Graduated Cylinder Set — 5 Sizes: 10/25/50/100/250mL, Borosilicate Glass

Volumetric accuracy starts with the right cylinder: the graduated cylinder is calibrated to within 1% tolerance, far exceeding the ±5% of a beaker or flask.

The tall, narrow form minimizes the meniscus-to-diameter ratio, making readings straightforward even without a magnifying lens. Hex base prevents rolling; blue enamel graduations are fired into the glass surface for permanence — they won't wash off with solvents. Calibrated "to contain" (TC) at 20°C per ISO 4788.

• Set of 5: 10mL, 25mL, 50mL, 100mL, 250mL borosilicate cylinders
• ±1% volume accuracy — ISO 4788 Class B tolerances
• Hex base with pour spout; permanently enamelled blue graduations
• Autoclave-safe; resists all common laboratory solvents
