Anaerostat

Anaerostat (from anaerobes and Greek states - standing, installed) is a lighter-than-air aircraft, the lifting force of which is based on the Archimedean force acting on a shell filled with lighter-than-air gas.

The first anaerostats appeared at the end of the 18th century. They used heated air or hydrogen as the lifting gas. Modern anaerostats are most often filled with helium, less often with hydrogen.

Anaerostats are used for scientific observations, advertising, and tourism. There are free and tethered balloons.

The most common free balloons are hot air balloons. Tethered balloons are used to observe the Earth's surface from above. The largest anaerostats reach a volume of 200,000 m3.

Anaerostats are special devices that are used to maintain an anaerobic (without oxygen) environment in a laboratory or production facility. Anaerostats are necessary for various biological and medical research, as well as for the production of drugs and food products that require anaerobic conditions.

Anaerostats are sealed chambers that maintain a low level of oxygen inside (less than 2%). Inside the chambers there are special materials such as glass, ceramics or plastic that do not allow oxygen to pass through. Depending on the size of the chamber, anaerostats can be either small portable devices or large stationary systems.

One of the main advantages of anaerostats is that they allow research to be carried out in conditions as close as possible to natural ones. This allows scientists to more accurately study the processes occurring in organisms and create more effective medicines and food products. In addition, anaerostats ensure safety for laboratory workers and prevent the spread of dangerous bacteria and viruses.

However, anaerostats also have some disadvantages. For example, they can take up a lot of space and require special equipment to install and maintain. Also, when working with anaerostats, it is necessary to follow certain safety rules in order to avoid possible health problems for workers.

Overall, anaerostats are an important tool for research and production that allows for the creation of more effective and safer products.
