Containers for storing samples in liquid nitrogen are made of stainless steel, and are characterized by maintaining a very low and stable temperature for a long time. Biological samples such as tissues, cells, embryos or semen are very valuable and delicate. Because of this, their storage must be carried out under special conditions. This allows them to stop the metabolic processes taking place in them. Samples are stored either directly in liquid nitrogen or in containers where nitrogen does not come into contact with the products because it is in the walls of the container. Very stable and uniform storage conditions can be achieved in liquid nitrogen vapor where temperature distribution is highly uniform and temperature fluctuations are minimized. Nitrogen is a colorless gas under normal conditions, and at a temperature of -185.8 degrees C it condenses (under normal pressure), which produces liquid nitrogen. In this form it is often used in laboratories as a cooling and thermostatic medium. Suitable containers, made of stainless steel for storing liquid nitrogen vapor, are used where the use of liquid nitrogen is required. In order to avoid the transition of nitrogen back into a gaseous state, Dewar vessels are used. They have a structure similar to a household refrigerator. Their outer and inner layers are separated by an engineered vacuum. As a result, the inside of the container is isolated from the external environment, allowing it to maintain the right temperature. A unique property of the containers, for storing samples is, patented unique technology, where liquid nitrogen is located only in the walls of the container and remains in complete isolation from the stored samples. This significantly improves user safety and minimizes the risk of sample contamination. Liquid nitrogen containers maintain a temperature of -190ºC to -195ºC throughout the storage chamber and tank shell. The liquid nitrogen is contained only in the walls of the container and remains completely isolated from the stored samples, which reduces the risk of contamination.
