Each table has a low-voltage power supply, gas stove connection and tap which provide security in our laboratory. Extra security measures are taken by supplying all tables with water, electric and gas in one place.For example, in heat experiments a teacher must open three keys and a student two keys in order students can burn the gas on their tables. Likewise, a student can’t use the electricity unless a teacher allows from the control panel.
