The
MULTIMIX
Platform
Difficult to Mix?
Consider it handled. Single-handedly.
MultiMix by Windgap automates the mixing and reconstitution of complex drug formulations—delivering a ready-to-inject therapy with in the press of a button.
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 AUTOMATES + ACCELERATES COMPLEX DRUG DELIVERY | ||
|---|---|---|
| ⛔️ Manual reconstitution with multiple steps | → | ✅ Automatic, single-button activation |
| ⛔️ Shaking and mixing errors | → | ✅ Consistent, validatable mixing every time |
| ⛔️ Compatibility challenges with large or viscous molecules | → | ✅ Optimized mixing for a wide range of viscosity and volumes |
| ⛔️ In-clinic administration | → | ✅ Reliable, at-home self-injection |
| ⛔️ Vertical orientation requirements | → | ✅ Mixing and injection at ANY angle |
