The chip is composed of a glass microfluidic component and a plastic interface (PEEK) forming the wells and the recording chamber. The plastic interface has been treated with titanium first, then with silicon oxide to allow for even wetting. The bottom of the chip is made of hard anodised aluminium. The lid is made from polycarbonate, O rings and seals from Viton and tubing in Teflon. We are using material that is standard for biological applications.
