Abstract
A kind of graduated pipette, relates to a kind of instrument for chemical experiment.It solve pipette in prior art move liquid measure be quantitatively, deficiency that experimental implementation is more loaded down with trivial details, solve the problem of the easy landing of ear washing bulb imbibition.A kind of graduated pipette, comprise pipette body and Jian Zui, it is characterized in that: the top of described pipette body is with conical pipette mouth, conical pipette mouth opening part aperture is greater than the aperture of pipette body, pipette body outer surface is provided with scale, pipette body medium design has liquid storage pipe, and pipette body is provided with piston switch.The utility model, by arranging pipette tip in horn-like, is convenient to ear washing bulb imbibition.Middle piston-type switch is conducive to controlling the liquid level in body, makes it be not easy outflow.
Description
Technical field
The utility model belongs to experiment equipment field, is specifically related to a kind of pipette.
Background technology
Pipette is a kind of equipment measuring liquid comparatively accurately.When laboratory is tested, often pipette solution with the disposable pipette that specification is 10ml, 25m, 50ml, the volume pipetted is different, and selected pipette is also different, and when measuring 15ml, 20ml equal-volume, also need two pipettes even three pipettes with the use of, bring inconvenience to experimentation, the disposable pipette of 50ml such as, only have a graticule, expression be volume size be 50ml, moving liquid must quantitatively, make experimental implementation more complicated at every turn.When using the pipette of this specification, because its top is very little, when using ear washing bulb imbibition, being not easy the hole aiming at pipette, operating very inconvenient.At present, most of pipette is all block the suitable for reading of pipette with finger after imbibition, because finger blocks the imprecision of the mouth of pipe, causes liquid level easily to decline.
Summary of the invention
The utility model object is to provide a kind of pipette, solves too little being not easy in existing pipette aperture and uses ear washing bulb imbibition problem.Namely moving liquid measure for pipette in prior art is the deficiency quantitative, experimental implementation is more loaded down with trivial details, provides a kind of graduated pipette.The decline that piston-type switch solves liquid level when existing pipette moves liquid is set.
A kind of graduated pipette, comprise pipette body and Jian Zui, it is characterized in that: the top of described pipette body is with conical pipette mouth, conical pipette mouth opening part aperture is greater than the aperture of pipette body, pipette body outer surface is provided with scale, pipette body medium design has liquid storage pipe, and pipette body is provided with piston switch.
According to described graduated pipette, the capacity of described pipette body is 50ml.
The utility model compared with prior art tool has the following advantages: the utility model, by arranging pipette tip in horn-like, is convenient to ear washing bulb imbibition.Middle with piston-type switch, be easy to the liquid level in control valve.Replace the disposable pipette of all size, easy to use, avoid the trouble repeatedly using pipette.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In accompanying drawing: 1, pipette body; 2, conical pipette mouth; 3, liquid storage pipe; 4, piston switch; 5, Jian Zui; 6, graduation mark.
Detailed description of the invention
A kind of pipette, comprise pipette body 1 and sharp mouth 5, the top of pipette body 1 is conical structure, the aperture of opening part cross section is greater than the aperture of other partial cross sectional, middle for being designed with body and the piston switch 4 of liquid storage pipe 3, lower end is provided with sharp mouth 5, and described outer surface of tube body is evenly equipped with graduation mark 6.
For ease of display piston structure, in accompanying drawing, piston switch 4 is separated with pipette body 1.
As shown in Figure 1, pipette comprises the liquid storage pipe 3 that centre is provided with piston mouth, and the top of described pipette body 1 is conical structure, forms bell mouth shape, is convenient to ear washing bulb imbibition.Described pipette body 1 lower end is provided with sharp mouth 5, and outer surface is evenly equipped with graduation mark 6.Middle piston-type switch is easy to the liquid level in control valve.The utility model replaces the disposable pipette of all size, easy to use, avoids the trouble repeatedly using pipette.
The utility model is when making, and the capacity of described body is 50ml.
The above embodiment only have expressed the detailed description of the invention of the application, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the application's protection domain.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from technical scheme design, can also make some distortion and improvement, these all belong to the protection domain of the application.
Claims (2)
1. a graduated pipette, comprise pipette body (1) He Jianzui (5), it is characterized in that: the top of described pipette body (1) is with conical pipette mouth (2), conical pipette mouth (2) opening part aperture is greater than the aperture of pipette body (1), pipette body (1) outer surface is provided with scale (6), pipette body (1) medium design has liquid storage pipe (3), pipette body (1) is provided with piston switch (4).
