Beakers are like books - you can never have too many! Our stackable, economical plastic beaker set is just right for nearly any scientific task that doesn't require extreme heat. Five sturdy polypropylene beakers come in convenient sizes of 50 ml, 100 ml, 250 ml, 500 ml, and 1000 ml. Best of all, they stack together to take up less storage. Graduated measurements are raised on the beakers so they won't fade or wash off.
