TAP

HOW TO USE IT?

They are directly connected to a bottle filled with the solution and allow precise dispensing of volumes.

The tap is located at the top. Gas is collected by displacing fluid from the burette, and the volume of gas is measured by the volume of fluid displaced.

Thanks to the coloring of the glass, it guarantees protection from light and helps preserve the quality of the solution.
