摘要： The present invention discloses a liquid volumetric device comprising a metering tube, a start sensor, an end sensor, a bath for storage of a sample to be metered, a vacuum chamber and a pump for pumping out air inside the vacuum chamber to form a negative pressure inside the vacuum chamber. The start sensor and the end sensor are provided respectively at the bottom and the top of the metering tube, the top of the metering tube is in communication respectively with the vacuum chamber and the outside atmosphere via pipelines, the bottom of the metering tube is in communication respectively with the bath and the vacuum chamber via pipelines, and control parts are provided in each of the pipelines for controlling connection/disconnection thereof. Thus, by forming a negative pressure inside the vacuum chamber, a sample in the bath may be pressed from down to up into the metering tube by means of a pressure difference between the atmosphere and the negative pressure, so as to complete the volume metering, whereby an occurrence of the side flow phenomenon can be completely eliminated.

摘要： A device and a method for distributing measurement sample and cleaning tubes, wherein the device comprises: a diluent container for accommodating a diluent therein; an aspirating tube for sucking a measurement sample; a first syringe driven by a power unit and used to quantify the measurement sample; a second syringe driven by the power unit and used to quantify the diluent; a first switching unit connected to the first syringe, the second syringe and the diluent container, for switching between a communication of the second syringe with the diluent container and a communication of the second syringe with the first syringe; a bath; a sample buffer tube communicated with the first syringe at a port thereof; a dispensing tube for dispensing the measurement sample and/or the diluent into the bath; a second switching unit connected to an output port of the aspirating tube, the other port of the sample buffer tube and an input port of the dispensing tube, for switching between a communication of the other port of the sample buffer tube with the input port of the dispensing tube and a communication of the other port of the sample buffer tube with the output port of the aspirating tube. A reagent buffer tube, a reagent container and a third switching unit may be further provided between the sample buffer tube and the first syringe, or between the second switching unit and the input port of the dispensing tube. With said method and device for distributing measurement sample and cleaning tubes according to the present invention, the fluidic system and mechanical construction are simplified, and thus the cost of manufacture is reduced, the control complexity is lowered.
