samples in advance and then sublimates their moisture in a vacuum state.
Lyophilization or freeze drying is a process in which water is removed from a product after it is frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor without passing through a liquid phase. The process consists of three separate, unique, and interdependent processes; freezing, primary drying (sublimation), and secondary drying (desorption).

At Kalstein we are manufacturers of laboratory equipment of the highest quality and at the best prices on the market. This time we present the lyophilizer YR05186 is suitable for laboratory freeze-drying experiments. This lyophilizer is widely used in medicine, pharmacy, biological research, chemical industry and food production. After the freeze-drying process, the long-term preservation of the products is much easier. They can be restored to their original state and maintain their chemical and biological characteristics after watering.
The heat contained in the lyophilizer provides the necessary energy to the water to pass to the gaseous state, accelerating the process. And the gas that's left loose, is condensed at low temperatures, returning back to solid state.

Freezers are highly sophisticated equipment, and thanks to technological advances there is a great variety, which are perfectly adapted to the field of application in which they are used. We have freeze-driers that are used in the food industry, whether it's to make space food, military food or dehydrated food.
In this section you will find, our freeze dryers in operation, packaged, receiving service, etc.
Firstly, the material to be freeze-dried is frozen at sub-zero temperatures, thus maintaining its molecular structure. The frozen material is inserted into the freeze drier, where there is a vacuum pressure, due to the action of a vacuum pump that allows it to function properly. This pump allows 95% of the water present in the sample to be sublimated, and in this way, the product dries without the need to use temperatures above the ambient temperature.
The heat contained in the lyophilizer provides the necessary energy to the water to pass to the gaseous state, accelerating the process. And the gas that's left loose, is condensed at low temperatures, returning back to solid state.
