Written by:



Time to read 2 min

Are you looking for a long-term storage dewar for semen, embryos or eggs? And do you need a portable, lightweight tank able to store large numbers of straws? If so, the Standard Capacity (SC) and Extra Capacity (XC) series of aluminum dewars could be just what you need.

The SC series offers standard straw capacity with longer hold times, depending on the size of the dewar. Meanwhile, the Semen Tank - XC series offers large straw capacities, along with different canister options depending on your inventory management.

Whichever you choose, you can rely on both of these durable units to perform. They’ll provide quality storage for your elite genetics for many years to come, even in the most demanding environments. What’s more, both the SC and XC models offer low liquid nitrogen consumption. This is in addition to some innovative design features that offer extra security for your samples.

Bend Don't Break™ (Patent Pending)

This redesigned top head can absorb G-force damage to the neck area of the dewar. This minimizes the chance of product loss through mishandling and during transportation.

Storage Tanks

The TWO primary considerations in choosing an MVE semen/embryo storage tank are

- Number of units you will be storing
- Number of weeks a tank holds (In other words, time between the refills)

MVE  Storage tanks are divided into two categories, SC (Standard Capacity) and XC (X-tra capacity). The handy dandy chart below illustrates the various models and capacities of our most popular models.
