Lattice take liquid rifle to support the use different size of pipette tips, take liquid rifle to belong to precision instrument, use and are intended to careful when depositing, prevent
Stop loss bad, it is to avoid influence its range.When adjusting range, if to be adjusted to small size from large volume, according to normal regulation
Method, rotate counterclockwise knob；But if to be adjusted to large volume from small size, then can first turn clockwise dialing knob
To the scale more than range, then setting volume is pulled back to, can so ensure the highest accuracy measured.Button is first pressed to
Two rest points, the button that comes up is to origin, after sucting, and leans to chamber wall and surplus liquid is flowed back into container along wall.Take
Liquid rifle is the common tool in laboratory, the sampling being usually used in biological and chemical analysis or sample-adding.Taking liquid rifle, it is substantially a work
Plug suction pipe, is operated using air discharge principle, the capacity of pipettor is determined with the distance moved in piston bush.
As disclosed in China Intellectual Property Office " a kind of sampler "（Grant number：CN203443792U）, the sampler includes
First sleeve and piston, the first sleeve have first inner chamber, and upper end is provided with the first opening, and lower end is provided with the second opening,
Piston includes seal and connecting rod, and seal is fitted close with first inner chamber, and is arranged on the bottom of connecting rod, and seal can
Slided in first inner chamber, in addition to be arranged on the storage room of seal bottom.The sampler structure is simple, easy to operate, but
Temperature measurement meter and vacuum wall are the absence of, there is certain limitation in terms of test in laboratory scope.
