Precision volumetric flasks

  • with standard ground joint stopper made of polypropylene, class A - borosilicate glass 3.3
  • with standard ground joint stopper made of polypropylene, class A - polymethylpentene (PMP)
  • with standard ground joint stopper made of polypropylene, class B - polypropylene (PP)
  • The narrow neck of the flask ensures high filling accuracy
  • To protect the printed markings, clean at temperatures up to 60°C
  • Autoclavable at +121 °C

In the laboratory

  • For measuring different volumes of liquids
  • For preparing or storing solutions with specific concentrations

Misappropriated Use

  • As a decorative bottle, e.g., for vinegar or oil

Volumetric flasks are not graduated with a scale. Therefore, a specified quantity of solution must always be prepared. Alongside volumetric pipettes and burettes, volumetric flasks are among the most accurate volume-measuring devices.
Volumetric flasks have a single calibration mark on the narrow neck, which is marked as a ring encircling the neck. This design helps prevent reading errors. The narrow neck allows for precise volume measurements. The correct volume is achieved when the lower meniscus (curve) of the liquid touches the ring mark. Maximum accuracy is obtained only if no gas bubbles are present in the liquid. Gently swirling the flask allows any gas bubbles to rise to the surface.
Borosilicate glass volumetric flasks are calibrated for pouring, meaning the volume of the liquid inside corresponds to the specified volume. However, when transferring the liquid to another container, the volume will be slightly less, as a small amount remains in the flask.
Heating volumetric flasks can lead to a loss of measurement accuracy.
