Each table has a low-voltage power supply, gas stove connection and tap
whichthat provide security in our laboratory. Extra security measures are taken by supplying all tables with water, electricity and gas in one place.For example, in heat experiments a teacher must open three keys and a student two keys in order for students canto burn thegas on their tables.
