Ultra-Low Temperature Freezer: Professional Ultra-Cold Storage for Scientific and Lab Needs
Dec
Storing sensitive biological samples requires equipment that can maintain extremely low temperatures with precision. An Ultra-Low Temperature Freezer (–86°C Freezer) provides a stable, ultra-cold environment to keep scientific, medical, and research materials safe for months or even years.
Caresource, a trusted supplier and distributor of scientific and laboratory equipment across UAE, Saudi Arabia, Qatar, Oman, Bahrain, Kuwait, Africa, the Philippines, and more, offers high-quality ultra-low freezers designed for long-term reliability and precise sample preservation.
What Is an Ultra-Low Temperature Freezer?
An Ultra-Low Temperature (ULT) Freezer, commonly called a –86°C Freezer, is a specialized refrigeration system used for storing:
- Virus and bacterial strains
- DNA and RNA
- Tissues and cell cultures
- Enzymes and protein samples
- Vaccines and pharmaceuticals
- Plasma and clinical samples
- Long-term research specimens
The freezer maintains temperatures between –40°C and –86°C, halting biological activity and preventing sample degradation. This makes it essential for research, clinical, and industrial laboratories.
Why It’s Different From Standard Freezers
A ULT freezer is more advanced than standard laboratory or household freezers because it:
- Maintains ultra-low temperatures consistently
- Provides uniform cooling throughout the chamber
- Uses dual compressors and advanced insulation
- Reduces temperature fluctuations when the door is opened
- Includes built-in safety systems to protect valuable samples
These features ensure long-term sample integrity and precise experimental conditions.
How an Ultra-Low Temperature Freezer Works
ULT freezers combine advanced cooling technology with smart temperature management.
1. Dual-Stage Cooling System
- Stage 1: Precools to an intermediate temperature.
- Stage 2: Lowers the chamber to –86°C for ultra-cold storage.
2. High-Density Insulation
Thick polyurethane foam prevents heat from entering and maintains consistent ultra-low temperatures.
3. Smart Microprocessor Control
Monitors temperature continuously, adjusts compressor performance, displays conditions, and triggers alarms if needed.
4. Even Air Circulation
Cold air is distributed uniformly to prevent temperature variations across shelves and racks.
5. Safety Features
Sensors and alarms protect samples from unexpected temperature changes, power failures, or door openings.
Key Features and Benefits
Ultra-Low Temperature Range
Operates from –40°C to –86°C, ideal for sensitive biological and medical materials.
Fast Cooling Recovery
Quickly returns to the set temperature after door openings, minimizing sample exposure.
Stable Internal Temperature
Ensures even cooling across all shelves and racks.
Multi-Level Alarm System
Alerts for over-temperature, power failure, and door-open events to safeguard samples.
Energy-Efficient Operation
Dual compressors and eco-friendly refrigerants lower energy consumption while maintaining ultra-cold conditions.
User-Friendly Digital Controls
Intuitive interface for precise temperature management and monitoring.
High-Strength Door Seal
A tight gasket reduces frost and maintains stable internal temperature.
Supported Storage Options
Ultra-low freezers can store a variety of lab materials:
- Cryo boxes
- Research vials and tubes
- Cryovials
- Tissue containers
- Ampoules
- Adjustable racks and storage drawers
This flexibility allows laboratories to organize samples efficiently.
