Snuff Back

No dripping no pull back
  • Snuff back vacuum controlls the vacuum level in respect to fill level

To avoid uncontrolled dripping of material from the dispensing tip the option Snuff Back is available.  This is especially important when dealing with low viscosities (ie thin liquids).  The amount of material in the syringe significantly affects this aspect. Too much vacuum can lead the material being pulled back into the dispensing tip and possibly causing the generation of air bubbles.  This challenge is automatically addressed by the self regulating Snuff Back function in CLEVER-DISPENSE units after a single set up.  Repeatable, clean dispensing results are achieved with rare blockages for the complete syringe filing.
