Corning PYREX Watch Glass - Assorted Sizes

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 and 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.
