Ultra-Low Temperature Freezer (-86°C)

An Ultra-Low Temperature (ULT) Freezer (-86°C) is a specialized laboratory appliance designed to provide stable, deep-freezing conditions—typically ranging from -40°C to -86°C—for the long-term preservation of critical biological and chemical samples.

Key Features & Specifications

• Temperature Range: Operates steadily between -40°C and -86°C.
• Capacity Options: Available in various sizes, ranging from compact benchtop or 3-cubic-foot units to large upright or chest cabinets holding 100 to over 800 liters.
• Construction & Insulation: Built with high-strength cold-rolled or steel exteriors, 304 stainless steel interiors, and high-density vacuum insulation panels (VIP) or polyurethane foam to minimize thermal loss.
• Refrigeration System: Utilizes dual-compressor cascade or eco-friendly hydrocarbon systems for rapid cooling and fast temperature recovery after door openings.
• Control & Safety: Equipped with digital or touch-screen microcomputer controllers, battery backups for display/alarms during power outages, pressure balance valves, and multi-level security access.

Common Applications

• Clinical & Research Labs: Storing DNA, RNA, viral strains, enzymes, cell lines, and tissue samples.
• Medical & Vaccine Storage: Preserving temperature-sensitive pharmaceuticals and vaccines (such as mRNA COVID-19 formulations).
• Biobanks & Blood Banks: Maintaining long-term integrity for high-value or irreplaceable research specimens.
