The dual chamber cartridge pen is an innovative drug delivery device designed to store, separate, and mix two components-typically a lyophilized drug and a liquid diluent-prior to injection.
This system is ideal for biologics, peptides, and unstable formulations that require reconstitution at the point of use, ensuring maximum efficacy and extended shelf life.
How Dual Chamber Cartridge Pens Work
A dual chamber cartridge pen contains two separate compartments within a single cartridge:
Primary chamber – holds the active drug (often freeze-dried)
Secondary chamber – contains the diluent
Upon activation:
The barrier between chambers is released
The components mix automatically
The solution becomes ready for injection
This enables on-demand reconstitution, minimizing degradation risks.
