1. High-temperature Stability: Capable of withstanding high-temperature circumstances and usually applicable under the common heating conditions in laboratories.
2. Thermal Shock Tolerance: Exhibiting favorable thermal shock tolerance and being suitable for experiments that demand rapid heating or cooling.
3. Chemical Stability: Manufactured from non-alkaline soda-lime glass, it demonstrates a remarkable level of corrosion resistance towards the majority of chemical reagents, encompassing common acids, bases, organic solvents, etc.
4. Insolubility: In chemical reactions, the glass beads do not dissolve or release any chemical substances, and will not cause interference or contamination to the experimental system.
5. Smooth Surface: The surface is sleek and even, with a low propensity to adsorb chemical substances, facilitating cleaning and reuse.
6. Low Friction Coefficient: Possessing a relatively low friction coefficient, when in contact with other substances during experiments, it can reduce wear and the heat generated by friction, contributing to maintaining the stability of the experimental environment.

1. Choose the appropriate specification: Select in accordance with the experimental demands. Different experiments have distinct requirements for the size and shape of the glass beads.
2. Ensure homogeneity: Select glass beads of uniform size to guarantee the consistency and reproducibility of the experimental results.
3. Cleaning and disinfection: Before usage, ensure the surface of the glass beads is clean to prevent residual chemical substances from influencing the experimental results. After usage, they should also be promptly cleaned to remove adhered chemical substances or samples.
4. Add in an appropriate amount: Add an appropriate quantity of glass beads based on the size of the flask and the volume of the liquid.
