3M Microfluidic Hydrophilic Film 9984, Surfactant Free
A surfactant free hydrophilic polyester film used in microfluidic diagnostic devices, including test strips and lab on a chip applications.
The Medical Diagnostic Microfluidic Hydrophilic Film, catalog number 9984, is a specialised film used in the manufacture of health care medical devices that rely on microfluidic technology, such as test strips and lab on a chip applications. It consists of a clear polyester film supplied on a roll, coated on one side with a hydrophilic treatment that is surfactant free, meaning the hydrophilic property is built into the coating without relying on a surfactant that could otherwise leach out and potentially interfere with a diagnostic assay.
This hydrophilic surface helps control how fluid moves and spreads within a microfluidic device, which is important for accurate sample handling in diagnostic testing. The listing notes this product is transitioning to the equivalent Solventum branded Microfluidic diagnostic film, 9984, part of the ongoing rebrand of former 3M diagnostic products rather than a change to the material itself.
This film is intended for use by diagnostic device manufacturers during production rather than for direct clinical application, and distributors keep it stocked to support ongoing microfluidic device manufacturing.
