A cover slip mixing apparatus having a support and a flexible cover slip positioned over and forming a chamber between the support and the cover slip. A device is positioned with respect to the support and cover slip for applying a force on the cover slip and flexing the cover slip toward the support, the flexing cover slip providing a mixing action of a material located in the chamber. A microfluidic device includes a substrate with a fluid path disposed in the substrate. A flexible cover is positioned over the substrate and the fluid path, and a device is positioned with respect to the substrate and the cover. The device is operable to apply forces to the cover and flex the cover to act on fluid in the fluid path.
