PYREX® Watch Glasses

PYREX® borosilicate glass.

• High chemical durability
• Prevents contamination of solutions

These watch glasses are molded to the same radius of curvature for convenient stacking. The heavy wall and uniform fire-polished edge provides the mechanical strength. The outside diameter cannot be controlled within close limits and a slight degree of out-of-round can be expected.

They are also used as covers for heated beakers.

Emballage: One package has 12 watch glasses.
