White label pens, single and dual chamber
Your colours, logo and box on an injection pen. The product decides the format: a stable liquid goes in a single cartridge, and a powder needs two chambers.

How the two formats differ
| Item | Single chamber | Dual chamber |
|---|---|---|
| Best for | A product that stays stable as a liquid | A product that has to stay dry until it is used |
| Cartridge | 3 mL glass cartridge, one chamber | Glass cartridge with two chambers and a bypass |
| Inside | Liquid, ready as supplied | Powder in front, diluent behind |
| First step | None | Twist once to mix |
| Stoppers | One | Two, plus the seal at the neck |
| Filling | Cartridge filling line | Specialist line that freeze dries inside the cartridge, so few plants can do it |
