Plural of beaker; cylindrical drinking glasses or measuring vessels with a flat bottom and pouring lip, commonly used in kitchens and laboratories.
From beaker (from Dutch 'beker', from Low German, ultimately from Greek 'bakcharis'). Beakers became widespread in medieval Europe and remain standard laboratory equipment.
The beaker's design—flat bottom, slanted sides, pouring lip—was so perfect that chemists and cooks have used essentially the same shape for over 1000 years with barely any changes!
