Common equipment in chemical laboratories

Common equipment in chemical laboratories are as follows:
1. Iron stand: used to fix and support various instruments, generally used for filtration, heating and other experimental operations.
2, beaker: 1 dissolved solid matter, preparation of the solution, and the dilution and concentration of the solution 2 can also be used to make a larger amount of reaction between substances
3. Measuring cylinder: measuring liquid volume
4. Gas cylinder: used to collect or store a small amount of gas, and can also be used as a reaction vessel for partial reaction.
5, test tube: 1 small amount of reagent reaction vessel 2 can also be used to collect a small amount of gas container 3 or for the device into a small gas generator
6, test tube holder: used to hold the test tube
7, glass rod: used to stir, filter or transfer liquid
8, alcohol lamp: for heating
9, plastic dropper: plastic dropper for suction and drop a small amount of liquid
10, drop bottle: drop bottle for liquid medicine
11, jar: (the inner wall is sanded) is often used to hold solid reagents, can also be used as gas cylinders
12, fine mouth bottle: glassware for storing liquid reagents
13. Flask: There is a round bottom flask. The flat bottom flask 1 is usually used to make a large amount of liquid reaction. 2 It can also be used as a device gas generator.
14. Conical flask: 1 heating liquid, 2 can also be used for device gas generator and bottle washer 3 can also be used for drip container in titration.
15. Evaporating dish: usually used for concentration or evaporation of the solution.

16. Funnel: used to add liquid to test tubes, alcohol lamps, etc. Common funnel, separatory funnel (can control flow rate) and long neck funnel
