noun
measuring cylinder; graduated cylinder
A tall, narrow container with volume markings, used in laboratories to measure liquids.
from German Messzylinder
実験でメスシリンダーを使って水の体積を測った。
I measured the volume of water using a graduated cylinder in the experiment.
A beaker is a wide-mouthed container for mixing and heating, while a メスシリンダー is specifically for precise volume measurement.
A flask is used for reactions and storage, often with a narrow neck; a メスシリンダー is for measuring, not for reactions.
Borrowed from German 'Messzylinder' (measuring cylinder).
