These Watch Glasses provide high chemical durability, preventing contamination of solutions. They are modeled to the same radius of curvature for convenient stacking. The heavy wall an uniform fire-polished edge provide mechanical strength. The outside diameter cannot be controlled within close limits and a slight degree of out-of-round can be expected to occur.
