Abstract
The utility model discloses multi-functional convenient pipette belongs to the application of glass instrument manufacturing technique, because the pipette has a plurality of tripes, and similar medical syringe formula suction means can be connected at the top, therefore a pipette can move the liquid of getting multiple volume, and convenient rapid, easily washs.
Description
The utility model belongs to chemical analysis instrument.
Pipette such as Fig. 1 commonly used at present, the process that it pipettes liquid is as follows; The sharp mouth of ear washing bulb (seeing accompanying drawing 2) to living the pipette mouth of pipe, is extruded air in the ball, and finger comes up then, makes solution slowly in the suction line, because of the ear washing bulb capacity limited, so often need absorption repeatedly repeatedly.When solution suction scaleover graticule is above, remove ear washing bulb, right hand forefinger is pinned the mouth of pipe immediately, and pipette is proposed liquid level, make pipe end lean against the volumetric flask wall, loosen finger then slightly, liquid in pipe oozed, when the solution concave meniscus just and graticule when tangent, press the tight mouth of pipe with forefinger immediately, liquid is no longer flowed out, take out pipette, move in the container of preparing to accept.At actual no calibration pipette commonly used when measuring the liquid of a certain amount of volume, because of pipetting the needs that liquid has multiple volume often in the experiment, thereby need frequent replacing pipette.In addition, ear washing bulb also has the branch of size, and Qi Jianzui has thickness not, and when using the pipette of different size, normal thickness because of pipette needs frequently to change ear washing bulb and causes many troubles.
The purpose of this utility model is in order to overcome the defective that above-mentioned common pipette exists, to provide a kind of and can pipette multiple volume solution and convenient novel rapidly pipette.
What the utility model used is the manufacturing technology of glass apparatus, accompanying drawing 1 is common pipette, and wherein 1 is the pipe tripe that storaging liquid is used, the 2nd, and the scale graticule, indicate that this scale just reaches the volume that defined pipettes liquid, Fig. 2 is the ear washing bulb that imbitition is used.In accompanying drawing 3,1,2,3 all is the pipe tripe of storing solution body and function, and each pipe tripe top all has to the degree line, from the top down, each graduation mark all corresponding the solution of certain volume.As required, the quantity of pipe tripe can also increase or reduce again.For imbitition more easily, also the syringe type liquid sucking device can be set.Accompanying drawing 4 is that Fig. 3 was made some improved pipettes, its difference is pipette suitable for readingly becomes taper, Fig. 5 is a liquid sucking device, compare with injector for medical purpose (accompanying drawing 6), its following suction inlet was also done the improvement of taper as shown of some shapes, this is more closely to combine with the pipette mouth of pipe in order to make it, and accompanying drawing 7 is of the present utility model moulded.
The utility model is owing to have a plurality of pipe tripes on the pipe shaft, thereby pipette just can realize pipetting the needs of multiple volume of liquid, avoided the trouble of frequent replacing pipette, traditional calibration pipette (seeing accompanying drawing 8) only is fit to measure the liquid of smaller size smaller though can realize that also a pipe pipettes the needs of multiple volume of liquid, otherwise, it is big more to measure liquid volume, because of pipe range can not extend arbitrarily, then caliber is thick more, and error is big more.
In addition, because the utility model has also adopted the syringe type liquid sucking device, thereby imbibition is comparatively rapidly convenient.
Claims (3)
- (1) a kind of chemical apparatuses that liquid is used---pipette that pipettes is characterized in that having on the pipe shaft pipe tripe of a plurality of deposit liquid.
- (2), it is characterized in that all there is a graduation mark each pipe tripe top according to the pipette of claim (1).
- (3) according to the pipette of claim (1), on the mouth of pipe, can connect similar medical syringe type liquid sucking device.
