Measuring Cylinders Hexagonal

Raised prominent graduations are molded directly into the cylinder surface, creating permanent markings that will never wear off, fade, or become illegible—unlike printed graduations that can be worn away by cleaning, autoclaving, or chemical exposure. This ensures that your measurements remain accurate and the cylinder remains usable for its entire lifetime.

The hexagonal base provides six flat sides that create a wide, stable footprint, preventing the cylinder from tipping over. Round-base cylinders can easily roll off benches or tip if bumped. The hexagonal design is particularly important for larger cylinders (500ml-2000ml) that become top-heavy when filled, and enhances safety when working with valuable or hazardous liquids.

This certification indicates that the polypropylene material meets the requirements of the US Food and Drug Administration regulation 21 CFR, which governs materials that may come into contact with food, pharmaceuticals, and laboratory samples. For measuring cylinders, this ensures that no harmful substances will leach into your solutions, maintaining sample integrity and meeting regulatory requirements for pharmaceutical and food testing.

Yes, these polypropylene measuring cylinders are fully autoclavable at standard sterilization temperatures (121°C). They can be repeatedly autoclaved for sterile applications and decontamination. The raised graduations and structural integrity are maintained through multiple autoclave cycles.

Polypropylene offers excellent resistance to a wide range of laboratory chemicals including aqueous solutions, dilute and many concentrated acids and bases, alcohols, and many organic solvents. For specific chemical compatibility with your reagents, consult standard polypropylene resistance charts.

These hexagonal measuring cylinders combine multiple features that make them exceptional: FDA-compliant polypropylene for material safety; single-piece construction for durability; raised prominent graduations for permanent legibility; excellent clarity for accurate meniscus reading; stable hexagonal base for safety; efficient tapered spout for controlled pouring; eight size options for comprehensive coverage; autoclavable for sterility; chemical resistant for versatility; unbreakable for safety; and economical pack quantities for value. This comprehensive design, focused on accuracy, safety, and durability, makes these cylinders the best choice and the top rated solution for laboratory liquid measurement.
