Abstract: One or more techniques and/or systems are disclosed for a universal-type pump casing that allows for coupling to various piping couplers, for various sizes of fluid lines. This can allow the pump casing to accept the majority of current fluid line coupling, for various fluid line sizes used with these types of pumps, thereby eliminating the need to have a different casing for each different sized fluid line. A universal-type pump casing with a proximal end engaged with a pump bracket, and a distal end affixed to an end plate to define the pumping chamber. A first and second port can have an opening of a predetermined diameter, with a port face that can couple with various modular port flanges, to provide different port flange configurations.

Abstract: A biological material sensing surface is exposed to a biological material that is selectively bound to a selected sensing portion of the sensing surface. The sensing surface is then subjected to shear stress oscillations to selectively remove nonspecifically bound material. The shear stress may be provided by an ultrasound resonator operating at a power sufficient to selectively remove nonspecifically bound biological material, such as protein from non-sensing areas of the sensing surface, which may be micropatterned array.
