1, used as a reactor for substances.

2. Dissolve and crystallize a substance.

3. Extract, evaporate, concentrate or heat the solution.

4. Weigh the corrosive solid drugs.

Type of beaker:

1, low beaker. The low-profile beaker is the most commonly used beaker in the laboratory. It was designed by British chemist John Joseph Griffin, so it is also called the low-profile Griffin beaker. The height of the short beaker is about 1.4 times its diameter, which is used in most chemical experiments.

Beakers with different specifications will have different uses, and beakers with a volume of 1 to 50mL are mainly used for micro-analysis. Beakers with a capacity of 50 to 2000 ml are mainly used for continuous analysis, as containers for general chemical reactions, or for temporary storage of liquids.

2. Tall beaker. The height of tall beakers (also called Berg beakers or electrolytic beakers) is about twice the diameter.

Its unique thin and high shape can prevent it from splashing or dripping liquid from above when heated, and it can also be used to replace electrolyzer for electrolysis and occasionally replace conical flask for titration. Because the high-type beaker is smaller than the low-type beaker with the same height, the dosage of reagents can be relatively reduced when used in experiments, and the effect of saving reagents can be achieved.

3. conical beaker. The conical beaker (also known as Freund's beaker, milk beaker or triangular beaker) is similar to the conical bottle in shape, with a wide bottom and a narrow top, which is convenient for oscillation and prevents liquid from overflowing. It can be used to receive fractions in the process of atmospheric distillation and contain the liquid to be measured in the process of titration.

4. Dye the beaker. Dye beaker has a cone shape with a wide top and a narrow bottom, but it suddenly widens in the middle and upper part, which is used in dyeing related experiments.
