New Launch: ET-6 Livestock Liquid Nitrogen Tank – Reliable ET-Series Dewar For Frozen Semen and Embryo Storage

For decades, the ET-series liquid nitrogen tanks have been the top pick among livestock artificial insemination technicians worldwide, famous for balanced capacity, ultra-long static hold time, and field-ready durability. Today, we proudly release our brand-new ET-6 model, engineered to match the trusted performance of classic ET dewars while bringing better cost efficiency for breeding farms, semen banks, and mobile AI teams.

If you’re tired of frequent LN2 refills, small straw storage capacity, or unprotected semen canisters in low-quality tanks, our ET-6 solves all core pain points for daily frozen semen preservation. This post breaks down its full technical specs, standout benefits, and ideal breeding applications.

1. Complete Technical Parameters of Our New ET-6 LN2 Tank

Built for routine semen storage and on-farm breeding use, every dimension is optimized for standard livestock semen straws:

• Total Liquid Nitrogen Capacity: 6.5 Liters

• Neck Opening Diameter: 55 mm

• Static Hold Time: Up to 43 full days (no refills under standard indoor conditions)

• Equipped Canisters: 6 pcs

• Single Canister Size: 43 mm diameter × 127 mm height

• Max Straw Storage Volume:

  900 doses of 0.5ml semen straws

  1,860 doses of 0.25ml semen straws

• Standard Accessories: Lockable safety lid + thick protective outer jacket

2. Core Advantages That Make ET-6 Stand Out In The ET Dewar Lineup

2.1 Extra-Long 43-Day Static Hold, Cut LN2 Refill Costs

Many 6L-class livestock dewars only offer 25–35 days of static storage. Our ET-6 adopts upgraded multi-layer vacuum insulation, delivering a stable 43-day holding cycle. Breeding farms and mobile AI crews reduce liquid nitrogen purchasing and refilling frequency drastically, lowering long-term operating expenses.

2.2 High-Density 6-Canister Layout, Massive Straw Storage

Comes with six independent 127mm tall canisters. Separated storage lets you categorize bull, boar, ram, or goat semen separately without cross-contamination. The huge capacity of 1,860 × 0.25ml straws or 900 × 0.5ml straws meets the storage demand of mid-scale breeding stations and private semen distributors.

2.3 55mm Wide Neck – Easy Fast Straw Access

The wide 55mm neck opening avoids narrow bottlenecks common on small dewars. Technicians can lift and swap canisters smoothly during daily insemination work, saving lots of labor time during peak breeding seasons.

2.4 Full Safety Package: Lockable Lid + Protective Outer Jacket

• Lockable lid: Prevent unauthorized opening, accidental LN2 spillage, and semen sample loss, perfect for shared farm labs and mobile transport.

• Thick padded outer jacket: Shock, scratch, and cold-resistance protection during truck transport, farm bumpy roads, or field visits. The jacket also blocks direct sunlight to slow the loss of vacuum.

2.5 Portable, Field-Oriented ET-Series Design

Following the classic ET-series lightweight aluminum structure, the ET-6 balances compact size and sufficient storage. It’s easy to carry between barns, breeding stations, and remote farm sites for on-demand artificial insemination services.

3. Who Is The ET-6 Liquid Nitrogen Tank For?

3.1 Small & Medium Livestock Breeding Farms

Suitable for cattle, pig, sheep, and goat farms with a medium semen inventory. The 43-day hold time avoids weekly LN2 refills for rural farms with limited access to gas supplies.

3.2 Mobile Artificial Insemination Technicians

Lightweight build + protective travel jacket makes ET-6 the ideal carry-on tank for technicians traveling between multiple client ranches every week.

3.3 Local Semen Distribution Labs

Large straw capacity stores multiple breeds’ elite genetic semen in one compact tank, convenient for regional semen sales and germplasm exchange.

3.4 Veterinary Reproduction Clinics

Matches our full breeding lab equipment lineup: programmable semen coolers, thermostatic thaw cups, and heated sperm microscopes to form a complete semen processing workflow.

5. Frequently Asked Questions About The ET-6 Semen Dewar

Q1: How does the ET-6 compare to mainstream classic ET tanks on the market?

A: It adopts the mature ET-series design concept specifically for livestock semen storage, matching the reliable performance customers trust, with longer static hold time and larger straw storage capacity at a competitive price point.

Q2: What’s the static hold time based on?

A: The 43-day static holding period is tested under standard indoor room temperature, without frequent opening of the tank lid. Frequent daily sampling will slightly shorten the storage cycle.

Q3: Can I transport this tank to different farms?

A: Absolutely. The matching thick outer shockproof jacket and lockable lid secure the tank during road transport, ideal for mobile AI service teams.

Q4: Are the 43×127mm canisters replaceable separately?

A: Yes, individual spare canisters are available as replacement parts for long-term use.

Q5: Does this tank work with your other breeding lab equipment?

A: Perfectly matched. Pair the ET-6 with our programmable semen cooling system, thermostatic thaw cup, and heated sperm observation microscope for a full one-stop semen cryopreservation lab setup.
