Ultra-Low Freezers

In biomedical research, pharmaceutical production, and clinical laboratories, Ultra-Low Freezers (ULT freezers) are critical pieces of equipment for the storage of precious biological specimens. While standard laboratory freezers reach –20 °C, ultra-low freezers reach as low as –86 °C. This extreme cold preserves the long-term integrity of DNA, RNA, proteins, vaccines, enzymes, blood plasma, and other sensitive specimens.

At Medidepot.com, we provide a carefully selected selection of Ultra-Low Freezers from leading manufacturers such as Arctiko and Migali Scientific. Our products range from compact benchtop freezers for single workstations to large upright freezers accommodating hundreds of samples in biobank centers. Whether you are responsible for a small laboratory or an enormous research institute, our selection includes a model that meets your storage capacity, power usage, and dependability needs.

Why Ultra-Low Freezers are Needed

1. Biological Integrity Maintenance

Many biomolecules degrade quickly under standard freezer temperature. For example, RNA will begin degrading quickly if not stored in ultra-cold temperatures. By maintaining a stable range of –40 °C to –86 °C, ultra-low freezers provide a guarantee that samples remain viable for several years.

2. Reliable and Stable Cooling

Modern ULT freezers are built to ensure uniform temperature distribution. This minimizes the potential for hot spots in which samples might be compromised. Consistency across the entire cabinet is critical in laboratories where every vial, plate, or cryobox matters.

3. Energy Efficiency

Though ultra-low freezers use considerable amounts of power to achieve such low temperatures, contemporary machines are designed with twin compressors, inverter technology, vacuum insulation panels, and environmentally friendly refrigerants. These innovations minimize operating costs and environmental impact while guaranteeing sample safety.

4. Security and Peace of Mind

Many ULT models nowadays come with redundant cooling systems and alarm alerts. If one compressor should break down, the second system takes over to create a secure environment. This is a comforting feature that guarantees even in the event of unexpected failures, your precious samples are secure.

Types of Ultra-Low Freezers

1. Upright Ultra-Low Freezers

• Ideal for labs where instant accessibility and neat storage space are needed.
• Shelving and drawer units allow easy categorization of samples.
• An excellent choice for medium to large research centers.

2. Chest Ultra-Low Freezers

• Offer excellent cold retention from the horizontal lid construction.
• Typically more energy conserving, but occupy more floor area and necessitate bending for access.
• Best suited to facilities that value long-term stability over easy access.

3. Benchtop and Undercounter Ultra-Low Freezers

• Compact and space-saving designs that are suited for tiny labs.
• Can be mounted above or below workbenches for speedy sample access.
• Best for single researchers or clinical stations with very little space.

Frequently Asked Questions

Q: At what temperature do ultra-low freezers work?

A: They typically range from –40 °C to –86 °C, but most are at –80 °C.

Q: How is an upright different from a chest ULT freezer?

A: Chest units provide efficient shelving and rapid access, but upright units are more energy-efficient and effective at keeping things cold. 

Q: How long can samples be stored in a ULT freezer?

A: Sealed properly, samples may be maintained stable for decades or years at –80 °C.

Q: Are ULT freezers power hungry?

A: Yes, but they are much reduced by newer units using inverter compressors, dual systems, and green refrigerants.

Q: Which model is best for small labs?

A: The Arctiko ULUF P65 MV or the ULUF 125 are wonderful space-saving choices.
