Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
In following embodiment and embodiment: the manufacturer of multiple valve is: Switzerland Ha Meidun Beaune Tu Si joint-stock company, wherein the model of eight channel valve is VALVE, CERAMIC, HVCX8-5; Multiple valve can rotate by the angle of spool, realizes the connection of different liquid delivery port and liquid pumping needle connector.The manufacturer of liquid pumping needle is: Switzerland Ha Meidun Beaune Tu Si joint-stock company, model is 1005.5TLL SYR30MM.
As shown in Figure 1, be dosing and the liquid distributing device schematic diagram of a kind of embodiment of the utility model.Be used for the reagent of mix reagent bottle 11 and dye liquor is delivered to sample to be dyed, in a kind of embodiment of the utility model, sample to be dyed is placed on microslide 13, and microslide 13 is positioned on microslide pallet 12.Dosing of the present utility model and liquid distributing device comprise:
In a kind of embodiment of the utility model, multiple valve 6 is VALVE, CERAMIC, and HVCX8-5, it is provided with 8 liquid delivery ports; 6 liquid delivery ports are communicated with reagent bottle 11 by catheter 10; 2 liquid delivery ports are delivered to sample to be dyed by catheter 10 by dye liquor.Concrete connected mode, for pipe adapter 7 is screwed in the box thread of liquid delivery port, realizes multiple valve 6 and is communicated with reagent bottle 11
