Dr. Pen M9 cartridges are single-use, chip-embedded bayonet needle cartridges made exclusively for the Dr. Pen M9 microneedling pen.
Each box holds 10 cartridges in one needle configuration 18-pin, 36-pin, 42-pin or Round Nano with 0.18 mm surgical-grade stainless steel needles, an anti-backflow valve and a triple-lock needle carrier for clean, stable collagen induction and serum infusion treatments.
Key Benefits of Dr Pen M9 Needle Cartridges
- Hygienic, one-client use: The anti-backflow valve blocks the reverse flow of serum and fluid into the handpiece, helping prevent cross-contamination.
- Better serum absorption: The serrated tip stays in contact with the skin so serums remain in the treatment zone.
- Stable needling: A triple-lock needle design holds the needle module steady for smooth, even passes.
- Intelligent chip recognition: An embedded chip links the cartridge to the M9 through contact points on the bayonet head.
- Adjustable depth: Needle depth is set on the M9 pen, so one cartridge type covers multiple protocols.
- Easy-to-stock box of 10: A practical quantity for clinics, mobile therapists and training rooms.
Features : Dr. Pen M9 Microneedling Cartridge
Anti-Backflow Valve With Air-Pressure Release
An internal valve stops serum, blood and fluid from travelling back up into the pen, while an air-pressure release keeps the needle stroke smooth. This protects the M9 motor and supports safe, hygienic practice.
Serrated-Tip Skin Contact
The scalloped front edge glides across the skin while keeping contact, improving serum absorption through the micro-channels created during treatment.
Triple-Lock Needle Design
Three locking points secure the needle carrier inside the clear housing, delivering steady, consistent penetration across the treatment area.
Chip-Embedded Bayonet Connection
The cartridge twists onto the M9 nose with a bayonet fitting. Metal contact points on the head connect the embedded chip to the pen for intelligent cartridge recognition.
