Borosil Graduated Cylinders

Borosil® Class A TC Graduated Cylinders provide users with the utmost quality in graduated glassware.

Each cylinder is individually calibrated by automatic, laser-controlled calibration equipment in an ISO/IEC 17025:2005 accredited calibration facility. Then, each cylinder is engraved with a unique serial number, allowing users to download individual certificates from Borosil's website,, or by downloading the Borosil app on their smartphone or tablet.

Borosil® Cylinders are manufactured with hexagonal bases for improved stability, and the bases are aligned with the pouring spout such that the spout is protected in case of tipping.

Borosil® Cylinders use the same 3.3 Low-Expansion Borosilicate found in other Borosil® products, and are designed with thick, sturdy walls for repeated, long-term use. Permanent amber graduations will not fade or disappear even after years of use.

Available in sizes ranging from 5mL to 2L. Borosil® Class A TC Graduated Cylinders comply with ASTM E-1272 specifications.
