When it comes to the production of low cost, high volume disposables, polymer is your material of choice. It is also the most used material for fast prototyping or short production runs. Fabrication techniques for polymer microfluidic devices are relatively simple, compared to those of glass and silicon.
There are many types of polymer available that allow tuning of material properties, which makes polymer an excellent medium for microfluidic applications. It’s especially useful in many biological, pharmaceutical, and medical applications due to its biocompatibility and optical transparency. Polymers are also used as an extension to the predominantly silicon basis of MEMS.
Working with polymers can also be useful when a scale-up in production volumes is expected. When this is taken into account at the initial stage of the process, a relatively smooth technology transfer to another polymer can be realized. This way, costs, lead times, and functionality remain manageable.
At Micronit, the most commonly used polymers are PMMA, PS, COC, and PC.
