Liquid Nitrogen Cryo Cart: A Mobile Workstation for Safe Sample Handling
Short answer: A liquid nitrogen cryo cart is a mobile, stainless steel cryogenic workstation that lets you handle and transport biological samples in the vapor phase above liquid nitrogen — without taking them out of the cold chain. Our cart holds 50 liters of LN2 under its work tray, provides over 24 hours of hold time, stores up to 3,000 2 ml cryovials, includes a temperature recorder, and rolls on braked casters.
In a biobank or cell therapy lab, the most dangerous moment for a sample is not storage. It is handling. Pull a cryovial out of a liquid nitrogen tank, carry it across the room to a bench, open it, sort it, log it, repackage it — and every second it spends in room-temperature air is a second its temperature climbs. Multiply that by dozens of samples per session, and the cumulative risk becomes real.
The liquid nitrogen cryo cart exists to remove that gap. It brings the cold to the work — instead of bringing the work to the cold.
What Is a Liquid Nitrogen Cryo Cart?
A liquid nitrogen cryo cart is a wheeled cryogenic workstation designed for sample operations and transport inside hospitals, sample banks, and laboratories. Rather than being a sealed storage tank, it is an open work platform: a liquid nitrogen reservoir sits beneath a work tray, and samples are handled in the cold vapor zone directly above it.
That open, working-height design is what separates it from a storage dewar. You can reach in, sort boxes, pick individual vials, verify labels, and repackage — all while the samples stay in a cold, stable environment.
Key Features of Our Liquid Nitrogen Cryo Cart
Over 24 hours of holding time
The cart is built with high-vacuum multilayer insulation and a lid made from aluminum alloy with insulating foam. Together, they keep liquid nitrogen loss low and maintain the cold zone for more than 24 hours — enough to cover a full working session, a shift change, or an overnight standby without sample risk.
Built-in temperature recorder
A temperature recorder is fitted as standard, so every session leaves an auditable temperature record. For biobanks and clinical facilities operating under quality management systems, that documentation is not optional — it is the evidence that your cold chain held.
CGA295 connection for easy connect and disconnect
The cart is equipped with a CGA295 fitting, making liquid nitrogen connection and disconnection straightforward and repeatable. Standard fittings mean standard procedures — faster refills and fewer adapter headaches.
Casters with brakes for safe movement and parking
The cart rolls on its own casters with built-in brakes. Move it between storage, processing, and packing areas, then lock it in place. Stable during work, easy to reposition between tasks — no lifting, no dragging.
Stainless steel body with insulated aluminum lid
The main body is made of high-quality stainless steel for corrosion resistance and easy cleaning. The aluminum alloy and foam lid keep the unit light to handle while actively limiting evaporation, which is what makes long working sessions practical.

FAQ
What is the difference between a cryo cart and a storage tank?
A storage tank keeps samples sealed and stored. A cryo cart is an open working platform that lets you handle samples in the cold vapor zone — designed for operations and transport, not long-term storage.
How long does the cart hold liquid nitrogen?
Over 24 hours, supported by high-vacuum multilayer insulation and the aluminum alloy foam lid.
Does it record temperature?
Yes. A temperature recorder is included as standard, providing documentation for each handling session.
How many samples can it hold?
Up to 3,000 2 ml internally threaded cryovials, or 65 × 5×5 cryoboxes, 30 × 10×10 cryoboxes, 105 × 50 ml blood bag boxes, or 50 × 200 ml blood bag boxes.
Is it easy to move?
Yes. It has brakes and casters, so you can move it between work areas and lock it in place during operation.
Conclusion: Bring the Cold to the Work
Sample integrity is not only about how well you store. It is about how carefully you handle — and a liquid nitrogen cryo cart turns that handling into a controlled, documented, cold-chain-safe activity.
Our liquid nitrogen cryo cart combines a stainless steel body, high-vacuum multilayer insulation, 50 liters of LN2 capacity under the work tray, over 24 hours of hold time, a built-in temperature recorder, a CGA295 connection, and braked casters — a complete mobile workstation for biobanks, hospitals, cell therapy facilities and research labs.
