Plastic graduated cylinders are common precision measuring tools used in laboratories, primarily for measuring liquid volume, offering higher accuracy than measuring cups. Common materials include polypropylene (PP) or polymethylpentene (PMP), which are acid and alkali resistant and highly transparent. Capacities range from 10ml to 2000ml, and they feature a non-slip base and pouring spout. Compared to measuring cups, graduated cylinders have more closely spaced graduations, making them suitable for demanding experimental environments.
