Liquid Nitrogen (LN2) and Cryogenics

High-Performance Cryogenic Freezers & Sample Storage Equipment

What is a Mechanical Cryogenic Freezer?

A mechanical cryogenic freezer is a specialized ultra-low temperature storage unit, ideal for preserving sensitive biological samples such as cells, tissues, and enzymes over extended periods. Unlike traditional cryogenic systems that rely on liquid nitrogen, mechanical cryogenic freezers use advanced compressor technology to reach ultra-low temperatures without requiring LN2. At Laboratory Equipment Company, we provide these freezers as a safer, more manageable solution for labs that demand dependable, long-term sample preservation.

How Does a Mechanical Cryogenic Freezer Work?

Mechanical cryogenic freezers use a dual compressor, auto-cascade compressor system to achieve extremely low temperatures, reaching storage temperatures of -150°C or lower. A well-designed system will incorporate a liquid nitrogen back-up system to offer further protection in the event of an electrical outage. A -150°C mechanical freezer ensures uniform, consistent, and stable cooling critical for long-term storage of delicate samples. For facilities prioritizing total automation, automated robotic cryogenic LN2 storage systems offer high-density sample retrieval with minimal human thermal exposure.

What are the Advantages of a Cryogenic Freezer?

Mechanical cryogenic freezers offer significant benefits, including uniform, consistent ultra-low temperatures without the need for dangerous liquid nitrogen (LN2) handling, improved user safety, and simplified storage management with no LN2 dripping on the floor. Available in a chest style, these freezers also come with advanced monitoring features. Facilities requiring off-site transport or manual vapor phase storage can also utilize cryogenic shippers and liquid nitrogen transport to maintain cold chain security without mechanical power.

Is Cryogenic Freezing Safe to Use?

Mechanical cryogenic freezers typically operate around -150°C, which is below the glass transition temperature essential for preserving biological materials in a stable environment for the long term. For specialized high-volume liquid storage, facilities often connect their freezer setups directly to bulk liquid nitrogen cylinders and supply tanks to maintain continuous liquid feed capabilities. Laboratory Equipment Company offers a selection of high-performance freezers that deliver reliable, precise cooling offering superior performance and quality of cold to support your critical research and sample storage needs.
