Bonxrdun Lab Cryogenic Freezer, -86°C, 20L
The Bonxrdun -86°C lab freezer combines portable design with robust cooling performance. Its compact dimensions (approximately 78x51x41 cm) and a weight of about 46 pounds enable convenient transport within a laboratory or between field sites. It reaches -86°C (-122.8°F) to preserve ultra-sensitive samples and uses an environmentally friendly refrigerant, supported by a copper tube fin-type air-cooled condenser for efficient heat dissipation. The unit emphasizes fast cooling and long service life, suitable for research settings needing reliable ultra-low storage in a portable package.
-86°C Ultra-Low Temperature Freezer, 50L
LABFENG’s 50L ultra-low freezer delivers -86°C (-123°F) with dual-door gaskets and high-density insulation. Its microcomputer control system provides 0.1°C accuracy on an LED display, enabling precise monitoring. A full copper tube evaporator and durable construction ensure stable performance and resistance to corrosion. The design supports reliable long-term sample preservation, with a focus on minimizing temperature fluctuations in a mid-sized laboratory environment.
Donpemu 25L Ultra-Low Temperature Freezer
Donpemu offers a compact 25L unit designed for versatile lab use, delivering -86°C/-122.8°F with dual doors and high-density insulation to minimize cooling losses. The microcomputer system provides a 0.1°C display and customizable temperature alarms for reliable monitoring. Its galvanized steel body, copper evaporator, and lightweight construction enable easy relocation in busy labs or fieldwork scenarios.
-86°C Ultra-Low Temperature Freezer, 28L
LABFENG’s 28L unit provides compact ULT storage with dual gaskets and rigid insulation to reduce thermal loss. A microcomputer control system with a 0.1°C precision LED display ensures accurate monitoring, while a full copper tube refrigeration system and sturdy construction promote durability and long-term reliability in a laboratory setting requiring frequent access to small-volume samples.
ARLUMA Ultra Low Temperature Freezer, 25L
ARLUMA’s 25L ULT freezer features a professional range of -86°C (-123°F) with a smart alarm system and adjustable temperature control. Its compact footprint suits benchtop or small lab setups, and the double-door lock design helps protect sensitive items. The unit emphasizes precise digital control, secure storage, and portable usability for researchers needing dependable, compact ultra-low temperature storage.
Buying Guide
- Temperature range and stability: Look for units that consistently achieve -86°C or lower and offer precise control (±0.1°C where possible) to protect sensitive samples.
- Capacity versus footprint: Balance storage needs with space constraints. Smaller 20–28 L models suit compact labs, while 50 L units provide more room for larger inventories.
- Insulation and seals: Dual-door gaskets and high-density foam help minimize thermal loss and energy usage, especially in open lab environments.
- Control systems: Microcomputer or digital displays with alarms (audio/visual) improve monitoring and reduce risk of temperature excursions.
- Construction and durability: Copper tube systems, corrosion-resistant shells, and robust hinges contribute to long-term reliability in busy labs.
- Portability and installation: Evaluate weight, handles, and whether the freezer can be moved between locations without compromising performance.
- Safety features: Locks, double-door designs, and secure access help protect stored specimens and maintain compliance with handling protocols.
- Energy efficiency: Energy consumption varies; units with efficient condensers and insulated walls reduce operating costs over time.
- Maintenance considerations: Access to replacement parts, ease of cleaning, and service availability are important for ongoing operation.
- Compliance and compatibility: Ensure the unit meets applicable standards for research or clinical storage and fits with existing lab workflows.
