PYREX®, borosilicate glass. Heavy Duty.

• Very good chemical resistance
• High temperature resistance
• Minimal thermal expansion, giving relatively high resistance to temperature changes

Considerably more resistant to mechanical stresses than standard Erlenmeyer flasks. Designed with thick walls and an extra wide flared rim. This provides better resistance to breakage or chipping during cleaning and other uses. Extremely flat, heavy base. They are ideal for use on magnetic stirrers and hotplates. Very durable. Graduated for approximate reading of the contents, and have a white labelling area.
