This set of experimental equipment includes various metal materials such as crucible tongs, tweezers, medicine spoons, etc. These tools are mostly made of stainless steel and have the characteristics of corrosion resistance and high strength, suitable for different operational needs in chemical experiments. Crucible pliers are used to hold high-temperature crucibles; Tweezers can accurately pick up solid reagents or small instruments; The medicine spoon is used to retrieve powdered or small granular medicines. This set of tools is crucial in chemistry experiment teaching, helping students to operate in a standardized manner, ensuring experimental safety and accuracy, and serving as a key medium connecting theoretical knowledge with experimental practice.
