Jars and gas collectors are both commonly used chemical experimental instruments, but there are some differences in structure and use between the two.
Specifics:
1.Structure
Jar: The bottle mouth of the jar is larger, the diameter is generally 50-100mm, and the inner wall of the bottle mouth is not frosted, which is used to hold solid reagents.
Gas collection cylinder: The mouth of the gas collection cylinder is small, the diameter is generally 10-30mm, and the inner wall of the bottle mouth is frosted for gas collection.
2.Uses:
Jars: Jars are mainly used to hold solid reagents, such as metals, salts, acids and alkalis. In experiments, jars can also be used for soaking, filtration, evaporation, and other operations.
Gas Collector Cylinder: Gas Collector Cylinder is mainly used to collect gases, such as oxygen, hydrogen, carbon dioxide, etc. In experiments, gas collection cylinders can also be used for reaction vessels, drying vessels, etc.
3.Precautions
When using the jar, attention should be paid to the tightness of the stopper to prevent the leakage of the reagent.
When using the gas collection cylinder, attention should be paid to the cleanliness of the bottle mouth to prevent gas leakage or pollution.
Summary:
Jars and gas collectors are commonly used chemical laboratory instruments and play an important role in experiments. When using them, you should pay attention to the structure and use of both, and follow the relevant precautions.
