These round bottom boiling flasks have a single rimmed neck (also called a beaded rim) and are made from quality borosilicate 3.3 heat-resistant glass.

Key Features

  • Even heating: The spherical bottom spreads heat evenly. Because it's round, the flask needs a cork ring, clamp or heating mantle to stand.
  • Containment: The narrow neck reduces evaporation and the risk of splashing when you swirl the contents.
  • Material: Borosilicate 3.3 glass, with high thermal shock resistance and chemical durability.
  • Rimmed (beaded) opening: A reinforced, fire-polished rim that resists chipping and helps stoppers fit securely.
  • Design: Spherical round bottom with a single narrow neck and reinforced beaded rim.
  • Standards: Made in line with IS 1381 and ISO 1773.

Flat Bottom vs Round Bottom

Both are used for heating, but they suit different jobs:

  • Flat bottom: Best for storage, mixing and routine boiling on hot plates. They're easier to use in schools because they stand without clamps or cork rings.
  • Round bottom: Preferred for distillation and reflux, because the spherical shape heats more evenly and handles pressure better.
