The Largest Aluminum Liquid Nitrogen Tank For Semen Straw Storage: Heyi Biotech XT 47

Short answer: The XT 47 is the largest aluminum liquid nitrogen tank available in the industry. It holds 47 liters of liquid nitrogen, stores up to 23,604 doses of 0.25 ml straws (or 10,704 doses of 0.5 ml straws), and delivers a 130-day static hold time — meaning most operations only need to top up liquid nitrogen about every two months. It is built for high-volume, long-term storage of frozen semen and many other biological samples.

Every frozen semen program eventually faces the same two questions: how many straws can I store, and how often do I have to refill? Small tanks answer the first question poorly and the second question badly. Large stainless steel biobanks answer both — but at a heavy price tag and a fixed installation footprint.

The XT 47 is designed for the space in between: the largest aluminum liquid nitrogen tank in the industry, with the low maintenance burden of a genuinely long hold time.

Why the XT 47 Is the Sweet Spot for High-Volume Semen Storage

Massive straw capacity in one compact aluminum tank

With 23,604 doses of 0.25 ml straws in a single 47-liter unit, the XT 47 holds what would normally require several smaller dewars. One tank, one location, one inventory — simpler storage management for AI centers, bull stations and breeding cooperatives with serious daily output.

A 130-day static hold time means refilling about every two months

The XT 47 delivers a static hold time of up to 130 days. Under normal operation, most users only need to top up liquid nitrogen about once every two months. No weekly topping-up rounds, no constant level checks, no interrupted workflow. For facilities where liquid nitrogen supply is expensive or logistically difficult, this long interval is a major operational advantage.

Extremely low liquid nitrogen consumption per straw

What matters for long-term economics is not just tank size — it is the liquid nitrogen consumed per straw stored. The XT 47 combines high-density straw capacity with efficient insulation, so the amount of liquid nitrogen needed to keep each dose safe is very small. Lower per-dose consumption directly cuts your cryogen budget over months and years of storage.

Aluminum construction, easy to position

Unlike heavy stainless steel biobanks, the XT 47 is an aluminum liquid nitrogen tank — lighter, easier to move, and simpler to install in an existing semen processing room, mobile lab, or breeding station. You get industry-leading straw capacity without biobank-level installation requirements.

Beyond Semen Straws: A Versatile Biological Sample Storage Tank

The XT 47 is not limited to frozen semen. Its 127 mm neck opening, 6 or 10 canisters, and stable long-term hold time make it a genuinely versatile storage vessel for biological samples that need ultra-low temperature preservation:

• Embryos — for embryo transfer programs and genetic banking

• Stem cells — for research institutes and cell therapy facilities

• Seeds — for plant genetic resource conservation

• Skin tissue — for tissue banks and clinical sample storage

• Cord blood — for cord blood banking operations

• Vaccines — for long-term refrigerated and cryogenic vaccine storage

Wherever a large volume of biological material must be preserved for years at -196°C with minimal attention, the XT 47 fits.

Choosing the Right Canister Configuration

The XT 47 offers two canister options, so you can match the layout to your sample type:

Configuration	Canister Diameter	Best For
6 canisters	104 mm	Bulk 0.25 ml / 0.5 ml semen straws, high-volume storage
10 canisters	72 mm	Mixed samples, smaller racks, embryo and tissue storage

Choose 6 large canisters for maximum straw density, or 10 smaller canisters for more organized separation of different batches, sires, or sample types.

FAQ

How many straws can the XT 47 store?

Up to 23,604 doses of 0.25 ml straws, or 10,704 doses of 0.5 ml straws.

How often do I need to refill liquid nitrogen?

With a static hold time of 130 days, most operations only need to top up about once every two months under normal use.

Is the XT 47 only for semen straws?

No. It is also suitable for embryos, stem cells, seeds, skin tissue, cord blood, and vaccines — any biological sample requiring long-term ultra-low temperature storage.

Which canister configuration should I choose?

Choose 6 canisters (104 mm) for maximum straw capacity, or 10 canisters (72 mm) for better batch separation and mixed sample types.

Why is per-straw liquid nitrogen consumption important?

Lower liquid nitrogen consumption per straw means your cryogen costs stay low over years of storage. The XT 47 pairs high-density straw capacity with efficient insulation for minimal per-dose operating cost.

Conclusion: One Tank for Volume, Longevity and Versatility

For high-volume, long-term storage of frozen semen, the XT 47 delivers what matters most: the largest aluminum liquid nitrogen tank in the industry, a 130-day static hold time that cuts refilling to about once every two months, and remarkably low liquid nitrogen consumption per straw stored.

And when your needs go beyond semen — embryos, stem cells, seeds, tissue, cord blood, vaccines — the same tank keeps them safe at -196°C for years.
