A plate handling device includes a base having a first and second base member configured to hold a plate. The base is adapted to expand and contract to secure the plate to the plate handling device. The plate handling device includes a handle having an upper end and a lower end, and the handle is adapted to actuate the expanding and contracting of the base to secure and hold the plate. An outer handle member is fixedly attached to the first base member. A user interface member is fixedly attached to the second base member, is pivotably attached to the lower end of the handle, and is pivotably receivable in portions of the outer handle member.

Plate handling devices and methods for plate handling of analytical and culture vessels

A system for processing biological or other samples includes an array of transducer elements that are positioned to align with sample wells in a microplate. Each transducer element produces ultrasound energy that is focused towards a well of the microplate with sufficient acoustic pressure to cause inertial cavitation. In one embodiment, the transducers are configured to direct ultrasound energy into cylindrical wells. In other embodiments, the transducer elements are configured to direct ultrasound energy into non-cylindrical wells of a microplate.

Ultrasound system for shearing cellular material

Disclosed embodiments include illustrative piezoelectric element array assemblies, methods of fabricating a piezoelectric element array assembly, and systems and methods for shearing cellular material. Given by way of non-limiting example, an illustrative piezoelectric element array assembly includes at least one piezoelectric element configured to produce ultrasound energy responsive to amplified driving pulses. A lens layer is bonded to the at least one piezoelectric element. The lens layer has a plurality of lenses formed therein that are configured to focus ultrasound energy created by single ones of the at least one piezoelectric element into a plurality of wells of a microplate disposable in ultrasonic communication with the lens layer, wherein more than one of the plurality of lenses overlie single ones of the at least one piezoelectric element.

A double and triple barrel electrode for the simultaneous measurement of pH and P.sub.CO2 ; and pH, P.sub.CO2 and P.sub.02 employing a membrane in conjunction with a pH fluid and fluids responsive to CO.sub.2 and O.sub.2. The responsive fluids exhibit a pH change upon a change in the concentration of the particular analyte in the responsive fluid. The liquid membrane is selectively permeable to H.sup.+ ion, and permeable to CO.sub.2 and O.sub.2 gas.
