Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description, it is clear that institute below
The embodiment of description is only the part of the embodiment of the utility model, instead of all the embodiments.Based on the utility model
Embodiment, those of ordinary skill in the art are not on the premise of creative work is made, all technologies in the utility model
Any modification, equivalent replacement, improvement and so on the basis of scheme, should be included within the scope of the utility model, all
Belong to the scope of the utility model protection.
Embodiment 1
A kind of pipette, including tube body 1, graduation mark 2 is provided with tube body 1, and the top of graduation mark 2 of tube body 1 is pushed up to tube body 1
Portion is arranged with Silicone Case 3；Several dot bulges are provided with protective case 3, annular clip is additionally provided with outside protective case 3
4, annular clip 4 is component made of corrosion-resistant material, it is anti-skidding with being provided with the inside of tube body 1 or 3 contact site of protective case
Layer, skid resistant course is silica-gel antiskid layer；The top of protective case 3 is provided with the annular convex edge 5 vertical with tube body 1, is set in annular convex edge 5
Have four ribs 6, ribs 6 is vertical with tube body 1 and two adjacent ribs 6 between be hanging hole 7；At 1 maximum scale of tube body
1 diameter of tube body be less than other pipeline section diameters.
1 lower end of pipette tube body is inserted into below liquid level during use, liquid is drawn with ear washing bulb, pinches flat ear washing bulb, then
Discharge air in ball and form pressure difference absorption liquid into pipette with ambient pressure, whole suction process keeps pipette tube body 1
, when absorption liquid is higher than graduation mark 2, ear washing bulb is taken away, press...with one's finger rapidly the mouth of pipe, passes through control under liquid level in lower end
Finger keeps hand to unclamp little by little, allows under liquid flow, dropped to until liquid level needed for untill graduation mark 2, in this when pipette
Liquid be exactly needed for volume, finger covers pipette upper end, and mobile pipette unclamps finger, liquid is just into required container
