Material: Borosilicate glass with strong resistance to acids and alkalis; washable with cleaning agents and suitable for repeated use. Key benefits - Chemical compatibility: resistant to acids, alkalis and many common solvents, making it suitable for lab and hobby projects. - Thermal performance: borosilicate glass tolerates heating and rapid temperature changes. - Easy to use: simply add material and apply heat; adapts to quick temperature changes with low-temperature adjustments. - Safe heating guidance: for even heating, place a heat-diffusing screen or wire mesh under the beaker. - Practical limits: when dissolving, keep liquid to no more than 1/3 of the beaker volume; avoid touching the bottom or walls with the stirring tool. - Safety for corrosive liquids: when heating corrosive chemicals, cover the mouth with a watch glass to prevent splashing. Instructions Place the material inside and heat. The beaker is designed to handle rapid temperature changes and cooling. Versatility and applications - Lab use: measuring and handling epoxy resin, paint and other liquids, with good acid/alkali resistance and compatibility with common solvents. - Kitchen or culinary experiments: precise liquid measurement and controlled heating for recipes and demonstrations. - DIY and educational projects: suitable for staining, coating, or solvent-based liquid experiments in various settings. Note: Do not exceed the 1/3 liquid volume guideline during dissolution; stir carefully and avoid contact with the beaker bottom or walls while stirring. Cover the mouth with a watch glass when heating corrosive substances.
