Lelchitsky expirator

A Lelchitsky expirator is a device for blowing air bubbles out of a liquid. This device is widely used in chemistry and physics to demonstrate the process of breathing and exhalation of air. It is a tube, one end of which is under water, and the other end is connected to a rubber bulb. When you press the bulb, water begins to blow out of the tube, creating air bubbles.

The Lelchitsky expirator was invented in the 18th century by the Italian scientist Luigi Lelchitsky. He used this device to demonstrate the processes of breathing and exhalation that occur in the human lungs. In the 19th century, the device became popular among scientists and students, who used it to study the processes of respiration and gas exchange in the body.

Today, the Lelchitsky expirator continues to be used in scientific research and education. It allows you to clearly demonstrate the processes of breathing and exhalation of gases, which helps to better understand the physiology of humans and animals. In addition, the device can be used to study the properties of gases and liquids, as well as to demonstrate various physical processes.

Lelchitsky evaporators - belongs to the category of household chemicals and is widely used for processing fabrics, things, home textiles, as well as in public places (swimming pools, water parks) for disinfection and disinfection of water. Expirators are a fundamentally new method of sterilization that allows you to quickly and effectively destroy bacteria and fungi without using chemicals (chlorine, ammonia, formaldehyde, etc.) and does not harm others. This is due to the fact that during the sterilization process an ozone dispenser is used, which is a compact device made of a metal case with control elements and indication
