PYREX glass Petri dishes

Clear dishes of this level can resist repeated sterilisation (wet or dry). The edges are beaded to make mechanical strength more prominent. The bead also makes it possible to position the base and lid sidewalls equally thereby reducing the capillary action of heavy moisture on the slides. These are not chemically or thermally effected by any of the methods that are commonly used in research laboratories where sterilisation is a significant part of routine or specialised work. The covered dish isn't airtight.

The tops are arranged in blue polish and the bottoms are arranged in white polish to facilitate arrangement. Bottoms also have a triangular, polished point of reference for serial dilutions.

Available in 60mm, 100mm and 150mm diameter.

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 230°C. PYREX volumetric labware can be brought to 150°C. 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 160°C.

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.
