Accucold AULT50PSR12 1.8 Cu.Ft. -86ºC Ultra Low Upright Freezer for Biological Sample Storage

The Accucold AULT50PSR12 is a precision-engineered ultra low temperature (ULT) upright freezer designed for long-term storage of sensitive biological materials, DNA/RNA samples, vaccines, and pharmaceuticals. Offering 1.8 cubic feet (51 L) of capacity, this unit operates within a -86ºC to -40ºC temperature range and is optimized to maintain ±3ºC stability from the set point, critical for molecular diagnostics and bioprocessing applications.

Key technical features include:

• Advanced microprocessor digital control panel enabling precise temperature management and USB data logging every 5 minutes for up to 10 years, facilitating compliance with GLP/GMP documentation requirements.
• VIP vacuum insulation panel (VIP) and an insulated inner door for enhanced thermal retention and energy efficiency, accelerating temperature pulldown to -80ºC within 185 minutes and rapid recovery within 24 minutes after door openings.
• Durable steel interior with adjustable shelves capable of holding two racks accommodating up to 36 standard 2-inch freezer boxes, supporting common sample storage formats used in synthetic biology and molecular cloning workflows.
• Comprehensive audible and visual alarm system monitoring interior and ambient temperature fluctuations, door ajar warnings, power outages, and multiple sensor alerts to ensure sample integrity in clinical diagnostics and biotechnology research.
• Ergonomic side-mounted handle with built-in keyed lock allowing for secure storage, along with pre-installed casters (two locking) for mobility in busy lab environments.
• Equipped with an access port for integration of additional temperature or environmental monitoring probes, suitable for advanced biomanufacturing quality control setups.
• Powered by an energy-efficient auto cascade compressor (1045 BTU) using an eco-friendly hydrocarbon refrigerant, compliant with CARB regulations, aligning with sustainability practices in laboratory infrastructure.
• Dimensions: 30.25" H x 37.63" W x 26.38" D (cabinet), with a quiet operational noise level of 54.3 dB to maintain undisturbed lab conditions.

The AULT50PSR12 is UL and ULC listed for North American safety standards and includes a comprehensive 12-year compressor and 5-year parts and labor warranty, underscoring its reliability in demanding research and clinical environments. This ultra low freezer is widely adopted in synthetic biology research, biopharmaceutical production pipelines, and essential for molecular cloning workflows requiring strict cold chain management.
