The vacuum flask is a commonly used laboratory instrument, typically used to connect plastic tubing to a vacuum pump. The vacuum flask, also known as the Buchner flask, is one of the widely used laboratory containers. It is a type of glass flask made from borosilicate or pyrex glass, characterized by its high thickness. There is a tube on the neck of this container, which is usually used to connect plastic tubing to the vacuum pump.
Important features of this laboratory container include its body’s resistance to high pressure, or what is known as vacuum capability. High transparency is another characteristic of this container. This flask comes in various sizes and is usually graduated to allow for the storage of different volumes.
