Double Scale Measuring Cylinders (TD), Individually Certified

United Scientific Individually Certified Double Scale Measuring Cylinders are built for accurate, dependable liquid measurement in analytical, research, educational, and quality control laboratories. Each cylinder meets ASTM E1272 Class A standards and is individually serialized and certified, giving labs item-level traceability for regulated, audit-ready, or quality-critical workflows.

Made from heavy-duty borosilicate 3.3 glass, these cylinders feature a double metric scale, pour spout, heavy uniform wall tubing, and an attached glass hexagonal base for stability. They’re calibrated to deliver, include an adjustable PP bumper guard for added protection, and are supplied with individually certified documentation and a Certificate of Conformity.
