Touch ‘n Heat 5004 Model #5004, Endodontic Heat Source, 110v, Single Unit. Consistent and convenient chairside heating system for warm gutta percha techniques. Safer, faster and more consistent than open flames or Bunsen burners. Complete control over the heat level, the tip is heated precisely to the setting. The autoclavable tips are internally heated, so heat is concentrated at the end of the tip, where it’s needed most. Rechargeable battery carries a 45-minute charge.
