This polypropylene measuring volume set includes three beakers (50mL, 100mL, and 250mL), four graduated cylinders (10mL, 25mL, 100mL, and 250mL), and one 500mL pitcher with spout — eight pieces total covering the most commonly used volumes for introductory measurement work. All pieces are made from durable polypropylene, which resists shattering if dropped and holds up to repeated use in classroom and home lab settings. The graduated markings are raised directly into the plastic, making them easy to read and resistant to wear over time. All vessels are calibrated to contain (TC). This set is well suited for science projects, homeschool labs, and any setting where students are learning volume measurement and liquid handling fundamentals without the breakage risk of glass.
