WebLocate 250-mL Erlenmeyer flasks. If they are not dry, use a rolled-up piece of paper towel and a glass stir rod (be careful!). Weigh the dry empty flasks on the analytical balance. With the 25-mL pipet to be calibrated, carefully deliver the measured volume of distilled water into the flask. Allow 20 seconds for the pipet to drain. WebBoiling flasks are round in shape and come with both flat and rounded bottoms. The ones with round bottoms will, of course, need external support to stay upright. The boiling flasks are used to heat chemicals inside. They are made of borosilicate glass; it is a good heat conductor while strong enough not to melt due to the heat.
