Any workflow where a sample cannot warm up — in the hospital, in the vehicle, or hundreds of kilometres from the nearest mains socket.
Cell therapies, regenerative medicine products and autologous material lose viability if they drift above −60 °C. A portable ULT freezer keeps the product inside its validated range from the manufacturing suite to the treatment room, with logged temperature evidence for release.

Replace dry-ice replenishment with active cooling. Because the setpoint is adjustable in 1 °C steps, you can hold −70 °C, −80 °C or any other protocol temperature — and prove it with continuous monitoring rather than a manual log sheet.

Bring ultra-cold storage to the patient side. At 21 kg and under 55 dB(A), a 25 L unit sits quietly in a clinic or treatment room and runs from a normal wall socket — so therapy can be prepared and held exactly where it is administered.

Collect specimens far from infrastructure on 24 V DC vehicle power. There is no dry ice to source, no sublimation to plan around, and no CO₂ build-up inside a confined vehicle cabin — a real safety advantage for mobile collection teams.

Put a −86 °C unit beside the bench instead of walking samples to a shared upright freezer. Frees central capacity, shortens handling time and gives individual research groups control over their own storage conditions.

Simulate an ultra-cold environment to validate components, electronics, seals and polymers. The chamber holds a stable low temperature for extended soak tests without consuming liquid nitrogen.

Sample type, volume, ambient conditions, transport mode and power availability — that is enough for us to recommend a configuration and quote.
