Ultra-Low Temperature Freezers (ULT Freezers)

Ultra-Low Temperature Freezers (ULT Freezers) are specialized cold storage units designed to maintain temperatures between -40°C and -86°C, providing optimal long-term preservation of biological samples, vaccines, enzymes, tissue, DNA/RNA, and other sensitive materials. These freezers are essential in biobanks, pharmaceutical labs, hospitals, and research facilities where temperature precision and sample integrity are critical.


Our ULT freezers deliver uniform ultra-low temperatures with advanced insulation, microprocessor-based controls, and high-efficiency compressors. They feature safety systems including over-temperature alarms, backup battery monitors, and password-protected access to ensure security and compliance.


Available in upright and chest configurations, our models meet various storage capacity and space requirements. Whether for medical research, life science, or clinical applications, our ultra-low freezers ensure sample stability and regulatory compliance, even in the most demanding laboratory environments.
