scientificity
Scientificality is the first principle in the design of laboratory decoration scheme. The so-called scientific nature means that the experimental principles, procedures and methods should be correct. In the operation procedure, a small amount of solid should be dissolved first, and then a small amount of prepared solution should be taken and added with reagents, so it is impossible to completely dissolve the sample or add reagents to all dissolved solutions.
safe
When designing SICOLAB for experimental decoration, toxic drugs and dangerous experimental operations should be avoided as far as possible. If it must be used, it should be noted in detail in the designed experimental scheme to prevent environmental pollution and personal injury.
feasibility
The experimental decoration design of SICOLAB should be as practical as possible, and the selected chemicals, instruments, equipment and methods can meet the existing experimental conditions in middle schools.
simple
The experimental decoration design of SICOLAB is as simple as possible, the experimental device is simple, the experimental steps and drugs are few, and the experiment can be completed in a short time.
