Beaker, PMP (TPX), Molded Graduations, 50mL, (Pack of 20) These superior quality Griffin beakers are ideal for all general laboratory procedures. In one beaker you can mix, measure and prepare solutions. Our Griffin beakers have a low-form and a tapered pour spout to facilitate the transferring of liquids without dripping. The heavy-duty plastic withstands repeated autoclaving. Switching from glass beakers to Globe?s plastic equivalents will greatly reduce breakage and the potential for injury.
