Transferring substances and liquids into other states of aggregation and thus initiating further reactions is very important for the daily work in the laboratory. A wide variety of vessels, apparatus and equipment are used for these work. Reaction controls, test series and preliminary samples are usually carried out in test tubes due to the small amounts of substance removed.
