Volumetric Measurement & Analytical Titration

Xin Tester Glass Graduated Cylinder (25mL & 50mL Class A)

Inaccurate graduated glassware introduces systematic volumetric compounding errors across scientific titrations and standard preparation. The Xin Tester 25mL and 50mL graduated measuring cylinders are precision-calibrated to deliver (‘Ex’) at 20°C in compliance with ISO 4788 Class A standards. Fabricated from thick-wall 3.3 borosilicate glass, they resist aggressive solvents and accidental workbench knocks. Explore our complete selections in the Lab Glassware catalog.

Permanent Ceramic Graduation

The blue enamel graduation lines and numbers are fired into the glass surface permanently. They remain fully legible even after repeated washings in chromic acid or alkaline lab dishwashers.

Hexagonal Glass Footing

Unlike round-base cylinders that topple easily when placed on crowded benches, the hexagonal base distributes center of mass broadly and prevents rolling if tipped over onto worktops.

Graduation Specifications

The 25mL cylinder features 0.5mL sub-divisions (±0.25mL tolerance); the 50mL cylinder features 1.0mL sub-divisions (±0.50mL tolerance). Always read liquid meniscus at eye level.

FAQs

Each Xin Tester cylinder is calibrated “to deliver” at 20°C using strict quality control. We use precision instruments to verify every unit before packing, so you receive a cylinder that meets ISO-grade accuracy standards. Plus, the clear markings and meniscus-friendly glass make reading easy – reducing human error as well.

BORO 3.3 high borosilicate glass offers superior thermal shock resistance (can withstand sudden temperature changes), high chemical durability against acids and alkalis, and excellent optical clarity. It is more robust and longer-lasting than soda-lime glass, making it ideal for regular laboratory use.

Always bring your eye level to the same height as the liquid’s meniscus (the curved surface). For transparent liquids, read the bottom of the meniscus at the lowest point. Ensure the cylinder is placed on a flat, stable surface and that the graduations are clearly visible. Consistent reading technique is key to reliable results.

BORO 3.3 glass has good thermal resistance, but direct heating (e.g., on a Bunsen burner or hot plate) is not recommended as it may cause uneven expansion and cracking. For sterilization, autoclaving at 121°C is generally acceptable – always check the specific product markings and allow gradual temperature changes to avoid thermal shock.
