Liquid Level Apparatus, Boro Glass, on a Stand

Liquid Level Apparatus, known also as Equilibrium Tube Apparatus or Communicating Tubes. Traditional school teaching aid, still the best to demonstrate students that liquid will stand at the same level no matter how differently the vessels are shaped.
The Apparatus is made of high quality, borosilicate glass, and consists of four differently shaped glass tubes that are linked at the bottom by a horizontal glass tube, and open at the top. The whole apparatus is mounted on the base.
Due to the stand, after filling the apparatus, you can also tilt it toward one side and check again the level of the liquid.
We recommend to use coloured water (with colouring dye, cooking or other) for better demonstration.
