Chemical laboratory rules

1. According to the principle of unification of theory and practice, pre-experience should be pre-experiment, and the purpose of the experiment and the experimental method should be clarified.
2. Obey the discipline, attend classes on time, check in, keep quiet, pay attention to safety, follow instructions, and pay attention to saving.
3, to operate correctly, carefully observe, actively think about problems, and make timely records.
4. According to the original record, contact the theoretical knowledge, analyze the problem in depth, carefully organize the data, and write the experimental report on time.
5, care for public property, the instrument should be inspected before and after the experiment, if there is damage in the experiment, it is necessary to register and replenish in time.
6. Solid waste such as paper dust, cotton, matchsticks, and waste liquid with strong corrosiveness and strong toxicity should be put into the waste liquid tank.
7. After the experiment is completed, the glass instrument must be cleaned, placed in order according to the original position, clean the table, clean the towel, and carry out safety inspection on the electric raft and the water raft. Finally, the waste liquid cylinder is cleaned by the value and the floor is mopped. Close the doors and windows.
