ABSTRACT:
A micrometering liquid sample dispenser for dispensing several sample liquids into a test tube comprises syringe samplers arranged on a stand and equal in number to the number of sample liquids, the syringe samplers being provided with pipes or hoses for conveying the metered sample liquids to the test tube, the stand being kinematically linked with a sample volume regulator. The apparatus is further provided with a control unit incorporating a sample volume and timing setter the outputs of which are connected to the sample volume regulator, to a drive for step-by-step rotation of the test tube tray and to a drive for reciprocating the ends of the sample liquid dispensing pipes. Each of the syringe samplers is provided with means for locking the piston rod thereof to effect a programmable liquid sample metering, the lock means being electrically connected with a corresponding output of the sample volume and timing setter. Also, there is a provision for a holder to hold the ends of the sample liquid dispensing pipes to dispense the sample liquid into the test tube, the holder being adapted to hydraulically communicate with the outlets of the syringe samplers via three-way valves.
