Some things don’t get a second chance. Your samples are one of them.

Embryos. Stem cells. Cord blood. Semen. Tissue biopsies. The moment these leave your facility, they enter a window of vulnerability that most people don’t think about until something goes wrong. A dry shipper that sweats, loses hold time ahead of schedule, or arrives off temperature doesn’t just fail a quality check it can end a patient’s last viable attempt at IVF. It can invalidate years of research. It can cost a biobank its accreditation.

That’s exactly the problem the CryoStork dry shipper was designed to solve.

What Is a Dry Shipper and Why Does It Matter More Than You Think?

A dry shipper is a cryogenic container that uses liquid nitrogen (LN2) to maintain ultra-low temperatures during transport typically between -150°C and -196°C without the liquid nitrogen being in free-standing form inside the container. Instead, the LN2 is absorbed into a specially engineered sorbent material inside the dry shipper container walls.

With a standard liquid nitrogen tank or dewar, free LN2 is present meaning it’s classified as a dangerous good for air freight, subject to IATA regulations, restricted by most airlines, and frankly a nightmare to ship internationally. A true dry shipper? No free liquid. No hazmat. No airline drama.

But here’s what most dry shipper guides don’t tell you: not all dry shippers are built equal, and the difference between budget and precision engineered becomes visible the moment your shipment gets delayed, left on a hot tarmac, or handled by a courier who has no idea what they’re carrying.

Introducing the CryoStork Cryolab’s Precision Dry Shipper

CryoStork isn’t a catalogue product with a Cryolab sticker on it. It’s a dry shipper dewar engineered from the ground up for clinical, research, and biobanking environments where sample integrity is non-negotiable.

Here’s what makes it different:

Extended Hold Time Built for Real-World Logistics

Real shipping doesn’t always go to plan. Customs delays. Missed connections. Quarantine holds. CryoStork is built with industry-leading static hold time so that even when the unexpected happens, your LN2 dry shipper doesn’t become a liability. We’ve engineered it with buffer than you’ll probably ever need because “probably” isn’t good enough when you’re shipping a patient’s last viable embryos.

No Free Liquid Nitrogen No Airline Restrictions

CryoStork qualifies as a non-spillable cryogenic dry shipper and travels as not restricted under IATA Special Provision A152. That means it can go where conventional LN2 tanks and dewars can’t on passenger aircraft, across borders, through standard courier networks. Your samples move. The regulations don’t stop them.

Designed for Clinicians and Researchers, Not Just Lab Technicians

Most dry shippers are designed for the person who loads them. The CryoStork is designed for the full chain from the clinical embryologist packing it at 11pm before a next-morning transfer, to the courier who’s never seen cryogenic equipment in their life, to the receiving lab that needs to verify temperature integrity instantly. Every aspect of the design reflects real-world use, not ideal conditions.

Dry Shipper Price That Reflects Value, Not Just Cost

We get asked about dry shipper price a lot. And yes, you can find cheaper dry shippers online. You can also find cheaper parachutes. The question isn’t what a dry shipper costs to buy it’s what it costs when it fails. The CryoStork is priced for the professional market, not the hobbyist market. And if you’re comparing it against a generic liquid nitrogen dry shipper with no UK support, no traceability, and no accountability when something goes wrong, you’re not comparing like for like.

Science Behind the CryoStork Dry Shipper Dewar

CryoStork uses a high-density absorbent matrix inside a double-walled vacuum-insulated vessel the same basic principle as a cryogenic dewar but engineered specifically for transport rather than static storage.

Here’s how it works:

1. Charge the unit fill the CryoStork with liquid nitrogen and allow the sorbent core to absorb it fully (charging time varies by model)
2. Drain the free liquid once charged, tip out the free LN2. What remains is nitrogen held within the sorbent cold, stable, and travel-safe
3. Load your samples cannisters, goblets, straws, vials all sit in the vapour phase at cryogenic temperature
4. Ship no spill, no airline restriction, full temperature protection for the stated hold time

The vapour phase environment is actually critical for many biological samples. Direct contact with free liquid nitrogen can cause mechanical damage to certain cell types. CryoStork’s vapour-phase storage isn’t just a transport convenience it’s better biology.

Who Uses the CryoStork?

• IVF and fertility clinics transporting embryos, oocytes, and sperm between partner clinics and patients
• Biobanks and cord blood banks moving samples between storage and processing facilities
• Academic and commercial research labs shipping biological specimens internationally
• Hospitals and transplant centres transporting stem cell and bone marrow products
• Veterinary reproductive specialists working with equine, bovine, and canine genetics

If you’re working with biological material that needs to stay frozen and stay that way the CryoStork is built for you.

Why Cryolab?

Cryolab isn’t a general lab supplies company that sells dry shippers as a line item. Cryogenic transport and storage is what we do. CryoStork has been developed with direct input from fertility clinics, biobanks, and research institutions across the UK and Europe. We understand how samples travel, where the failure points are, and how to engineer around them.

We also offer:

• UK-based technical support talk to someone who knows cryogenics
• Regulatory guidance IATA, UKAS, HFEA we know the frameworks you’re operating in
• Custom configurations different canister sizes, accessories, and labelling options for clinical vs research use
