How are pipette tips manufactured?

view 783

The process of making a pipette tip can vary from manufacturer to manufacturer, however, the basic principles remain largely the same. The process of manufacturing a plastic pipette tip with a long capillary in front involves the following steps:

  1. Injection molding of a pipette tip in a mold. 
  2. Opening of the mold and drawing the plastic section into a capillary.
  3. The unsolidified plastic section is selectively heated. 
  4. The tip is drawn vertically, and the tip is shaped using a molding element.
