Specific embodiment
Below by specific embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of multichannel pipettor provided by the utility model, it includes suction pipe 1 and suction nozzle 3.
Piston 11 is equipped in the suction pipe 1, the push-and-pull end of the piston 11 is located at wherein one end of the suction pipe 1；?
The other end of the suction pipe 1 is equipped with the first sealing-plug 9, is equipped on first sealing-plug 9 several through first sealing
Plug 9 and the first pipe connector 6 for outwardly extending one end distance.
Wherein one end of suction nozzle 3 is equipped with the second sealing-plug 10, is equipped on second sealing-plug 10 and runs through described second
Sealing-plug 10 and the second pipe connector 12 for outwardly extending one end distance；And the other end of the suction nozzle 3 is liquid taking port,
Liquid outlet, be it is easy to use, be set to closing in type port.
First pipe connector 6 and second pipe connector 12 are connected by connecting tube 5.
A kind of multichannel pipettor provided by the utility model further includes a suction nozzle mounting bracket 2, the suction nozzle installation
