Description
Technical Field
The utility model belongs to the technical field of laboratory appurtenance, concretely relates to take rotatory aspirator's pipette device.
Background
In medicine, drug, gene and protein research, biological research, drug development laboratories, and other biotechnology.
In the field of application, it is often necessary to remove the liquid quantitatively with a pipette. Move the pipe and often need absorb, flowing back many times in the use just can accurately find the scale position, reagent gets into the pipette and easily causes reagent pollution in arranging the reagent bottle, influences the experimental result. Through the auxiliary liquid suction device, the liquid is accurately sucked and moved at one time, and the reagent pollution is avoided.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model discloses a main aim at designs a pipette device of rotatory aspirator in area, adopts lead screw and screw hole complex mode, is suitable for multiple experiment occasion, moves the liquid volume precision high, and easy operation adopts the filter plug to effectively reduce reagent pollution probability, reduces misoperation phenomenon.
In order to realize the purpose, the utility model adopts the following technical scheme:
a pipette device with a rotary aspirator comprises a pipette, a filter plug and a rotating rod device.
The rotating rod device comprises a rotating rod cylinder, a screw hole is formed in the upper portion of the rotating rod cylinder, a lead screw is arranged in a matched screw hole, a piston is arranged at the bottom of the lead screw and closely matched with the inner wall of the rotating rod cylinder, the upper portion of the filter plug is connected with the bottom of the rotating rod cylinder, the lower portion of the filter plug is connected with a pipette, and scales are arranged on the pipette.
As the utility model discloses further description, the filter plug all set up a screw section of thick bamboo from top to bottom, swing arm bobbin base portion and pipette upper portion set up the internal thread, both ends link to each other with a swing arm section of thick bamboo and pipette through threaded connection's mode respectively about the filter plug.
As a further description of the present invention, the filter plug is self-sealing microporous filter.
As a further description of the present invention, the scale is provided below the filter plug.
Compared with the prior art, the utility model discloses a technological effect does:
the utility model provides a pipette device with a rotary liquid sucker, which adopts a mode that a screw rod is matched with a screw hole, is suitable for various experimental occasions, has high liquid-transferring amount precision and simple operation;
the device adopts the filter stopper to effectively prevent that aerial fog from getting into rotatory lotion ware and causing reagent pollution, reduces reagent pollution probability, reduces misoperation phenomenon.
Drawings
Fig. 1 is a view of the overall structure of the present invention.
In the figure, 1 is a pipette, 11 is a scale, 2 is a filter plug, 21 is a threaded cylinder, 3 is a rotating rod cylinder, 31 is a screw hole, 4 is a screw rod, and 41 is a piston.
Detailed Description
The present invention is described in detail below with reference to the attached drawings:
a pipette device with a rotary aspirator, which is shown in figure 1, comprises a pipette 1, a filter plug 2 and a rotating rod device.
The swing arm device include a swing arm section of thick bamboo 3, 3 upper portions of a swing arm section of thick bamboo set up screw hole 31, cooperation screw hole 31 sets up lead screw 4, 4 bottoms of lead screw set up piston 41, piston 41 closely cooperates with 3 inner walls of a swing arm section of thick bamboo, rotatory lead screw 4, lead screw 4 drives piston 41 and removes, 2 upper portions of filter plug connect 3 bottoms of a swing arm section of thick bamboo, filter plug 2 sub-unit connection pipettes 1, set up scale 11 on the pipette 1, store liquid in the pipette 1.
All set up screw cylinder 21 about filtering plug 2, swing arm bobbin base portion and pipette upper portion set up the internal thread, filter plug 2 about both ends link to each other with swing arm cylinder 3 and pipette 1 through threaded connection's mode respectively.
The filter plug 2 adopts self-sealing microporous filtration, and can effectively prevent the aerial fog from entering the rotary liquid washer to cause reagent pollution.
The scale 11 is arranged below the filter plug 2.
The utility model provides a take rotatory aspirator's pipette device adopts lead screw and screw hole complex mode, is suitable for multiple experiment occasion, moves liquid volume precision height, easy operation, reduces reagent pollution probability, reduces misoperation phenomenon.
The above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
