An article of laboratory glassware for directing the flow of chemical materials is described. The article includes a glass manifold having a plurality of input ports and at least one output port, and a plurality of stopcocks. Each stopcock has an inlet port and an outlet port connected by a passageway through the plug. Each of the stopcock output ports is connected to one of the manifold input ports, and each stopcock input port is connected with one end of a hollow glass tube, and the other end of the hollow glass tube is connected to a ground glass joint. The output ports of the manifold are terminated to a ground glass joint. Each plug is rotationally coupled to a planetary gear arrangement operated by a stepper or electrical motor, and rotational position can be sensed by a sensor. The rotation of each rotating plug is controlled by a computer.

There is provided a method and materials pertaining to assays, for example immunoassays, for biomarkers in body fluids e.g. blood. Diagnostic or screening methods for infections, and methods of differentiating between infectious and non-infectious conditions in mammals, particularly equines, for monitoring response to anti-infective/antibiotic therapy are provided. A test fluid collection system adapted to permit dilution and analysis of the collected test fluid and an assay and device for monitoring exertional rhabdomyolysis in equines is also provided.

A probe assembly for aspirating and delivering liquids includes a liquid line having a liquid line end and a pipette configured to be in fluid communication with the liquid line, the pipette configured to aspirate and dispense liquids when the probe assembly is devoid of connections to external liquid sources other than liquids being aspirated or dispensed, the liquid line end having a first portion of a dynamic coupler configured to be dynamically coupled to a second portion of a dynamic coupler, and the second portion of the dynamic coupler configured to be in fluid communication with a liquid source external to the probe assembly. Other probe assemblies, testing apparatus, and methods are disclosed.

A digital burette comprising a housing configured to be mounted on a liquid reservoir, a tube extending from the housing, an input unit provided on the housing, and an actuating device/unit/component/machine/structure configured to communicate with the control unit. The tube fluidly communicates with the liquid reservoir. The input unit receives an input corresponding with a desired volume of the liquid to be dispensed, and generates an input signal. The control unit receives the input signal and generates a processed signal. The actuating device/unit/component/machine/structure is communicatively coupled to the input unit or the control unit to facilitate dispensation of the desired volume of the liquid through the tube based on the received input signal/processed signal.
