Antech CryoCarrier 4B — A dry shipper for transporting biological samples in cold nitrogen vapour. An absorbent retains LN₂; after preparation according to the instructions, no free liquid should remain in the working chamber.
CAPACITY6BBC-A bags
ABSORBED LN₂3.5 LManufacturer specification
STATIC HOLDOVER9 daysLaboratory figure
Key advantages
- Vapour-phase transport avoids immersing samples in free LN₂.
- The absorbent retains nitrogen after correct charging and removal of excess liquid.
- Select the model for the sample format, neck opening and route duration.
- Select an external case for compatibility with the specific container.
- A temperature logger can document transport conditions.
- Capacity depends on cassettes, canisters or racks, rather than tank volume alone.

Application and configuration
Charge and prepare the dry shipper according to its instructions. Static holdover values are measured under test conditions; practical duration depends on preparation, openings, load and route conditions. They are not a guaranteed delivery duration.
Gross tank volume and absorbed nitrogen volume are different parameters. A warm or new container requires extended preparation; a short recharge cycle should not be assumed for first use.
Specify sample holders, case, logger and documentation in the order. Agree packaging, route and carrier requirements; the name Dry Shipper alone does not establish acceptance of a particular shipment for air transport.
B-series capacity here is for BBC-A cassettes. Other bag and cassette formats may have different capacities; confirm the filled bag and cassette dimensions.
The photograph illustrates the series using CryoCarrier 25R; it is not an exact photograph of this model. The model and agreed specification define the order.
Is the stated holdover a guaranteed route duration?
No. A safety margin and temperature verification are required for the specific process.
Are the case and logger included?
Their inclusion must be confirmed in the order specification.
