Useful Tips of using Duo-Gun:

  • Disposable gun tips are designed for one-time use only. Before using it for the first time, autoclave it at 121°C for 30 minutes and dry at room temperature for 30 minutes.
  • Always use the provided Multi-Purpose Wrench to attach, remove and bend the Duo-Gun. Do not use hand.
  • After each use, remove all visible leftover gutta percha obturator in the heat chamber with the scrubbing brush. Melt the residual at 160°C and clean it out with the scrubbing brush.
  • Use only one gutta percha obturator pellet at one time. Too many pellets can damage the device.
  • Refer to the Duo-Gun Manual for more useful tips!
