Borosilicate 3.3 glass, with spout.

• Good chemical and thermal shock resistance
• Durable labelling area with matt finish and white graduated scale
• Spout designed for optimum performance

Heavy-duty beakers have better mechanical stability than the standard products due to thicker walls. The reinforced rims increase shock resistance and reduce the risk of breakage. Due to the increased wall thickness resistance to rapid temperature changes is not as good as that of the standard product, therefore, slow, uniform heating is recommended.
