150℃ Freezer 138L 226L
Ultra-low temperature freezer offering -150°C storage capability in 138L or 226L capacity configurations for reliable preservation of biological samples and temperature-sensitive materials.
| Automation Level | manual |
The 150°C Freezer provides ultra-low temperature storage for biological samples, reagents, and materials requiring preservation at temperatures down to -150°C. This compact unit offers dual capacity options of 138L or 226L storage volume, designed for laboratory environments where space efficiency and reliable temperature control are essential. The freezer utilizes advanced cooling technology to maintain consistent ultra-low temperatures, preventing thermal fluctuations that can compromise sample integrity.
Constructed with laboratory-grade materials and insulation, this unit supports long-term storage protocols for biospecimens, cell cultures, enzymes, and other temperature-sensitive materials. The compact footprint (50 x 63 x 44 cm) allows placement in standard laboratory spaces while providing sufficient capacity for routine research operations. Temperature uniformity and stability characteristics support applications requiring strict temperature maintenance over extended storage periods.
How It Works
Ultra-low temperature freezers operate through multi-stage refrigeration systems that achieve temperatures significantly below conventional freezing points. The cooling mechanism typically employs cascade refrigeration or specialized refrigerants capable of reaching -150°C operating temperatures. Thermal insulation systems minimize heat transfer from ambient conditions, while temperature control systems maintain precise thermal regulation within the storage chamber.
The freezing process at ultra-low temperatures causes rapid crystallization of water within biological samples, forming smaller ice crystals that cause less cellular damage compared to slower freezing methods. At -150°C, molecular motion is significantly reduced, effectively halting enzymatic activity and chemical reactions that could degrade stored materials. The controlled cooling rate and stable temperature maintenance prevent thermal cycling that can compromise sample integrity through repeated freeze-thaw effects.

Practical Tips
Verify temperature accuracy using multiple calibrated temperature probes placed throughout the storage volume.
Why: Ensures uniform temperature distribution and validates storage conditions for regulatory documentation.
Clean condenser coils monthly and check door seal integrity during routine maintenance cycles.
Why: Prevents reduced cooling efficiency and temperature instability from accumulated debris or air leaks.
Pre-cool storage containers to ultra-low temperatures before sample loading to minimize thermal load.
Why: Reduces temperature recovery time and prevents thermal stress on previously stored samples.
Use appropriate personal protective equipment when handling materials at ultra-low temperatures.
Why: Prevents cold burns and frostbite injuries from direct contact with ultra-low temperature surfaces or samples.
Maintain continuous temperature logs and document any temperature excursions for sample integrity assessment.
Why: Provides traceability for regulatory compliance and enables evaluation of sample quality following temperature events.
Monitor power consumption patterns to identify potential refrigeration system performance issues.
Why: Early detection of cooling system problems prevents sample loss from temperature failure.
Organize samples with clear labeling system and inventory management to minimize door opening time.
