Platform
The Instant Solution™
Seamless Reconstitution + Delivery
OneMix by Windgap delivers highly soluble lyophilized drugs in two steps—automatically mixed, instantly ready, and designed for at-home or acute-use administration.
A True Two-Step Autoinjector
OneMix is purpose-built for formulations that don’t require complex mixing cycles but still benefit from streamlined reconstitution and injection.
It’s the ideal fit for:
Therapies requiring rapid activation
Highly soluble lyophilized drugs and biologics
At-home self-administration
Cold-chain sensitive formulations
Delivery settings with limited training or support infrastructure
Fewer Steps. Zero compromises.
Where other autoinjectors rely on spring-loaded or manual activation, OneMix uses gas-powered precision to ensure a confident mix, an accurate dose, and time to spare.
OneMix BY WINDGAP ELIMINATES:
Manual mixing, reconstitution, or user prep
Risk of incomplete activation or underdosing
Packaging waste from multi-part injection systems
HCP administration for otherwise self-injectable therapies
AUTOMATED Mixing

Reduction in Administration Time
In one feasibility study, the MultiMix device reduced the mixing time from 2 HOURS to a mixed and delivered dose in under 60 seconds.
Design and deliver—without the detours.
From rapid reconstitution to dual-drug delivery, our platform evolves with your pipeline.
Each Windgap platform shares a modular architecture and customizable components, so we can help you get to market faster with fewer formulation trade-offs.
