Our Сhemical Laboratory Подготовили студентки группы ПНГ-21Д Аманова Милена, Киселева Елизавета и Бердникова Евгения.
Our chemical laboratory is not very big, but with good equipment. There are plakats and diogramms on the class walls.
There is a good equipment in laboratory: benches, a drying board, the muffle stove, Bunsen`s burner, extracting board, balance, electric stove, electric heating, etc.
These are various chemical bottles: measured flasks and glasses, pipettes, burettes, funnels, various flasks, test-tubes and tubes.
The laboratory equipment and bottles are made from chemically and thermally resistant materials, like glass, porcelain, platinum, lead, plasten.
Safety Rules in Chemical Laboratory
During the work in laboratory it is necessary to observe safety rules: don`t smoke.

It is necessary to work in laboratory in protective goggles, gloves and in uniform.
Each laboratory must have Mendeleyev`s table of chemical elements, a sink with two taps for cold and not water and the medicine chest, which contains iodine, cotton wool, bandage, heart means, liquid ammonia.
For the experimentation different chemical devices are used. For example, burettes, funnels, pipettes and measuring cylinders are used for titration, exsicator is used for substances keeping, cooling and carrying.
