This 600ml Bomex beaker meets ASTME-960 Type 1 Specifications for Classification, Design, Capacity, Dimensions, and Markings. It features an easy-pour spout with white permanent graduations and a large marking square.
Bomex beakers are made from quality borosilicate glass. As an import, it is less expensive than Corning-made Pyrex. We have noticed variation of wall thickness and make a suggestive comment that Pyrex uniformity might be preferable if using higher heat.
