The laboratory has its own equipment. It is equipped with special
laboratory tables besides the demonstration table which stands between the two rows of tables and in front of them. In our experiments we use laboratory vessels and glassware of different kinds. There are three groups of them in the laboratory: glassware for general use, glassware for special use and glassware for measuring. Students carry out experiments using test-tubes, funnels, flasks, retorts, burettes, graduated cylinders, measuring glasses and pipettes. They also have microscopes, analytical balances, distillators, burners to heat solutions and thermometers at hand. The most widely available reagents at our laboratory are acids, alkalis,
