PYREX glass beakers, low form

Manufactured with uniform wall thicknesses, these beakers offer the optimum balance between thermal shock resistance and mechanical strength.

The 250, 400 and 600ml sizes have a double graduated scale to indicate approximate volume.

All sizes have an extra large marking spot.

Designed from ASTM Specification E960, Type I requirements.

Glassware Standards

PYREX Labware is designed to meet the rigorous demands of scientific experimentation. In fact, these scientific glassware products were integral in developing penicillin during World War II and the polio vaccine during the 1950s.

PYREX glass is well-suited for lab work with used borosilicate to produce beakers, flasks, test tubes, and other lab glassware. PYREX lab glassware made with borosilicate can withstand harsh, corrosive chemicals, handle extremely low and high temperatures, and it can survive rapid temperature changes without sustaining damage. PYREX beakers, Erlenmeyer flasks, and round- and flat-bottom boiling flasks can be repeatedly heated up to 230ºC. PYREX volumetric labware can be brought to 150ºC. PYREX laboratory glassware has a temperature shock limit (or allowable difference between the temperature of the glass and any medium in contact with the glass - air, liquid, or solid) of 160ºC.

Always check laboratory glassware for any cracks, scratches, chips, or hazing as these damages can cause the product to break while in use. If properly cleaned and not damaged, PYREX laboratory glassware is reusable.
