Bonxrdun Lab Deep Freezer, 28L — -86°C
The Bonxrdun 28L deep freezer is designed for laboratory use with mobility in mind. It features a 565x550x785 mm footprint and wheels for easy movement without sacrificing performance. The interior is constructed from durable 304 stainless steel and offers a 28L capacity suitable for assorted samples. It reaches -86°C, supported by a German EBM condenser fan and an insulation layer 100 mm thick to maintain stable ultra-low temperatures.
Bonxrdun Lab Cryogenic Freezer, 20L — -86°C
This compact 20L unit is portable enough for one-person handling, measuring 78x51x41 cm and weighing around 46 pounds. It reaches -86°C (-122.8°F) to preserve sensitive specimens. The refrigeration system uses a copper tube fin-type air-cooled condenser and a low-temperature refrigerant mix that is free of fluorine, delivering fast cooling, strong heat dissipation, and extended service life.
Bonxrdun 50L Lab Freezer — -86°C
The 50L Bonxrdun model provides a larger storage capacity with a broad -86°C operating range. It features a 304 stainless steel interior for durability and easy cleaning, plus an EBM fan and a wrap-around copper coil condenser to promote rapid cooling and robust condensation management. This unit aligns well with research settings requiring higher sample throughput.
LABFENG -86°C 28L Freezer
LABFENG offers a compact 28L design with dual door gaskets and high-density polyurethane insulation to minimize heat ingress. A microcomputer control system with an LED digital display provides precise temperature readouts to 0.1°C. Its full copper tube evaporator and durable welded shell contribute to reliable long-term performance in laboratory environments.
Northair 3.5 Cu Ft Chest Freezer — 14°F to -40°F
Northair’s 3.5 cu ft chest freezer provides adjustable temperature control with a digital display, delivering a range from 14°F to -40°F. It offers easy storage with removable baskets and a compact footprint suitable for kitchens, small labs, or retail environments. Although not at -86°C, this unit supports ultra-low storage needs where ultra-cold temperatures are not mandatory for all materials.
Northair Black 3.5 Cu Ft Chest Freezer
This ProBlack edition mirrors the standard Northair chest freezer with triple-freeze technology for flavor and freshness preservation in food storage scenarios. It maintains 14°F to -40°F with a precise 1°F display. It’s best suited for environments needing efficient freezing with a compact footprint, quiet operation, and energy savings.
ADT Low Temperature Chest Freezer 3.5 Cu Ft
ADT’s chest freezer offers 3.5 cubic feet of storage with a wide temperature range from 14°F to -40°F. It emphasizes rapid freezing with a high-performance compressor, precise digital temperature control to 1°F, and a balance of energy efficiency and quiet operation, suitable for kitchens, offices, or small labs needing dependable low-temperature storage.
Buying Guide
Key considerations when selecting an ultra low temperature freezer:
- Temperature range and stability: Decide whether you need -86°C for cryogenic samples or a broader range for different material types. Pay attention to insulation thickness and condenser design, as these affect temperature stability and energy use.
- Capacity vs. footprint: Balance internal volume with available space. Consider whether mobility (wheels, lightweight design) is important for your lab layout or if a fixed unit suffices.
- Interior materials and hygiene: Stainless steel interiors are easier to clean and sanitize, which matters for biological samples and chemical applications.
- Power and maintenance: Look for reliable compressors, copper condensers, and protective features like door gaskets and electronic temperature controls. Assess noise levels and energy efficiency for sustained operation.
- Portability and installation: Countertop or compact units enable flexible deployment in shared spaces, while larger freezers suit dedicated labs. Ensure power requirements align with your facility’s electrical setup.
- Durability and warranty: For high-stakes storage, select models with robust construction and clear warranty terms to cover long-term use.
