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.

Abstract: Tuning fork and method in which a pair of elongated tines having front and rear surfaces are disposed symmetrically about an axis, and balancing masses on the front surface of one tine and on the rear surface of the other tine are trimmed to reduce quadrature error and also to maintain mass balance between the tines.

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.
