Abstract

The utility model relates to a liquid moving device which comprises a liquid moving cylinder, a suction head arranged at the lower end of the liquid moving cylinder, a volume adjusting button arranged at the upper end of the liquid moving cylinder and a digital display screen arranged on the liquid moving cylinder. The liquid moving device also comprises a filtering device, wherein one end of the filtering device is fixedly connected with the liquid moving cylinder, and the other end of the filtering device is connected with the suction head in a detachable way; the suction head is in tapered plug-type detachable connection with the filtering device. The liquid moving device has the beneficial effects that the filtering device is arranged between the suction head and the liquid moving cylinder, so that impurities do not easily exist in the liquid moving cylinder, and the liquid moving device is safe and convenient to use; the detachable suction head of the liquid moving device can be matched with the liquid moving device for use according to the different size specifications; furthermore, when different liquids are moved and taken, the suction head of the liquid moving device is replaced without being cleaned, so that the liquid moving device is simple and convenient, and the cross contamination among the different liquids can be effectively avoided.

Description

A kind of pipettor

Technical field

The utility model relates to a kind of pipettor.

Background technology

Pipettor is of a great variety, generally parts such as moving fluid cylinder and suction nozzle, consist of, but existing pipettor cylindrical shell easily precipitates some pollution impurity, if different samples easily produces and pollutes after suck-back through repeatedly using.Further being improved on this basis, be transformed into the suction nozzle with filter core by suction nozzle, but high expensive like this.

The utility model content

The utility model is for above-mentioned the deficiencies in the prior art, and a kind of safe and convenient to use, pipettor that cost is low is provided.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of pipettor, comprise and move fluid cylinder, be positioned at the suction nozzle that moves the fluid cylinder lower end, be positioned at the tune amount button that moves the fluid cylinder upper end and be located at the digital display screen moved on fluid cylinder, it is characterized in that, also comprise filter, an end of described filter with describedly move that fluid cylinder is fixedly connected with, the other end and described suction nozzle removably connect.

On the basis of technique scheme, the utility model can also be done following improvement.

Further, described suction nozzle and described filter are that the conical plug formula removably connects.

The beneficial effects of the utility model are: at suction nozzle with move between fluid cylinder and be provided with filter, make to move in fluid cylinder to be difficult for existing impurity, and safe and convenient to use; Dismountable suction pipette head, can support the use according to different size specifications, and, when pipetting different liquids, change suction pipette head and get final product, without cleaning, simple and convenient, avoids the mutual pollution between different liquids.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

The A section structure amplification profile schematic diagram that Fig. 2 is Fig. 1.

Digital display screen in the drawings, 1, move fluid cylinder, 2, suction nozzle, 3, filter, 4, tune amount button, 5.

The specific embodiment

Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

As depicted in figs. 1 and 2, a kind of pipettor, comprise and move fluid cylinder 1, be positioned at the suction nozzle 2 that moves fluid cylinder 1 lower end, be positioned at the tune amount button 4 that moves fluid cylinder 1 upper end and be located at the digital display screen 5 moved on fluid cylinder 1, tune amount button 4 is connected with described digital display screen 5 with batcher by being positioned at the tune gauge rod that moves fluid cylinder 1, this pipettor 1 also comprises filter 3, an end of described filter 3 with move that fluid cylinder 1 is fixedly connected with, the other end and suction nozzle 2 removably connect.

Described suction nozzle 2 removably connects for the conical plug formula with described filter 3.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.

Claims
