Cryogenic storage tanks are essential for safely storing biological samples, gases, and other materials at extremely low temperatures. These tanks are widely used in medical research, biotechnology, pharmaceuticals, and industrial applications where maintaining sample integrity is critical. Selecting the right cryogenic storage tank involves considering factors such as temperature stability, capacity, safety, and ease of use. This guide provides an overview of different types of cryogenic storage tanks, key features to consider, and a price guide to help you make an informed decision.

Liquid Nitrogen Storage Tanks are designed to store and handle liquid nitrogen (LN2), which is commonly used for freezing and preserving biological samples. These tanks are equipped with insulated walls to maintain the ultra-low temperature required for sample preservation. They are available in various sizes, from small portable units to large stationary tanks.
Applications: Biobanking, sperm and egg storage, cryopreservation of biological samples, and industrial cooling.
Liquid Oxygen Storage Tanks are used to store and transport liquid oxygen (LOX) at cryogenic temperatures. These tanks are commonly used in medical facilities, laboratories, and industrial settings. The tanks are equipped with safety features to handle the pressurized nature of liquid oxygen safely.
Applications: Medical oxygen supply, industrial processes, aerospace, and scientific research.
Liquid Argon Storage Tanks store liquid argon (LAr) for various applications, including welding, metal fabrication, and semiconductor manufacturing. Liquid argon is also used in research laboratories for its inert properties, which prevent chemical reactions.
Applications: Welding and metal fabrication, semiconductor manufacturing, and scientific research.
Liquid Helium Storage Tanks are used to store liquid helium, which is essential for applications requiring extremely low temperatures, such as superconducting magnets and cryogenic research. Helium is also used for cooling purposes in MRI machines and other advanced medical equipment.
Applications: MRI cooling, cryogenic research, superconducting magnets, and space exploration.
Dewar Flasks are specialized containers designed for the temporary storage and transportation of cryogenic liquids. These flasks are portable and feature double-walled vacuum insulation to minimize heat transfer. They are ideal for applications requiring smaller quantities of cryogenic fluids.
Applications: Laboratory use, cryogenic liquid handling, short-term storage, and transportation of liquid nitrogen or helium.
Bulk Cryogenic Storage Tanks are large-capacity tanks designed for the storage and supply of cryogenic liquids in industrial settings. These tanks are constructed with robust materials and are equipped with advanced insulation to maintain the desired temperature. They are suitable for high-demand applications.
Applications: Large-scale industrial processes, chemical manufacturing, gas distribution, and medical facilities.
Maintaining consistent ultra-low temperatures is critical for the preservation of sensitive samples and materials. Choose tanks with high-quality insulation and temperature stability to ensure the integrity of the stored contents. Vacuum insulation and multi-layer insulation are commonly used to minimize heat transfer.
Consider the capacity requirements of your application when selecting a cryogenic storage tank. Tanks are available in a range of sizes, from small portable models to large industrial tanks. Ensure the tank can accommodate the volume of cryogenic liquid needed for your specific needs.
Cryogenic storage tanks must be constructed from materials that can withstand extreme cold and resist corrosion. Stainless steel and aluminum are commonly used materials for their durability and strength. Ensure the tank meets industry standards for quality and safety.
Safety is paramount when handling cryogenic liquids, which can cause severe burns and pose explosion risks if not properly managed. Look for tanks with pressure relief valves, safety vents, and secure locking mechanisms. Automated monitoring systems can provide real-time alerts for temperature and pressure changes.

Consider the ease of use and handling features of the cryogenic storage tank. Tanks with ergonomic designs, easy-to-read gauges, and convenient access points for filling and dispensing cryogenic liquids improve user experience and safety. Mobility features, such as wheels or handles, can enhance portability.
Regular maintenance is essential for the safe operation of cryogenic storage tanks. Choose tanks with accessible components for easy cleaning and inspection. Availability of technical support and service plans can ensure your tank remains operational and effective over time.
Cryogenic tanks are an optimal solution in cases where large quantities of gas need to be stored in liquid form, such as Liquid Oxygen, Liquid Nitrogen, Argon, C02, LNG, LPG, Liquid Hydrogen, etc.
Cryogenic tanks are a type of industrial storage tank boasting a range of strengths, related to aspects such as internal distribution, loading and safety.

Cryogenic tanks are very versatile, allowing for the installation of a centralised network for the optimal distribution of the different cryogenic gases used. An important advantage of this type of tank is that there is no gas return to the plant, as is the case with other systems such as cylinders. It goes without saying that this translates into resources saved.
The loading of the gases into the cryogenic tanks is done using vaporisers. The major benefit of this system is that the liquid gas passes directly from the production plant to the user, avoiding sudden movements and improving stability and safety.
The gas stored in cryogenic tanks maintains a higher level of purity than in other storage systems, as it always remains isolated in a hermetically sealed tank meaning that no possibility exists of contamination with any external agents.
Risks are kept to a minimum, as the gas remains isolated in hermetically sealed, stable tanks with no contact with the outside world. Cylinder transfer within the facilities is avoided, avoiding unnecessary hazards.
A cryogenic tank is composed of a structure divided into two fundamental parts:
The two vessels are insulated from each other by a combination of insulating materials.
In addition to these two containers separated by insulating material, cryogenic tanks are equipped with another vital component: a pressure regulation system. This system is specifically designed to ensure that the cryogenic tank always operates at a constant pressure that is set with the user&#;s needs in mind.
Tanks for storing cryogenic gases follow very strict safety requirements and protocols, in order to avoid any type of accident that may cause leaks, material damage and, above all, personal injury. Here are some of the main safety measures:
A huge variety of cryogenic tanks exists, each perfectly adapted to the cryogenic liquid they have to hold, as well as to where they are going to be located: size, place, terrain, etc.
Cryogenic tanks will therefore have different shape and design characteristics depending on whether they contain:
