Dual-chamber anatomy

Dual-chamber vial with powder and solvent chambers beside its plunger

Sterile solvent sealed above the stopper, kept fully separate from the powder until use.

Contamination-control principles

A closed barrier from filling to activation.

Standard vial

A butyl stopper and crimped cap protect the lyophilized fill. Reconstitution requires a separate controlled transfer.

Single-chamber cartridge

One sealed chamber holds the prepared fill; stopper integrity, device fit and materials compatibility are checked for the intended format.

Dual-chamber system

A bypass stopper separates solvent from powder until activation, reducing separate transfer steps. Container closure and sterility require validated manufacturing controls.
