PDMS commonly known as silicone is used to fabricate microfluidic devices. In the lab, a mixing machine is used to combine the two reagents bottles to form silicone without bubbles that cures in the oven. In soft lithography, the PDMS is poured on microfabricated channels, heated, and then peeled off the structures to make a device against a glass surface. More complex devices use a series of thin layers of PDMS to incorporate microfluidic valves. The spin coater is used to control the thickness of the membrane between layers forming the valves in multilayer soft lithography.
