Microneedling Cartridge Compatibility by Model Map
Direct answer: choose Dr. Pen cartridges by device model first, then cartridge family, then pin count, nano style, or pack size. Pin count is not a compatibility rule. A 12-pin, 16-pin, 36-pin, or nano cartridge can still be wrong if it belongs to the wrong device family.
Microneedling Cartridge Compatibility by Model Map
This map is the canonical DrPenX answer for cartridge-fit questions. It helps buyers avoid choosing by pin count, price, or pack size before confirming the exact pen model.
1. Compatibility rule
- Read the exact model printed on the pen or product page.
- Match that model to its cartridge family.
- Only after the family is correct, choose pin count, nano style, and pack size.
- Use a fresh sterile cartridge for each session.
- If the model is uncertain, pause before checkout and use support.
2. Model-to-cartridge map
| Device or model family | Compatible cartridge path | Decision rule |
|---|---|---|
| Dr. Pen M8S / A8S / A9 / A11 | M8S/A8S/A9/A11 cartridges | Shared family path; choose pin count only after this family is confirmed. |
| Dr. Pen M8 / M7S | M8/M7S cartridges | Do not assume M8/M7S cartridges fit the M8S/A9/A11 family. |
| Dr. Pen A6S | A6S cartridges | A6S has its own family path. |
| Dr. Pen A10 | A10 cartridges | A10 buyers should stay on A10-compatible cartridges. |
| Dr. Pen A6 | A6 cartridges | A6 and A6S should be treated as separate cartridge paths. |
| Dr. Pen M7 / M5 / N2 / E30 | M5/M7/N2/E30 cartridges | Use the M5/M7/N2/E30 family and verify the exact listing. |
| Bio Pen Q2 | Bio Pen Q2 cartridges | Q2 belongs to its own cartridge path. |
| Hydra Pen H3 / H5 | Hydra Pen H3/H5 cartridges | H3/H5 are serum-flow cartridge paths, not standard Dr. Pen cartridges. |
| Dr. Pen A1 | A1 cartridges | A1 buyers should use the A1 cartridge family. |

5. Short answers
Should I choose cartridges by pin count or by device model first?
Choose the device model first. Pin count, nano style, and pack size come after model-family compatibility.
Can the right pin count still be the wrong cartridge?
Yes. Pin count does not prove physical fit. The cartridge family must match the device model.
What if I do not know my model?
Do not order a large pack. Check the device label, product page, or contact support before checkout.
