5mL Class A Borosilicate Graduated Cylinder, ASTM E1272, Batch Certificate Included
The Globe Glass™ 5mL Class A Graduated Cylinder (8300005) covers the measurement range most prone to volumetric error when using 10mL cylinders — providing Class A calibration tolerance and ASTM E1272 certification with a batch calibration certificate at the volume most critical for preparing low-concentration standards, titrant solutions, and reference dilutions in pharmaceutical QC, analytical chemistry, and regulated research environments. The solid hexagonal base prevents tipping on vibrating surfaces and in crowded bench setups, and the included PE bumper guard provides impact protection without a separate stand.
Key features
- Class A calibration tolerance at 5mL — the tightest available — delivers ±0.05mL accuracy that makes a measurable difference in low-volume standard preparation, where a 1% volumetric error in a 5mL transfer propagates directly into assay results in regulated applications
- Batch calibration certificate ships with each cylinder, providing the lot-traceable documentation required for ISO 17025-accredited labs, FDA 21 CFR Part 211 compliance, and USP volumetric glassware qualification without sourcing a separate certificate
- Solid hexagonal base provides lateral stability on vibrating instruments, uneven bench surfaces, and in crowded setups where round-base cylinders tip — the hexagonal geometry also prevents the cylinder from rolling when set down on its side during workflow
- ASTM E1272 Style 1 TD calibration — "To Deliver" — means the graduation marks account for liquid retained on the glass wall, so the delivered volume matches the marked graduation without correction factors

Applications
Used in pharmaceutical QC, analytical chemistry, environmental testing, and university research labs for preparing low-volume reference standards, titrant solutions, and serial dilutions where the 5mL graduated cylinder provides accuracy that 10mL cylinders cannot match at this volume. The included batch certificate satisfies volumetric equipment qualification documentation requirements in GMP, ISO 17025, and FDA-regulated analytical environments without additional sourcing steps.
