Cryogenic Freezers (-150°C to -152°C) Cryogenic freezers for long-term preservation

High-Performance Cryogenic Freezers for Long-Term Sample Preservation

PHCbi Cryogenic freezers are specifically designed to achieve and maintain ultra low temperatures down to -150°C and -152°C depending on the model, enabling the long-term preservation of biological samples containing living cells. They are ideally suited for storing highly sensitive materials such as embryos, ova, stem cells, mammalian tissues, plasma components including blood cells, as well as plant cells and seeds.

In laboratory and research environments, safe and reliable cryogenic sample storage is essential. PHCbi’s cryogenic freezers are designed to provide optimal storage conditions for biological samples, pharmaceuticals, and other research materials at ultra-low temperatures. Advanced temperature control technologies help maintain stable storage conditions, safeguard sample integrity, reduce operating costs, and support consistent, high-quality research outcomes.

High-Performance Temperature Regulation for Sensitive Sample Storage

Biological samples, pharmaceuticals, and other research materials are highly sensitive to temperature variations. Accurate and stable temperature regulation is therefore essential for secure long-term storage and sample integrity. PHCbi developed the world’s first -152°C ultra-low temperature freezer in 1991, responding to the growing demand for cryopreservation driven by advances such as IVF and stem cell transplantation.

Since then, PHCbi has continuously invested in cryogenic freezer development, introducing improved insulation, advanced refrigeration technologies, enhanced alarm systems, and increased storage capacity. The latest PHCbi cryogenic freezers models deliver reliable temperature uniformity, sample protection, and operational efficiency supported by decades of specialist expertise in ultra-low temperature preservation.

Benefits of PHCbi Cryogenic Freezers

PHCbi Cryogenic ULT freezers are engineered to maintain precise ultra-low temperatures with rapid temperature recovery, helping protect valuable biological samples. Mechanical refrigeration provides a convenient alternative to liquid nitrogen-based storage while also allowing LN₂ backup where required.

Consistent Temperature Control for valuable samples

A high-stage cascade condenser and low-stage tube-on-sheet evaporator ensure even cooling throughout the chamber, preventing temperature fluctuations that could compromise sample integrity.

High-performance insulation and precision cooling

Patented VIP Plus vacuum insulation panels provide outstanding thermal efficiency, maximize usable storage volume, and reduce energy consumption within a compact footprint.

Energy efficient technology for low operating costs       

Advanced insulation and optimized refrigeration processes help reduce power consumption, supporting lower operating costs and reduced environmental impact over the freezer's operating life.

Reliable monitoring and safety features

Integrated monitoring and alarm systems—including temperature, power failure, and door status alerts—ensure immediate notification of any abnormal conditions, helping laboratories respond quickly and protect valuable samples.
