Heavy-duty Glassware Guide

The Pyrex® heavy-duty glassware is designed to offer optimal mechanical resistance in the most demanding laboratory conditions. Designed to withstand intensive use more effectively than other laboratory glassware, our high-strength beakers, Erlenmeyer flasks, and test tubes benefit from unique features that allow them to be reinforced in areas where it is particularly important to do so. Containing more glass than standard beakers, flasks, and test tubes, our heavy-duty Pyrex® glassware is particularly impact-resistant. The glass is less prone to cracking and shattering. It wears out less quickly and therefore has a longer lifespan.
