Liquid Helium Dewar

A liquid helium dewar is a special container designed to store liquid helium at extremely low temperatures, below helium's boiling point of about 4.2 Kelvin (-268.93 degrees Celsius). These dewars are made of highly thermally insulating materials such as stainless steel or other materials capable of maintaining the low temperatures necessary to keep the helium in liquid form.

Liquid helium dewars are very important in various applications, especially in the fields of physics research, medicine, and technology.

Some examples of its uses include:

Physics Research

Dewars are used in physics experiments that require very low temperatures, such as research on superconductivity, strong magnetism, and other quantum phenomena.

Medical Cryogenics

Helium is used in the medical field for MRI (Magnetic Resonance Imaging) because of its ability to create the magnetic field necessary for accurate body images. Dewars are used to store the helium used in MRI machines.

Space Research

Dewar is used in the development and testing of components used in ultra-low temperature environments in space, such as cryogenic sensors and cooling systems on satellites.

Biological Sample Maintenance

In biology, helium is used to freeze and store temperature-sensitive biological samples, such as stem cells or genetic samples.

Chemical and Materials Research

Dewars are also used in chemistry and materials research to study the behavior of substances at low temperatures, study phase changes, and develop new materials.

The use of liquid helium in this dewar allows experiments and technological applications that require very low temperatures to be carried out efficiently and accurately.
