  • Publication number: 20250144625
    Abstract: According to the disclosure, a cartridge for detecting a target analyte, comprising: a base, a sample chamber, a first mixing chamber accommodating a magnetic bead, a second mixing chamber accommodating a dry reagent, a shuttle chamber for dissolving the dry reagent of the second mixing chamber, and a detection chamber for detecting the target analyte. The shuttle chamber is configured to dissolve the dry reagent in a sample solution provided from the first mixing chamber. The fluid in the second mixing chamber is moved to the shuttle chamber by positive pressure provided from the first pneumatic port, or the fluid in the shuttle chamber is moved to the second mixing chamber by negative pressure provided from the first pneumatic port.

  • Publication number: 20240139738
    Abstract: According to the disclosure, a target analyte detection cartridge includes a sample chamber into which sample is inserted, a metering chamber connected to the sample chamber to meter a predetermined amount of sample, a mixing chamber connected to the metering chamber to receive a magnet bead, and a waste chamber connected to the metering chamber. The metering chamber has one side connected to each of the sample chamber and the mixing chamber and another side connected to the waste chamber. A first pneumatic flow path to which pneumatic pressure is provided is connected to a waste flow path that joins the other side of the metering chamber to connect the metering chamber and the waster chamber.

  • Patent number: 6507141
    Abstract: Vibratory tuning fork having a body of piezoelectric material with a base and a pair of tapered tines which extend from the base and decrease in lateral dimension from the base toward the tips of the tines. A crotch section at the base of the tines has an inner pair of faces which lie in crystallographic planes of the piezoelectric material and an outer pair of faces which lie in additional crystallographic planes of the material and extend between the inner pair of faces and the tines. An isolation slot is formed in the base adjacent to the crotch, with enlarged cut-outs at the ends of the slot to prevent the formation of facets and membranes across the slot.
