Volumetric Glassware Laboratory Operations Review 31
GLASSWARE DESCRIPTION/USE
Beaker
Erlenmeyer flask
Florence flask
Volumetric flask
Graduated cylinder (graduates)
Wide-mouthed, straight-sided jar with pouring spout. Not accurate enough for critical measurements.
Sloping sides. Graduated markings. Used to hold liquids, mix solutions, measure noncritical volumes.
Spherical base with long cylindrical neck. Single calibration mark. Only for noncritical measurements.
Pear shaped. Long neck with single calibration mark. Manufactured to strict standards. Glassware &
solutions should be at RT. Used to prepare standards & reagents. Shouldn’t be used to store solutions.
Upright, straight-sided tube with flared base. Used for noncritical measurements. Most are TD.
Shouldn’t be used to measure <5 mL or <10% of capacity. Use graduate closest in size to volume to
be measured.
