Heathrow Scientific Borosilicate Glass Graduated Cylinders - 2351 Series

Execute highly accurate liquid volume measurements with the Heathrow Scientific Borosilicate Glass Graduated Cylinders (2351 Series). Manufactured from premium-grade, chemically resistant borosilicate glass, these reusable laboratory cylinders are engineered to withstand extreme thermal shock and exposure to harsh industrial solvents. Designed to exceed stringent ASTM E-1272 standards, they are expertly calibrated "To Contain" (TC) specific volumes at the industry-standard 20°C (68°F).

To guarantee long-term durability in high-traffic laboratory environments, each cylinder features a heavy-duty, anti-roll hexagonal base that provides superior vertical stability, drastically reducing the risk of tipping and spilling. The highly visible, permanent white enamel graduation markings will not fade or wear off during repeated autoclaving or aggressive chemical cleaning. Additionally, all cylinders in this series come equipped with a removable protective bumper guard to further prevent breakage if the cylinder is accidentally knocked over.

Features & Benefits
