Application Summary AI generated
This standard specifies the dimensions, tolerances, and technical requirements for two-neck and three-neck spherical round-bottom flasks made of laboratory glassware. It is applied in chemical laboratories and research institutions for conducting reactions that require multiple inlets, such as adding reagents, connecting condensers, or inserting thermometers under controlled conditions. The standard ensures interchangeability and compatibility with other laboratory apparatus, particularly in synthetic chemistry and distillation setups.
