In laboratories conducting various analyzes with chemical mixtures, it is necessary to accurately measure the amount of bulk or liquid substance. For these works, special dishes with a measuring scale are required. Such devices include pipettes, beakers, burettes, flasks. In this article we will consider in detail what a beaker and its varieties are.
Product Description
Measuring utensils are used by various medical, industrial, educational institutions, as well as research institutes and catering kitchens. What is a beaker? This is a tall glass made of plastic or glass, which is used to measure the volume of chemical solutions and reagents in a liquid state. The beaker has the shape of a cylinder or cone with existing divisions on the outside that measure milliliters. The numerical scale starts from the bottom of the device and increases to its top. The container may have a bottom or a separate base, which during operation is attached to the bottom of the dishes for stability. For ease of pouring solutions, the glass at the neck has a special spout and a side handle.
How is measuring capacitance used?
We learned what a beaker is, then we will consider how it is used in laboratories.
- Turbid liquids often settle in glasses until sedimentary substances are collected at the bottom of the dishes.
- Beakers are used in the manufacture of complex chemicals .
- With their help, volumes of liquids of different densities that cannot be mixed are measured.
- Complex drugs are also dosed.
Types of Beakers
Glasses are divided into classes that determine the accuracy of the device. Class “A” includes beakers with high measurement accuracy, and class “B” - with low. The error margin for dishes with different capacities is determined by GOST. But the maximum deviation should not be higher than one scale division.
Beakers differ in the material from which they are made. There are glasses made of porcelain, plastic, glass with various additives resistant to chemicals. Depending on the application, the dishes have a different volume, which varies from 10 ml to 2 liters.
From the article you learned about what a beaker is. It can be used at home. Measure the required amount of cereal, milk and other bulk and liquid products. Beakers can also be used during repairs in the apartment, measuring the volume of dry mixes.
