Volumetric Flask

Pear-shaped flask calibrated to contain one exact volume at the etched line, defining solution molarity.

Core Principles & Analysis

• It is calibrated "to contain" a single volume at a marked line and stated temperature, usually 20 °C.
• Class A glassware tolerances are roughly a tenth of a percent.
• Reading the bottom of the meniscus at eye level is the technique every chemist learns first.

Specifications & Metrics

• MEASURES: Fixed volume (±0.1% class A)
