[0040] (1) The multi-port sampling valve (12) (22) is switched to the channel of the diluent container, and each channel is opened in turn, so that the whole system is filled with the diluent;

[0041] (2) The multi-port sampling valve (12) (22) is switched to the probe channel, the sample rotating disk (31) (41) rotates to the first sample position, the probe (1) moves down into the test tube, and the scheduling control The device (5) selects the micro-sampler (assumed to be 14) involved in the work according to the amount of liquid set by the method, the three-way or multi-way sampling valve (17) is switched to the waste liquid bucket channel, and the micro-sampler (14) moves , fill the channel with sample solution;

[0042] (3) The three-way or multi-way sampling valve (17) is switched to the channel (19), and the piston of the micro-sampler (14) moves upward to distribute the quantitative sample liquid to the corresponding container of the sample rotating disk (41);

Abstract

The invention relates to a full-automatic diluting instrument which can absorb a diluent automatically from a diluent channel, suck samples from a sample rotating disc one by one as a mother liquid, and injects and mixes the diluted liquids into corresponding tubes successively, thereby completing automatic diluting function of large-scale liquids. A system comprises dual-channel probes, multi-way injection valves, three-way valves, three-way or multi-way sample-separating valves, micro injectors, injector drive arms, probe drive arms, sample rotating disks, rotating disk bearings, rotating motors, a diluent container, a gas container, a waste liquid barrel, corresponding gas or liquid channels, a scheduling controller and a synchronous controller. The full-automatic diluting instrument performs sampling work by synchronously rotating the sample disk and through the movement of the probes, achieves a large-scale diluting object by combining up and down movement of the micro injectors and open and close of various valves, and can be widely applied in chemistry, biotechnology or other analytical testing experiments.

Description

technical field [0001] The invention relates to an automatic instrument capable of diluting a large batch of chemical or biological liquid samples one by one, which is precisely scheduled and synchronized by a combination of a sample rotating disk, a micro-injector and a valve. Background technique [0002] In chemical and biological analysis and testing experiments, large quantities of high-precision liquid dilution are often required. In addition to the traditional manual use of pipettes and pipette guns, some high-end customers also use xyz dilution workstations. The so-called dilution workstation is a system that automatically dilutes with a manipulator. The manipulator can accurately pipette from left to right or in the opposite direction, and the pipetting head sucks and distributes samples through the XYZ axis. Due to the mechanical arm, this method has complex structure, high cost and complicated maintenance, so many customers find it difficult to accept it. The pur...
