Instructions for use – MicronJetTM


  • Hold syringe flanges between thumb and fingers
  • The blue line must face you at all times
  • Syringe flanges are not the orientation guide as they may not always be parallel to the blue line; use the blue line for orientation


  • Stretch the skin downwards throughout the entire injection
  • Insert the device at a 45° angle
  • Press the device into the skin until a shllow indentation is formed


  • Inject slowly, expect strong resistance
  • A white wheal (bleb) will form at the injection site
  • Upon completion, wait 3 seconds and remove syringe

In case of leakage, follow the common practice as with a regular needle and syringe

Factors that result in major leakage:

  • Injection may have started out wet – avoid pressing the plunger prior to injection
  • Syringe not held properly – make sure you hold the syringe flanges between fingers and thumb; avoid switching hands
  • Improper device orientation – make sure blue line faces you during injection
  • Syringe is not tilted sideways or rotated
  • Too high / low injection angle – make sure angle between syringe axis and skin surface is as close as possible to 45˚
  • Insufficient pressure applied to the skin – increase slightly
  • Skin not stretched – make sure to keep the skin stretched throughout the entire injection

Effects of small/no bleb without leakage:

  • Large air bubble within syringe – make sure to fill syringe properly and remove air bubbles
  • The fluid is leaking between the device and the syringe – make sure you firmly connect the device to the syringe

The causes of high injection pressure:

  •  Too much pressure is applied to the skin – reduce slightly
  • Improper injection angle – too high. Make sure angle between syringe axis and skin surface is as close as possible to 45˚
  • Skin type or texture – try different injection site
