Volumetric Flask, 5 mL / ±0.02 mL Tolerance (CAT#: STEM-AL2-5992-ZJF)

The Volumetric Flask is designed for preparation and dilution of solutions to a defined laboratory volume. Its narrow neck carries a calibration line that identifies the nominal volume at the specified calibration condition. The vessel uses a pear-shaped flask body with a flat or supported base and a fitted glass stopper as described in the source. This configuration has a nominal capacity of 5 mL. The stated tolerance defines the source-specified volumetric accuracy for this capacity. The stopper size is specified to support consistent closure and matching of the glass joint. The clear glass format supports direct visual observation of the solution and calibration line. The flask is intended for analytical chemistry, standard-solution preparation, dilution, and routine quantitative laboratory work.
