Derminator® needle cartridge (9 needles)

Derminator® digital dermaneedling cartridge (9 needles). Needle diameter 0.15 mm. (38 SWG, 34½ AWG). Gamma-sterilized. The needles are made of surgical steel and do not contain nickel. This is the only cartridge that works properly with the Original Derminator®. Any other cartridges, including those for the Derminator® 2, will not fit and even if they fit, their needling depth will be incorrect.

We apologize that these cartridges appear to be worse quality (but are 100% safe!) than the previous ones - the manufacturer is unable to solve the issue and no acceptable alternative manufacturers exist - we quality-tested them all - so we sell these cartridges for less than what we paid for them, and two times cheaper than the normal price. The only issue is a purely cosmetic one: The needles are under a slight angle (about one, two degrees), which of course is of no significance, since if you would hold the cartridge under a 88 or 92 degree angle onto the skin it would have the same effect, and that effect is due to simple physics completely negligeable. In fact, not even a 35 degree slant of the needles would have the slightest negative effect. Our new Derminator 2 machine uses different, extremely high quality cartridges that are not made in China anymore and we purchased in carefully verified batches a supply for the next twelve years.

Bajonet fitting. Align the slots in the cartridge with the protrusions on the tip of the hand unit, push the cartridge on firmly and while pushing, rotate the cartridge right a quarter turn. If you don't do this, the device won't needle the set depth and the cartridge may fly off (and the magnet out). 

Cartridge lifetime depends on needling frequency, treatment duration, number of treatments and skin thickness. When treatment starts to be more painful or the machine starts to have trouble reaching the set depth, the needles have become blunt and it is time to replace the cartridge.

Cartridges should ideally NOT be reused but can be reused on only the SAME patient after disinfection with Ethanol according to our instructions. Do not use Dettol - it contains chloroxylenol, which can dislodge the needles. Chloramine-T will rust the metal spring. Disinfection procedure:

1. Blood serum removal: Pour a drop of dishwashing detergent into the cartridge and rinse it out by moving the plunger manually while holding the cartridge under a running tap with warm water.
2. Disinfection: Fill a cup with a cm of fresh, NEVER USED Ethanol, submerge the cartridge into it and move the plunger a dozen times. Let it sit overnight and the next morning, move the plunger again and let it sit some more hours.
3. Rinsing: Under tap water (tap water in the western world never contains infectious bacteria relevant to dermaneedling), operate the plunger a dozen times.
4. Drying: Re-use the cartridge only after it has fully dried out and you can see no more liquid in the mechanism or inside the silicone membrane.

The needles in this cartridge are of perfect quality. We encourage our customers to look at the tips through a strong magnifying glass and compare them to the needle tips of other brands.
