A dual-chamber vial stores sterile solvent above a bypass stopper and the lyophilized cake below. One press of the plunger opens the bypass and the contents mix in seconds.
For brand owners the appeal is presentation and consistency: no separate solvent vial, fewer handling steps and a premium unboxing experience.
Compatibility is confirmed per compound before filling, and the format adds a transparent +$100 per kit over standard vials.
