Single-use A7 refill format.
Keep the component sealed until installation, inspect it for damage, and dispose of it after one session for one person.
Before opening
Four checks,
every time.
- 01Confirm the device
Read the complete model name on the device or package. Similar names, colors, or connector shapes do not prove compatibility.
- 02Inspect the package
Use a new, individually sealed cartridge only when its package, body, and contact surface are undamaged.
- 03Install as directed
Keep the device powered off and follow the supplied instructions. Never force a component that does not align correctly.
- 04Use once, then dispose
Do not share, wash, reprocess, or reuse a cartridge. Dispose of it according to local requirements.
Important
Pin count identifies the SKU; it does not establish a universal speed, depth, frequency, or treatment purpose. Available format names are purchasing identifiers, not medical or treatment advice.
Cartridge FAQ
Before you choose.
