An ultrasonic sonication device includes a velocity transformer or probe which, when coupled to a vibrating transducer of the piezoelectric or magnetostrictive type, resonates in sympathy with the transducer and either increases or decreases the magnitude of the transducer's vibration. A shallow cup assembly is attached to the distal end of the probe. The cup assembly holds a microtiter tray in a suitable orientation and contains an amount of liquid which provides efficient acoustic coupling between a transverse end face of the probe and the microtiter tray.       Recently Added Patents Constellation of chambers for distributing pneumatic pressure Dual stage cyclone vacuum cleaner Time-domain gated filter for RF communication systems Method and apparatus for preventing illegal reuse of digital right management content in portable terminal Multi-purpose crossbow cocking device and method Dental adhesive compositions and methods Quantum cascade laser suitable for portable applications   Randomly Featured Patents Method of manufacturing a semiconductor device Method and apparatus for inspecting the barrel of a firearm Regenerative jammer with multiple jamming algorithms Stiffness detector, stiffness detection method, and paper sheet processor including stiffness detector Integrated-optic, polarization-selective phase modulator Zea mays seeds and plants with reduced expression of the ACS2 gene Composition for preventing unwanted oxidation of redox indicators System for the reduction of laser equivalent surface and for optical protection Liquid droplet ejecting apparatus, liquid droplet ejecting system, electro-optical device, method of manufacturing electro-optical device, method of forming a metal wiring line, and electronic Vehicle driveshaft © 2006-2008 PatentGenius.
