with standard ground joint angled side necks
  • Manufactured from 3.3 expansion borosilicate glass
  • The triple-neck design allows three separate components to fitted directly to the flask
  • Vertical centre neck with two angled side neck with NS 14/23 standard ground joints
  • The geometry of the flask permits very uniform heating of the flask contents
  • Tight closure due to standard ground joints
  • Fired-on, highly durable white print
Product Overview
Multi-neck flasks (two or three neck flasks) are used for a wide variety of applications where it is necessary to connect multiple components i.e. condensers, adapters, thermometers, etc., directly to the flask. Multi-neck flasks are used for wide variety of organic and inorganic chemistry applications, including distillation, fractionation and reactions of all kinds.
