The Microfluidic Gradient Generator PDMS Master Mold is a precision-engineered mold designed for casting PDMS devices capable of generating stable, spatially controlled concentration gradients under laminar flow conditions. Featuring an extended microchannel network, this design enables smooth gradient formation across a large interaction length, making it particularly well suited for dose–response studies, transport phenomena research, and microenvironment control experiments.
The master mold is optimized for soft lithography workflows, supporting repeatable PDMS casting with consistent channel geometry. Its large-format layout allows researchers to study gradient behavior over extended distances while maintaining fine control over flow conditions.
This product is intended for academic laboratories, industrial R&D teams, and early-stage technology developers evaluating gradient-based microfluidic systems prior to custom device development or scale-up.

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.
