Efficient cryopreservation with automatic liquid nitrogen freezers
AGA solutions make cryotechnology easier to use. We have designs suitable for many different media and storage temperatures. AGA offers the widest range of products on the market for storage of biological materials and the most advanced vacuum technology in the sector.
Our range includes liquid nitrogen deep freezers, liquid nitrogen cans and accessories. Thanks to our broad expertise, we can design and install "Turn Key" systems that enable efficient and the most economical use of liquid nitrogen and the best return on your storage investment.
Automated Liquid Nitrogen Freezers
AGA represents the world leading manufacturer of vacuum insulated products, Chart-Biomedical. MVE HE Series Automated Liquid Nitrogen Freezers where a temperature of -150°C or -190°C is maintained by circulating liquid nitrogen in the lower part of the device.
The samples are frozen in vapour phase not by immersing them in liquid nitrogen.
The devices are designed to maintain a steady temperature regardless of whether the biological materials are stored in liquid or vapour. One freezer can accommodate 15,600 to 94,500 biological sample vials, and the size of the freezer can be selected according to the customer’s storage requirements.
The Liquid Nitrogen Freezers are equipped with a TEC 3000 Control System. TEC 3000 employs a variety of advanced features that enable the controller to monitor the environment inside a freezer with a high level precision. Individual freezers can be equipped with a 230-litre storage tank, with automatic regulation of liquid nitrogen. For larger cryopreservation systems, liquid nitrogen is fed through vacuum-isolated pipelines from an external tank to the freezers.
Method advantages compared with electrical freezers
Liquid nitrogen freezers are reliable, take up less space, save on maintenance costs and are quieter. They can also attain lower temperatures than comparable electrical freezers.
Lower temperatures equal greater safety and a longer life for the samples. The devices also do not leak heat into the ambient air.
The high-power HE series uses 40% less nitrogen than standard devices with a similar volume. Every freezer is designed for optimum vacuum performance for duration of its use. Freezer structure enables samples to be stored in vapour. The storage temperature, -190°C in the MVE HE (High Efficiency) models, is the lowest on the market.
By choosing a liquid nitrogen freezer, you are installing a secure and viable environment free of noise and heat created by mechanical refrigeration system.
