Class A Graduated Glass Cylinders, Batch Certified

Each cylinder is fabricated from heavy, uniform-walled borosilicate glass to maximize mechanical durability and thermal shock resistance. Calibrated "To Contain" (TC), they feature highly legible double metric scales that eliminate parallax errors by allowing researchers to read fluid levels from both directions.

Key Functional Benefits:

• Certified Class A Precision: Meets the strict volumetric tolerances of ASTM E1272, ensuring your liquid-volume measurements remain reliable and reproducible across analytical testing series.
• Calibrated to Contain (TC): Ideal for preparing precise master mixes, compounding chemical solutions, or measuring total input volume where the entire volume within the vessel must be strictly accounted for.
• Anti-Roll Hexagonal Base: The molded glass base features an ultra-stable hexagonal geometry. This design significantly lowers the vessel's center of gravity and prevents the cylinder from rolling off the bench if tipped over.
• Defensive Bumper Guards: Every cylinder comes equipped with a high-impact collar bumper guard. Positioned along the upper neck, this ring dampens shock and prevents glass-on-glass cracking if the cy
linder accidentally contacts surrounding lab hardware.
• Controlled, Drip-Free Pour Spout: A precision-formed pour spout offers stable, drip-free fluid transfer into downstream vessels, minimizing chemical splashing or sample loss.
