6PK Plastic Beakers, 250ml - Polypropylene - Raised Graduations

This six-pack contains 250mL beakers in translucent polypropylene with raised graduations marked every 10mL. The graduations are molded into the wall rather than printed on it, so they cannot wear off through repeated autoclaving or abrasive cleaning. Each beaker has a tapered spout for controlled pouring, measures 3.9 inches tall and 2.8 inches in diameter with an inner diameter of 2.7 inches, and offers enough optical clarity to read liquid levels through the wall. Polypropylene will not shatter if a beaker is dropped, which suits school laboratories, fieldwork, and any setting where broken glass is a hazard. The beakers are microwavable and autoclavable, with chemical durability across common reagents and a working range from -20°C to 135°C. That upper limit rules out direct flame or hot plate heating.
