U.S. Solid 15 L Cryogenic Container Liquid Nitrogen (LN2) Dewar Semen Tank 6 Canisters Carry Bag

I'm a heavy equipment mobile mechanic. I bought this so I can go to my welding supply store and get liquid nitrogen to freeze and shrink bearings and pins. I purchased this in April of 2022. It has held up to field abuse and riding around in the back of the service truck. This summer, just as a test; I filled the tank up and then let it sit outside in the sun for about a month. Over a 4 week period, it lost 1/2 of the contents.........sitting in the baking sun......I'd say that's pretty good. It comes with stainless steel sample holders...........some of them are solid on the bottom, others have sieves to drain the liquid nitrogen out when removing the sample holders. These are color coded on top of the handle (I didn't need those so I threw them away). Also have a blue nylon sleeve covering the outside of the tank. The sleeve has some thin foam on the inside for protection of the tank and some insulating value. The sleeve has 2 straps (maybe like a packpack??) and a large pocket so you can store notes or any written info or records on the tank. Seems like a nice unit..........does what I need.............transporting liquid nitrogen.

It has only been a couple weeks since I filled the tank but with how much is left I get the feeling this is a great dewar. Edit: I filled it on November 21st and there is still some LN2 in there on January 9th!

buen tamaño, me gutaria que las cucharas vinieran dentro para protejertlas de cualquier deformación

This container works great! It keeps my nitrogen for 3 or more weeks if I dont open it too much.

Received fast, other than that the opening is so small it’s hard to pull up a canister. We even took out a canister to make it easier and it’s still a pain. We store ours in a controlled environment, up off the floor and we have to refill it every 8 weeks! Not sure if our is defective or what but I’d do your research before purchasing.

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.

I vacillated and vacillated and finally bought this. Was not sure that 3L dewar for $144 was going to be a decent value. 3L of LN cost about $20. It has now kept the liquid nitrogen in a liquid state for eight days, even after we used portions of it. We only removed the plug briefly in order to transfer LN to another container. Yhe plug is a plastic cap with a long "styrofoam" insert. The dewar was kept in a cool environment. it is my assumption that if you live in a hot climate, and you keep it in a warm atmosphere, that the liquid nitrogen will evaporate faster. I am very happy with this purchase. Very good value. It is not meant for long term storage.

I was tired of my local grocery stores constantly being out of dry ice so I upgraded to liquid nitrogen. I install bronze valve guides into cylinder heads as a performance upgrade for higher horsepower engines. Chilling the valve guides helps them slip right into the cylinder heads. It’s been almost a week since I filled the dewar and completed this batch of cylinder heads and there is still about 1.5 liters left in the dewar. It’s been sitting by the door in my shop exposed to the summer sun and it still hasn’t completely evaporated yet. Definitely follow the instructions to fill it completely for the first use.

La calidad superó mucho las expectativas. Lo utilizamos en el laboratorio para preservar embriones de peces para proyectos de secuenciación de nueva generación. Excelente compra n.n

It works perfect for doing cryo on my knife blades.

tank loose al nitrogen in 30 days

El equipo llegó en buenas condiciones, totalmente sellado y bien protegido. Llene hace 1 mes el tanque y aún hay Nitrogeno, lo conserva bien!

En al banco de semen me dijeron que era chino. Llenado al full solo dura máximo 3 semanas (sin destaparlo ni moverlo) agotandose la totalidad del líquido. Considero que contiene una publicidad engañosa.
