Dewar Tank: A Complete Guide for Beginners.
If you are new to the world of scientific research, it's essential to know about dewar tanks. Dewar tanks are vital in the storage and transportation of cryogenic fluids like liquid nitrogen. In this article, we will discuss ten essential questions about dewar tanks.
1. What is a dewar tank?
A dewar tank is a container that can store and transport cryogenic liquids like liquid nitrogen. It consists of a double-walled stainless steel vessel that is vacuum insulated. It can sustain low temperatures without causing damage to the liquid inside.
2. What are the types of dewar tanks?
There are three types of dewar tanks - open-mouth dewars, pressurized dewars, and cryogenic liquid cylinders. Open-mouth dewars are commonly used for short-term storage, while pressurized dewars are used for longer storage times and transportation. Cryogenic liquid cylinders are used for high-volume storage and transportation.
3. What are the sizes of dewar tanks?
Dewar tanks come in different sizes, ranging from small handheld sizes to large truck-mounted sizes.
4. How long can a dewar tank keep liquid nitrogen?
The length of time that a dewar tank can store liquid nitrogen depends on various factors like the size of the tank, the type of dewar tank, and the level of vacuum insulation. For example, a pressurized dewar tank can store liquid nitrogen for a more extended period than an open-mouth dewar tank.
5. How do you refill a dewar tank?
To refill a dewar tank, you should contact a supplier specialized in providing cryogenic liquid gas. They can deliver the gas and refill the tank at your laboratory or research facility.
6. How do you handle and operate a dewar tank?
It's essential to follow the manufacturer's instructions when handling and operating a dewar tank. Wear appropriate protective gear and avoid excessive tilting or shaking.
7. How do you transport a dewar tank?
Transporting a dewar tank should be done carefully, as it contains liquid nitrogen, which can be hazardous. Dewar tanks should be secured and kept upright in a van or truck during transportation.
8. What is the cost of a dewar tank?
The cost of a dewar tank depends on the size and type of the tank. However, they are generally affordable and can last for many years if well-maintained.
9. How does vacuum insulation work in a dewar tank?
The vacuum insulation in a dewar tank helps to prevent heat transfer between the inner and outer walls of the tank. This, in turn, helps to maintain low temperatures for the liquid nitrogen inside.
10. What are the safety precautions to take when handling a dewar tank?
Safety precautions when handling a dewar tank include wearing proper protective gear, carefully handling and transporting the tank, and avoiding contact with skin or eyes when handling liquid nitrogen.
In conclusion, for any scientific research that requires cryogenic liquids, dewar tanks are essential. Knowing the basics of handling, operating, transporting, and maintaining dewar tanks is crucial.
