Silicon Wafers
Silicon, with its high-temperature stability, resistance to a wide range of chemicals, excellent mechanical properties and its monocrystalline structure, is a widely used material in microfluidics. The silicon wafers can be structured to a very high degree of precision through a variety of available micro and nanofabrication techniques. Silicon wafers are undoubtedly the best choice when it comes to microfluidic applications that focus on compactness, ultrafine and numerous structures. They allow the combination of microfluidics with integration and sensing and are ideally suited for use in lab-on-a-chip in the health and life sciences.
Alfa Chemistry offers a wide range of silicon wafers for multiple microfluidic applications. If you don't find the specification you need, please contact us. We can provide product customization to meet your specific requirements.
