LPT Series Low-Pressure Liquid Nitrogen Tank – All-In-One Storage, Transport & LN2 Dispensing Solution

If your lab, livestock breeding station, or industrial workshop frequently refills small semen/embryo dewars, you must have struggled with messy manual LN2 pouring, unstable high-pressure tanks, or frequent gas supplier deliveries. Conventional high-pressure LN2 vessels carry safety risks and complex operation, while small portable dewars can’t meet centralized liquid nitrogen supply demands.

Our exclusive LPT series low-pressure liquid nitrogen tank solves all these pain points perfectly. Designed with working pressure below 1 bar, covering a full capacity range from 5L to 2000L, it integrates three core functions: liquid nitrogen storage, short-distance transfer, and automatic LN2 dispensing to all types of small cryogenic containers.

This guide covers core product advantages, standardized operation workflow, industry application scenarios, and comparison with ordinary cryogenic tanks to help you pick the right LPT model for your facility.

8 Unmatched Advantages of LPT Low-Pressure Liquid Nitrogen Tank

1. Ultra-Safe Working Pressure (＜1 Bar)

Compared with high-pressure cryogenic tanks (3–8 bar or even higher), the LPT series operates at pressures below 1 bar. No dangerous high-pressure accumulation during vaporization, greatly reducing explosion & leakage risks for daily lab and farm operation, fully compliant with global cryogenic safety standards.

2. Three-In-One Integrated Function (Store + Transport + Dispense)

No separate storage tank + transfer cart + filling device required. One single LPT tank completes:

• Long-term liquid nitrogen storage

• Short-distance on-site transport between workshops/barns

• Automatic LN2 refilling to small semen dewars, embryo dry shippers, and lab cryo containers

  Greatly reduce the investment in extra equipment and save lab floor space.

3. Full Capacity Range 5L–2000L For All Scales

Mini 5–50L portable models for small breeding labs & university research rooms; medium 100–500L for mid-size AI stations; large 1000/2000L stationary tanks for gas distributors & large-scale embryo transfer centers. One product line covers all customer demands.

4. Automatic Self-Pressurization For Effortless LN2 Dispensing

Built-in pressure boosting system generates tiny internal pressure by slight natural vaporization, pushing liquid nitrogen out steadily without external pumps. Operators can refill multiple small dewars continuously with one-touch valve control, no manual pouring.

5. Ultra-Low Evaporation Loss, Cut LN2 Procurement Cost

Adopts advanced multi-layer vacuum super insulation + perlite interlayer filling. Minimal heat ingress slows LN2 boil-off drastically, extending refill cycles and lowering your monthly liquid nitrogen purchasing expense.

6. Simple, Low-Maintenance Valve Assembly

Standardized color-coded valve group with pressure & liquid level real-time display. No complicated mechanical parts. Wear-resistant universal spare parts, no expensive proprietary accessories required for long-term upkeep.

7. Flexible Mobility Design

Small & medium LPT tanks install heavy-duty brake casters, easy to push between processing rooms, semen collection yards, and embryo labs. Large 1000/2000L versions adopt a stable fixed foundation base for permanent central supply stations.

8. Wide Compatibility With All Cryogenic Containers

Liquid outlet matches standard cryogenic transfer hoses, perfectly refills all brands of livestock semen tanks, embryo dry shippers, mini LN2 dewars, and lab cryo vessels, fully compatible with your existing breeding lab equipment lineup.

Standard Operation Workflow – Store, Transfer & Dispense LN2 With LPT Tank

• Storage Stage: Deliver bulk liquid nitrogen into the LPT tank via tanker, close all valves for sealed low-temperature storage, and monitor liquid level & pressure regularly.

• Short-Distance Transfer: Lock brake casters on small/medium models, push the tank to the target processing area safely.

• LN2 Dispensing Stage

  1. Connect the cryo transfer hose between the LPT liquid outlet and the target small dewar filling port

  2. Slightly open the self-pressurization valve to build internal pressure under 1 bar

  3. Turn on the liquid outlet valve, and stable LN2 flows into the target container automatically

  4. Close the liquid valve once full, shut the pressurization valve, and disconnect the hose

• Finish operation, vent excess internal gas if pressure rises slightly, keep tank sealed for storage.

Frequently Asked Questions About LPT Low-Pressure LN2 Tank

Q1: Is a pressure below 1 bar safe for daily lab operation?

A: Absolutely. The LPT series only generates tiny internal pressure from natural LN2 vaporization, equipped with a safety relief vent valve to discharge excess gas automatically. No high-pressure buildup risk, far safer than standard pressurized microbulk tanks.

Q2: Can I use the LPT tank to refill all brands of semen dewars?

A: Yes, standard liquid outlet port supports universal cryogenic transfer hoses, compatible with all livestock LN2 storage tanks and embryo dry shippers on the market.

Q3: What size LPT tank should I choose for a mid-size breeding farm?

A: Farms processing under 5000 straws monthly pick 100–500L wheeled LPT models; large embryo transfer stations or gas suppliers select 1000L/2000L stationary versions.

Q4: Does the tank need an external pump to dispense liquid nitrogen?

A: No built-in or external pump required. The self-pressurization system uses natural LN2 evaporation to create gentle internal pressure for stable liquid outflow, simple and failure-free.

Q5: What supporting breeding equipment matches the LPT tank?

A: Perfectly matched with our full lab lineup: programmable semen coolers, embryo freezing machines, thermostatic thaw cups, heated sperm microscopes, and portable straw printers.
