PATIKIL Watch Glass Set (60-150mm)

This set of four transparent glass watch glasses is ideal for laboratory use, including drop culture tests, beaker covers, and temporary storage of liquid and solid samples. Made from high chemical durability table glass, they offer corrosion resistance to maintain material purity and increase liquid surface area for faster evaporation. Recommended to wash and dry before and after use for accurate experimental results. Note: Do not heat directly with fire or use as an evaporation dish.
