Stirling Ultracold SU780XLE Ultra-Low Temperature (-80°C) Freezer with 780L Capacity

The Stirling Ultracold SU780XLE is a high-performance ultra-low temperature freezer designed for long-term sample storage in biotechnology and clinical diagnostics. Utilizing a proprietary free-piston Stirling engine with ethane refrigerant, it achieves temperatures from -20 °C to -86 °C without a traditional compressor, enabling 70-75% energy savings compared to standard ULT freezers. This freezer cools from ambient temperature to -80 °C in under 6.5 hours and recovers target temperature within 35 minutes after door openings, making it ideal for workflows requiring rapid temperature stabilization.

Key technical features include:

• Storage volume: 780 liters (27.5 cu. ft.) capacity supporting up to 600 standard 2 ml cryogenic storage boxes, optimized for biomanufacturing and molecular diagnostics sample organization.
• Noise level: Advanced noise abatement technology limits operational noise to below 45 dB(A), suitable for laboratory environments.
• Ambient operating range: Robust performance between +5ºC and +35ºC, accommodating diverse laboratory conditions.
• Microprocessor control: Secure touchscreen panel with optional PIN access, graphical interface for precise temperature setting (1ºC increments), alarm control, and a 30-day graphical event log for compliance in regulated biotechnology workflows.
• Physical dimensions: Interior space of 28x26x58 inches; exterior dimensions 35x40x78 inches; weighing 800 lbs.
• Power specifications: Operates on 100-240V, 50/60Hz using 1200 watts power with current draw of 10 amps at 120V or 5 amps at 240V.
• Enhanced security: Lockable door and battery backup lasting 12 hours for touchscreen operation ensures data integrity and sample protection during power outages.

The SU780XLE is widely adopted in synthetic biology research, bioprocessing pipelines, and molecular cloning workflows where energy efficiency, environmental sustainability, and reliable -80°C storage are critical. Its large capacity and rapid temperature recovery support demanding applications in live-cell imaging sample preservation and biopharmaceutical production.

This model meets the needs of researchers and laboratory managers seeking a sustainable ultra-low temperature solution that reduces carbon footprint without compromising sample integrity or operational efficiency.
