Two Neck Round Bottom Flask

This two-neck round-bottom flask provides two access points for building compatible laboratory reaction, reflux and distillation setups. Its spherical body holds the reaction mixture, while the separate necks allow suitable apparatus to be connected as your method requires.

Use one neck for a compatible condenser or adapter and the other for an appropriate addition or monitoring accessory. Match the flask's joint sizes to your equipment before assembling the setup.
