Distilling links" are specialized glassware components used in laboratory distillation setups, acting as connectors (like Claisen or Liebig types) with jackets for cooling/heating and standard joints (NS 14/23, 29/32) to join other apparatus for efficient separation, featuring connections for vacuum or water flow. They allow for precise temperature control, secure connections, and efficient heat exchange in chemical processes, from simple distillations to complex syntheses.
