Beakers & Flasks

Find all of the beakers and flasks that you need for a chemistry science project or homeschool lab experiment. All of these glass beakers and flasks are made of high-quality borosilicate glass and can be heated over an open flame. Pyrex glassware is U.S.-made and the rest is imported, but the quality of both is very satisfactory and will withstand being heated to high temperatures over a lab burner.

Use a #6-1/2 rubber stopper with 250 ml and 500 ml flasks and Florence flasks. Use #8 rubber stoppers with 500 ml Pyrex ones. Save when you buy larger quantities of a beaker or flask!
