My daughter became an ai technician and needed a tank to hold cow straws in. We took this tank to the local cattle genetics place, and they were nice enough to fill it up, but they recommended we have a tank with a longer canister tube for the semen straw holders. These are short, but if you cut the straw holders in half, they will fit the canisters well. You just can not hold as many straws, but that was ok for my daughter, who is only a local ai tech for small farms anyway. I suggest that US Solids will make their canisters taller, since it seems to be something that the semen straw people want or offer the option of taller canisters. Her tank was filled up recently, but she bought the measuring stick to watch it. I will do an update on how this tank performs. Thanks!
Update: This tanks does very well. We watched the cm's and it was consistantly losing 1 cm a week. then when it got to around 10 cm's it started jumping down by 2 to 3 cms. We refilled it at 7 cms. All the straws inside were still good! Nice little tank! I highly recommend if you are starting out and need to hold some straws for your own cows or as a small starter ai tech.
