Purpose-Built Cold Chain Storage

PHCbi brand biomedical freezers are engineered from the inside out to create, maintain and restore precise temperatures necessary for vaccine storage. Our purpose-built -30°C to -40°C vaccine storage freezers are designed for temperature uniformity and stability that is not commonly found with household or commercial cabinets. PHCbi brand vaccine cold chain storage solutions satisfy current and evolving storage protocols essential for continued vaccine efficacy.

Optimum Storage Capabilities

PHCbi biomedical freezers offer auto defrost storage solutions for uniformity, reliability and environmentally safe operation. This upright medical-grade and laboratory grade freezer provides storage at -30°C with electronically controlled auto-defrost, which occurs only on demand. It leads to minimized temperature spikes and maintenance-free storage. No need for end user intervention to defrost unit and clean up condensate.

Optimized Design and High Performance

Constructed with high performance laboratory and clinical grade refrigeration systems, these high performance biomedical freezers are used in clinical, biotechnology and industrial labs. Unlike many other cold wall freezers, the High Performance Biomedical Freezers Series has cooling coils strategically spaced in the walls, along both sides, the back, the top and the bottom of the chamber to ensure maximum cooling performance.

Superior Temperature Uniformity

The robust refrigeration system, powered by PHCbi compressors, provides dependable cooling by balancing temperature performance and energy management.

Microprocessor Controller and Alarms

Comprehensive setpoint, alarm, monitoring and diagnostic functions are maintained by PHC-built microprocessor controller with digital display of all input/output function.




-30°C Upright Laboratory Grade Freezer

PHCbi High Performance Biomedical Freezers are designed for short- or intermediate-term storage at temperatures as low as -30°C. Constructed with high performance laboratory and clinical grade refrigeration systems, these freezers are used in medical, biotechnology and industrial labs for storage of blood components, enzymes, culture media, reagents, specimens and vaccines.

The MDF-U731-PA -30°C Upright, Medical-Grade Freezer was designed with the features to give superior uniformity, microprocessor control and large storage capacity. Two access ports, casters, remote alarm contacts and security features are included as standard features.
