Efficiency and safety through cryogenic technology
The use of cryogenic storage technology for storing biological materials has revolutionized medical research. With the introduction of liquid nitrogen freezers, the cryo-storage process has become more efficient, reliable, and cost-effective.
Linde offers innovative and efficient liquid and vapor-phase freezers designed to cover a range of storage temperatures from -20°C to -190°C.
Our advanced vacuum technology sets us apart from the competition. Our state-of-the-art equipment maintains consistent temperatures for optimal storage of biological materials.
We are proud to offer the widest range of products in the market suitable for biological material storage. From liquid nitrogen and vapor-phase freezers to dewars and storage accessories, Linde's range has everything you need.
With our extensive expertise, we can design and install turnkey systems that are efficient and cost-effective in the use of liquid nitrogen, providing you the best return on your storage investment.
Advantages of the method compared to electric freezers
Cryopreservation is the process of storing biological materials at very low temperatures. Mechanical freezers have traditionally been used in this process, but liquid nitrogen freezers have several advantages that make them more efficient and cost-effective than mechanical freezers.
● Liquid nitrogen freezers are reliable and bring huge savings in maintenance costs.
● When liquid nitrogen freezers are used, there is no noise or heat generated by mechanical freezers.
● The lower temperatures achievable with liquid nitrogen freezers increase safety and prolong the shelf life of samples. In the event of a power outage, liquid nitrogen maintains the desired temperature for up to two weeks.
● Each freezer is designed for optimal vacuum performance.
● The freezer's design allows for sample preservation in vapor or liquid phase.
Thanks to these advantages, researchers can rely on their biological materials to be stored optimally for long-term storage and future use.
Did you know?
● Nitrogen is an inert gas. It is stable - it does not form dangerous reactions with other substances.
● Liquid nitrogen (LIN) is colorless, odorless and tasteless. LIN is extremely cold, with a boiling point of -196 °C (-320 °F).
● When handling liquid nitrogen, precautions must be taken as it can cause cryogenic burns or injuries. Always use cold-insulating gloves and face shields.
● Suffocation hazard - lack of oxygen. Oxygen monitoring alarm system is required in areas where liquid nitrogen is used.
Automated liquid nitrogen freezers
Linde represents MVE Biological Solutions, the world's leading manufacturer of vacuum insulated products. The HeCo series -190 °C freezers are available in three sizes and offer maximum storage density of 15,600 - 94,500 biological sample vials. They are among the most efficient vapor phase freezers on the market. Features include:
● Storage of dry samples
● -190 °C top box temperature
● Efficient use of liquid nitrogen
● Safe storage time is about 2 weeks before the temperature rises from -190 °C to -130 °C after the latest fill.
● Automatic monitoring system with liquid level monitoring, temperature alarm and log
Individual freezers can be equipped with a 230 liter storage tank, which is automatically supplied with liquid nitrogen. In larger cryopreservation systems, liquid nitrogen is supplied to the freezers through vacuum-insulated pipelines from an external tank.
A new innovative and energy-efficient alternative to cryogenic storage at extremely low temperatures.
Together with Chart Bio Medical, Linde offers a completely dry sample storage freezer. It maintains the temperature defined by the user anywhere between -50 °C and -150 °C.
The MVE Variō series significantly reduces the possibility of sample contamination through contact with LN2, while also providing the safety margin and consistent temperature profile associated with LN2-based cryogenic storage, even with the cover open.
The MVE Variō series is capable of delivering all of this with less than 1% power consumption and about 70% total operating cost savings compared to leading mechanical freezers.

What do customers say?
"Another thing that is really important to us is the safety of storing samples. In the event of a power outage, we can keep the samples frozen for two weeks after the last liquid nitrogen refill, which would not be possible with electric freezers, from which samples usually need to be evacuated within 24 hours."
