MVE XC 20 Signature Semen Tank – Your Gateway to Champion Genetics

Elevate your breeding program with the XC 20 Signature, the world’s best-selling cryogenic semen tank and the trusted choice of serious breeders who demand nothing less than champion results. Designed specifically for the demands of modern artificial insemination (AI), this powerhouse tank lets you safely store and protect the genetics of elite sires—so you can produce superior offspring without the cost, risk, or logistics of live-animal transport.

With a massive 660 straw capacity (1/2 cc) and an impressive 142-day (20-week) working hold time, the XC 20 Signature gives you unmatched flexibility. Whether you’re syncing a single elite flush or building an entire AI program for cattle, goats, or other livestock, your valuable semen stays viable and ready at a moment’s notice. Its ultra-low evaporation rate of just 0.09 L/day and 20.5 L nitrogen capacity mean fewer refills, lower operating costs, and complete peace of mind.

What truly sets the Signature series apart is its exclusive Bend Don’t Break™ and Semen Safe™ durability features. The reinforced composite neck is 20% stronger, engineered to withstand the bumps, drops, and daily handling that come with real-world breeding operations—preventing costly semen loss and protecting your investment in champion bloodlines.

Lightweight yet rugged (just 26 lbs empty), easy to transport, and backed by a 5-year vacuum warranty plus a 2-year parts warranty, the XC 20 Signature is the perfect starter or backup tank for new breeders and established operations alike. Color-coded canisters and a simple lid system make inventory a breeze, so you spend less time managing tanks and more time producing winners.

When you choose the XC 20 Signature, you’re not just buying a tank—you’re investing in the future of your herd. Artificial insemination has revolutionized the breeding of champions, and this is the tank that makes it reliable, affordable, and stress-free.

Secure your genetics. Breed the champions of tomorrow.

    Customer photo review of MVE XC 20 Signature _ BEST SELLING TANK IN THE WORLD _ 660 Straws, HOLDS 20 weeks _ Five (5) Year Vacuum Warranty

    Prior to purchasing, sementanks.com was so helpful in helping me choose which tank fit my needs. After purchasing, the tank arrived with a damaged lid that occurred during shipping. I contacted sementanks.com and within minutes they were asking for the tanks serial number and shipped replacement parts immediately! You can't beat their customer service!! I've not filled or started using the tank yet, but I'm sure it's great!
