Abstract
The invention discloses a kind of permanent magnetic piston pipette, including body, the body includes the suction end of tip and the end of tack, and the tube surfaces are provided with scale, in addition to piston and regulation ring, the piston includes main body and front portion, the main body is cylindrical, and its external diameter is adapted with the internal diameter of body, and the anterior shape is adapted with the in-profile of the suction end of body, the regulation ring is socketed on outside body, is realized and linked by permanent magnet between the regulation ring inwall and piston.The permanent magnetic piston pipette, be additionally arranged can be up and down in body piston, and control by regulation ring outside body the lifting of piston, pass through permanent magnet between the regulation ring inwall and piston and realize linkage.The pipette can be by the position of the external regulation ring of regulation pipe, without relying on the vacuum of control ear washing bulb such as Conventional pipettes, you can realize the quantitative absorption of pipette.
Description
Technical field
The present invention relates to general chemistry laboratory equipment technical field.
Background technology
One of instrument that pipette is commonly used as laboratory, existing Curve guide impeller major part focus is how to realize
Batch is drawn, or quantitative accurate absorption.Such as the Chinese patent of the patent No. 201710530667.6, disclosing one kind has electromagnetism
The batch of control draws pipette, including installing plate, slide rail, sliding block, elevating mechanism, pipette, electromagnet and corresponding liquid relief
The parts such as pipe piston.By switching whether control electromagnet is powered work, uptake is controlled by adjusting elevating mechanism, makes each shifting
Liquid pipe can draw the purpose of different liquid measures simultaneously.
The elevating mechanism of above-mentioned technical proposal is adjusted by thread spindle and wing bolt, it is difficult to determines adjustment amount
Ratio between actual uptake, it is necessary to finely tune checking, so can not play mitigation workload in actual use repeatedly
Effect.
The content of the invention
The present invention provides a kind of permanent magnetic piston pipette, and it need not coordinate ear washing bulb, and liquid level can be controlled outside body
Highly, the mode of operation of existing pipette is effectively simplified.
A kind of permanent magnetic piston pipette, including body, the body includes the suction end of tip and the end of tack, described
Tube surfaces are provided with scale, in addition to piston and regulation ring, and the piston includes main body and front portion, and the main body is cylindrical,
Its external diameter is adapted with the internal diameter of body, and the anterior shape is adapted with the in-profile of the suction end of body, the tune
Section ring set is connected to outside body, is realized and linked by permanent magnet between the regulation ring inwall and piston.
Further, the body surfaces of the piston are made up of resinae, ceramic-like, tungsten carbide class self-lubricating material.
Further, the regulation ring also includes the locating clip that can clamp body.
Permanent magnetic piston pipette disclosed by the invention, be additionally arranged can be up and down in body piston, and pass through position
In the lifting of the regulation ring control piston outside body, realized and linked by permanent magnet between the regulation ring inwall and piston.Should
Pipette can be by the position of the external regulation ring of regulation pipe, without relying on the vacuum of control ear washing bulb such as Conventional pipettes
Degree, you can realize the quantitative absorption of pipette.
Brief description of the drawings

All connection/annexations, not singly refer to component and directly connect, and refer to be added deduct by adding according to specific implementation situation
Few couple auxiliary, to form more excellent draw bail.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Embodiment 1：As shown in figure 1, a kind of permanent magnetic piston pipette, including body 1, piston 2 and regulation ring 3, the pipe
The suction end 11 of body 1 including tip and the end 12 of tack, the surface of body 1 are provided with scale, the piston 2 include main body with
Front portion, the main body is cylindrical, and its external diameter is adapted with the internal diameter of body 1, the anterior shape and the suction end of body 1
11 in-profile is adapted, and the regulation ring 3 is socketed on outside body 1, by forever between the inwall of regulation ring 3 and piston 2
Magnet realizes linkage.The body surfaces of the piston 2 are made up of resinae, ceramic-like, tungsten carbide class self-lubricating material.The tune
Section ring 3 also includes the locating clip that can clamp body 1.
The better embodiment of the present invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make a variety of equivalent modifications on the premise of without prejudice to spirit of the invention or replace
Change, these equivalent modifications or replacement are all contained in the application claim limited range.
