CryoStork Dry Shipper: Complete Guide to Pricing, Models & Cryogenic Transport
When it comes to the safe transport of biological samples at cryogenic temperatures, not all dry shippers are equal. Whether you are shipping embryos between fertility clinics, moving cell lines between research institutions, or transporting valuable biobank material across the country or overseas, you need a dry shipper you can trust absolutely.
CryoStork® Series of Dry Shippers has been designed from the ground up for exactly this purpose delivering safe, secure, and efficient transportation of biological samples in the liquid nitrogen (LN₂) vapour phase. Available in a range of sizes from 2 litres up to the V10, there is a CryoStork dry shipper for every application and budget.
This guide covers everything you need to know: how dry shippers work, what the CryoStork range offers, dry shipper price expectations, and how to choose the right model for your needs.
What Is a Dry Shipper and Why Does It Matter?
A dry shipper is a specialist cryogenic container designed to keep biological samples at ultra-low temperatures typically between -150°C and -190°C — during transport, without the use of free liquid nitrogen. Instead of carrying liquid nitrogen openly, a dry shipper uses an internal absorbent material that soaks up the liquid nitrogen during charging. During transit, only nitrogen vapour is present, meaning there is no risk of liquid spillage.
This distinction is critically important. Free liquid nitrogen is classified as a hazardous material for freight purposes. A properly charged dry shipper, by contrast, contains no free liquid and is compliant with IATA regulations for air freight making it suitable for both domestic courier shipments and international biological transport.
CryoStork® dry shipper range takes this principle and elevates it, combining robust engineering, optimised absorbent capacity, and a compact design that makes handling and loading straightforward even in busy clinical or laboratory environments.
CryoStork® Series has been purpose-built for professionals who cannot afford to compromise on sample safety. Every model in the range is designed to accommodate round canisters for vapour-phase storage — the recommended method for preserving biological samples including oocytes, embryos, sperm, and cell lines during transit.

CryoStork® as a Dry Shipper Dewar – Understanding the Technology
The CryoStork® series belongs to the category of equipment often referred to as a dry shipper dewar — a term that combines two concepts. A dewar (named after the Scottish scientist Sir James Dewar) is any double-walled, vacuum-insulated cryogenic vessel. A dry shipper dewar specifically refers to a transport-ready dewar with an absorbent inner lining that holds the nitrogen in a non-liquid state.
What sets the CryoStork® apart from generic dry shipper dewar products on the market is the quality of its vacuum insulation, the efficiency of its absorbent material, and the care taken in the design of the neck plug assembly — all of which directly affect the vessel’s hold time and overall performance.
The result is a dry shipper dewar that consistently maintains temperatures in the LN₂ vapour phase throughout transit, giving you confidence that your samples will arrive in exactly the condition they left.
How to Charge Your CryoStork® Dry Shipper with Liquid Nitrogen
Charging a dry shipper liquid nitrogen vessel correctly is essential to performance. Here is the recommended process for all CryoStork® models:
- Pre-cool slowly — begin adding liquid nitrogen gradually to avoid thermal shock to the vessel.
- Fill to capacity — continue adding liquid nitrogen until the absorbent material is fully saturated. This may take 30 minutes to several hours depending on the model.
- Drain the excess — carefully invert or tilt the vessel to remove any free liquid nitrogen. The CryoStork® dry shipper should contain no free liquid before sealing.
- Verify the temperature — use a cryogenic thermocouple or temperature probe to confirm that the interior has reached the target range (typically -150°C or below).
- Load samples — transfer your biological samples into the canister(s) inside the CryoStork®.
- Seal and ship promptly — fit the neck plug securely and dispatch within the recommended hold-time window.
Always ensure that the time between charging and expected sample arrival is well within the stated hold time for your CryoStork® model, with a comfortable margin for unexpected delays.
