Ultra-Low Temperature Freezers

Ultra-Low Temperature Freezers for Reliable Storage of Samples

Dependable performance over the range of -40°C to -86°C

Ultra low temperature freezer models

YIP Plus vacuum insulation for ultra low freezers
Our -86°C laboratory freezers, also known as ultra-low temperature (ULT) freezers, have a field-proven history of reliability and uniformity. All PHCbi brand ultra-low freezers are designed to meet or exceed the requirements necessary for reliable, long-term storage of samples. Performance of all our -86°C freezers is measured by overall temperature, stability in high ambient settings, recovery following routine door openings and reproducibility of internal conditions in real-world settings.

Natural refrigerants minimize environmental impact without jeopardizing ultra-low temperature freezer performance. Download the VIP Series brochure to learn more.

ENERGY STAR Certified VIP ECO Series upright lab freezer

VIP ECO Series ULTs have earned a worldwide reputation for dependable performance in demanding environments where critical materials must be preserved for generations. They are engineered from the inside out to create and maintain precise temperatures for optimal storage and reliable operation. Next-generation engineering harnesses the power of inverter compressor technology to yield greater temperature uniformity. Reserve refrigeration power delivers fast temperature recovery following door openings.
The VIP ECO Series includes the VIP ECO SMART, our most advanced ultra-low temperature freezer to date and winner of the 2023 ISBER Outstanding New Product of the Year Award (model MDF-DU703VH/VHA-PA). The VIP ECO SMART combines next-generation engineering with SMART control technology to provide a ULT with industry-leading energy efficiency and enhanced security and operation. The VIP ECO SMART uses up to 30% less energy than other leading ENERGY STAR Certified freezers.1
The VIP ECO combines field-proven reliability, natural refrigerants, and innovative cabinet design to improve performance and to help achieve facility sustainability objectives. The series includes ENERGY STAR Certified upright models as well as energy-efficient and compact, chest models.
Natural refrigerants minimize environmental impact without compromising ultra-low temperature performance. VIP Plus insulation ensures exceptional insulation value with a compact footprint. Learn more about the added features and benefits of the VIP ECO.

EZlatch Door Handle
When opening, the handle gently pushes the door away from the face of the cabinet. When closing, it evenly draws the door to the cabinet face against the multi-point gaskets. Download the VIP Series brochure to learn more.

VIP Series ultra low temperature freezer models

The PHCbi brand FrostLess upright freezer is engineered to mitigate frost buildup more than our category-leading ULT models while maintaining the reliability and energy efficiency that today's laboratories require.
The FrostLess ultra-low freezer uses an all-new thermal insulation design to reduce frost buildup on inner doors, reducing stress on the outer door and latch mechanism. This improves ULT freezer efficiency, and long-term performance, and reduces maintenance requirements while improving energy efficiency.
The PHCbi brand FrostLess ULT also uses the innovative door closure system, the EZlatch, designed to tolerate frequent door openings, simplify one-handed access, and control frost associated with extreme temperature differentials.

TwinGuard Dual Cooling System
The TwinGuard refrigeration system is comprised of two independent auto-cascade circuits managed by an electronic controller. Download the TwinGuard brochure to learn more.

TwinGuard Series ultra low temperature freezer models

TwinGuard Series ultra-low temperature freezers elevate the level of protection by using a redundant cooling system design which provides advanced protection of contents by functioning independently and simultaneously. Each cooling system uses single compressor auto-cascade configurations to provide uniformity and stability regardless of high ambient temperatures.
TwinGuard ultra-low freezers are designed for long-term storage of high value biologicals including mammalian and plant cell cultures, stem cells, cell lines and subcellular components. Learn more about TwinGuard Series ultra-low temperature freezers.
