DEVICE FOR BIOLOGICAL LIQUIDS IMMUNOLOGICAL TESTING

摘要

This device is used widely in medicine and biology. It allows the simultaneous examination of various biological liquids under the same conditions. It consists of a plank with channels, placed in a holder above an ultrasonic transmitter, above which there is a contacting environment. A focusing ultrasonic lens, with acoustic axes, alternating at equal distances with the axes of the channels, is placed between the transmitter and the plank. The boundaries of the ultrasonic waves run close to the sides of the channels at the acoustic axes. The lens focuses the ultrasonic waves of the transmitter and behind its focal plane they are directed onto the channels.
