Protecting valuable biological materials requires reliable, ultra-low temperatures. While –80 °C freezers remain widely used for general biobanking and molecular biology samples, certain applications, including regenerative medicine, reproductive cells and advanced therapies, demand colder, more stable storage. Traditionally, cryogenic storage has meant liquid nitrogen (LN₂) tanks.

Today, cryogenic freezers achieve –150°C using advanced mechanical refrigeration technology, delivering the same deep-cold protection with greater safety, easier handling and integrated alarms.

What Are the Challenges of LN₂ Storage?

LN₂ tanks achieve extremely low temperatures (–196°C) and are trusted worldwide. However, they also bring significant limitations:

Logistical complexity → Continuous LN₂ supply contracts and refills.
Safety risks → Oxygen displacement, spills, and frostbite hazards.
Cross-contamination risk → LN₂ can seep into imperfectly sealed vials and transfer pathogens.
Limited monitoring → Alarms and data tracking often require additional systems.
Challenging access → Vapour clouds and submersion make sample handling cumbersome.

These drawbacks are driving many labs to seek safer, simpler alternatives.

Why Are Cryogenic Freezers a Safer Alternative?

Cryogenic freezers provide deep-cold storage at –140°C to –150°C, cold enough to preserve highly sensitive biological materials while avoiding the risks that come with LN₂ storage.

Key advantages include:

Standard alarm functions for reliable protection.
Plug-and-play operation, only needs a standard electrical connection.
Safer lab environment, free from cryogen handling hazards.
Lower contamination risk, as samples are stored in racks, not submerged in liquid.
Consistent uniform cooling across all shelves.
Rapid recovery after door openings.

How Does ARCTIKO’s True Dual™ Technology Add Extra Protection?

Unlike conventional cryogenic freezers that rely on a single cooling system, ARCTIKO’s True Dual™ Technology uses two fully independent cooling cycles.

If one system fails, the other maintains –130°C or lower.
Samples remain secure without emergency transfers.
Integrated alarms immediately alert staff to any fault.

This redundancy ensures uninterrupted protection for priceless materials, giving labs peace of mind even in the rare event of a system breakdown.

Which Cryogenic Freezers should you choose?

CRYO 230 → Large 233L chest model, designed for high-volume storage. Features include True Dual™ Technology, low energy consumption (-33.5 kWh/24h), optional LN₂ backup, noise-reduced design, filter-less construction, and a full set of alarms (visual, acoustic, power failure, high/low temperature, probe failure). An optional chart recorder is available.

CRYO 170 → Compact 171L chest model, offering the same advanced protection in a smaller form factor. Features include True Dual™ Technology, low energy consumption (-31.7 kWh/24h), optional LN₂ backup, noise-reduced design, filter-less construction, and a comprehensive set of alarms (visual, acoustic, power failure, high/low temperature, probe failure). An optional chart recorder is available.

Both models provide:

Optional chart recorder for documentation.

Stable –140°C to –150°C storage.

Uniform cooling with rapid recovery.

Standard alarms for critical events.

When Should You Choose Cryogenic Freezers Over LN₂ Tanks?

Both LN₂ tanks and cryogenic freezers have an important place in modern laboratories, but the choice depends on your priorities.

Liquid Nitrogen Tanks (–196°C)

How they work: Samples are stored submerged in LN₂ or in the vapour phase.
Best for: IVF clinics, stem cell banks, and a narrow range of cases where absolute maximum long-term stability is required.
Challenges: Continuous LN₂ deliveries, strict safety handling, and higher risk of contamination.

Cryogenic Freezers (–140°C to –150°C)

How they work: Advanced refrigeration maintains –150°C with uniform, stable cooling.
Best for: Biobanks, research labs and cell/gene therapy facilities that need reliable deep-cold storage, with greater safety, easier access, and built-in alarms.
Why they stand out: No LN₂ logistics, no handling hazards, no contamination risks, and added protection with ARCTIKO’s True Dual™ Technology.

Which should you choose?

LN₂ tanks remain relevant for a small set of highly specialised use cases.

But for most modern laboratories, cryogenic freezers are the safer, smarter, and more efficient choice.
With ARCTIKO’s CRYO 170 and CRYO 230, you gain reliable –150°C storage, True Dual™ protection, and full alarm security, without the risks and complications of LN₂.

Protect What Matters Most

Every sample represents years of investment and discovery. With ARCTIKO’s –150°C Cryogenic Freezers, strengthened by True Dual™ Technology, your materials are protected safely, reliably, and without the risks of LN₂.
