The Spiral Microfluidic Mixer PDMS Master Mold is designed for casting PDMS devices that promote efficient mixing under laminar flow conditions through curved, spiral channel geometry. The spiral layout induces secondary flow effects and repeated interface stretching, enhancing mixing efficiency compared to straight-channel diffusion alone.
This master mold is ideal for microfluidic mixing studies, assay development, and flow behavior characterization, particularly in applications where compact footprint and continuous-flow mixing are required. The design supports reproducible fabrication via standard soft lithography workflows and is suitable for iterative experimentation.

Research Use Only (RUO)
This product is intended for laboratory research, engineering evaluation, and prototyping purposes only. It is not intended for diagnostic, therapeutic, medical, or clinical use, and has not been evaluated or approved for such applications.
It is not supplied with system-level validation, regulatory documentation, or safety certification for end-use devices.
 
No Performance Guarantee
Mixing efficiency, pressure drop, and flow behavior depend on user-defined experimental conditions, including fluid properties, flow rates, channel dimensions, and system configuration. No specific performance outcome or mixing efficiency is guaranteed.
User Responsibility
The user is responsible for determining the suitability of this product for their specific application, including compatibility with fluids, pressures, temperatures, PDMS formulation, and downstream equipment.
 
Material & Fabrication Compatibility Notice
Final PDMS device dimensions, surface finish, and performance depend on casting parameters, curing conditions, demolding technique, and handling. Variations are inherent to soft lithography processes. Chemical compatibility must be independently verified by the user.
