The
MULTIMIX
Platform
Difficult to Mix?
Consider it handled.
MultiMix by Windgap automates the mixing and reconstitution of complex drug formulations—delivering a ready-to-inject therapy with just two simple steps.
Designed to meet your molecule where it is.
Multimix by Windgap is a highly customizable platform specifically designed to simplify, automate, and accelerate complex drug delivery, specifically for:
mAbs
Sustained release formulations
Shear-sensitive biologics
Lyophilized drugs & suspensions
High-viscosity therapeutics (>5,000 cPs)
Formulating a drug that works is hard enough. Delivering it shouldn’t be.
Formulating a therapy takes years of science—delivering it shouldn’t take work, waiting, or a trip to the clinic.
Yet sensitive biologics and stubborn suspensions can add steps, force delays, and keep patients dependent on healthcare providers.
MULTIMIX BY WINDGAP ELIMINATES:
Complicated manual reconstitution with intricate steps and wasteful packaging
Shaking and mixing errors that decrease drug efficacy and patient compliance
Compatibility issues with large molecules or viscous drugs
In-clinic administration for otherwise self-injectable therapies
AUTOMATED Mixing
FASTER ADMINISTRATION

Feasibility-backed. Partner-approved.
Windgap has 105+ patents issued and is trusted by the top 25 pharma partners for delivering innovative solutions.
75 cP suspension delivered through a 29 XTW cannula
First demonstrated delivery of this drug through such a small needle.
99%
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.
