YDS series liquid nitrogen tanks are mainly used to store liquid nitrogen and biological samples.

Liquid nitrogen tank, also known as "liquid nitrogen biological container", is a low-temperature container that can store liquid nitrogen and biological samples. According to their uses, they can be divided into liquid nitrogen storage tanks, self-pressurized liquid nitrogen tanks, and gas-phase liquid nitrogen tanks. Among them, liquid nitrogen storage tanks can also be subdivided into storage types and transportation types. The storage type is mainly used for static storage and is not suitable for long-distance transportation during work; the transportation type is specially designed to meet transportation conditions and has an internal shock-proof function. Support, while also allowing for static storage when needed.

Since liquid nitrogen tanks are used to store samples, they need to be used correctly:

before use:

1. Check the jar

Check whether the shell has any dents or dents, and whether the vacuum port is intact;

Check whether there are foreign objects or impurities in the tank. If there are foreign objects, they need to be removed to prevent the inner tank from being corroded;

2. Pre-cooling

Inject a small amount of liquid nitrogen into the tank to cool the inner tank;

After injecting liquid nitrogen, cover the neck plug and wait for a few hours until the boiling phenomenon disappears and the liquid nitrogen becomes stable;

Pre-cooling is complete when the water droplets or frost produced by heat exchange on the can body have disappeared and there is no white frost on the neck plug.

when using it:

1.Storage

Store in a well-ventilated and cool place, do not expose to direct sunlight;

Keep upright and do not tilt, lay horizontally, invert, pile up, hit each other or collide with other objects;

2.Transportation

Handle it gently when moving and avoid sudden movements;

It must be fixed during transportation to ensure that it will not shake during transportation;

After use:

Cleaning:

1. After the liquid nitrogen has evaporated, let it sit for several hours until the internal temperature of the container returns to normal temperature.

2. Pour warm water at 40℃-50℃ into the container, and then wipe it with a cloth.

3. Rinse 2-3 times with clean water.

4. Invert the container to dry naturally. You can also use hot air to dry it. The suitable temperature is 40℃-50℃. Avoid hot air above 60℃.

After cleaning, store it in a dry and ventilated place, and check it regularly for next use.
