The Tishchenko flask for washing gases through bulk substances produced by the Primelab company is a laboratory container. It has a closed shape with oppositely located branches, at the ends of which there are small olives. Thanks to their presence, the bottle can be reliably and firmly connected to the equipment using a soft hose. There is a partition in the middle that does not reach the end. Flushing of gases is carried out when they pass through granular substances, where unwanted impurities are retained. The Tishchenko bottle is made from high-quality borosilicate glass. It has absolute transparency, which allows you to observe all processes inside the container.
