Abstract
The utility model discloses a kind of pipette, comprise body, graticule mesh, ball float and block lobe.This body is the slender glass tube that middle part is expanded, and this graticule mesh is fixed in the slender glass tube of upper end, is positioned at and blocks lobe lower end, and this obstruction lobe is horn-like for being inverted, and upper end is provided with opening, lower end and body seamless link, and this ball float is in graticule mesh and block between lobe.The utility model advantage: structure is simple, and easy to operate, precision is high, and cost is low.
Description
Technical field
The utility model relates to a kind of chemical experiment measuring instrument, particularly relates to a kind of pipette.
Background technology
In chemical experiment normal need to use quantitatively measure, pipetting, the instrument that existing laboratory is commonly used mainly contains graduated cylinder and common pipette, but there is following shortcoming: graduated cylinder cylindrical shell graduation mark is dense, the larger accuracy of artificial recognition error is lower, moreover, needs in the end to use glue head dropper to add a little liquid when graduated cylinder measures designated volume liquid, to guarantee that liquid reaches graduation mark, and being no more than graduation mark, not only process complexity is loaded down with trivial details for it, and may add and too much cause measuring unsuccessfully; Although common pipette accuracy is higher, but with the device such as ear washing bulb or liquid-transfering gun with the use of time, liquid volume is made to reach pipette graduation mark by imbibition and tapping, imbibition and the more difficult assurance of tapping operation, very easily occur inhaling many or put many after need the problem that repeats, quantitative liquid getting process is higher to operator's technical requirement.For overcoming above-mentioned technical deficiency, need the liquid-transfering device designing a kind of not only practicality and high efficiency but also can ensure to measure precision.
Utility model content
Content of the present utility model is to overcome the deficiencies in the prior art, provides a kind of simple to operate, accuracy is high, structure is simple, cheap for manufacturing cost accurate liquid-transfering device.
The utility model is achieved through the following technical solutions: a kind of pipette, comprises body, graticule mesh, ball float and blocks lobe.Body is similar to Conventional pipettes, for there is the slender glass tube of enlargement at middle part, this graticule mesh is fixed in the slender glass tube of upper end, be positioned at and block appropriate location under lobe, liquid can be allowed to pass through, this ball float is be positioned at the very little bead of graticule mesh upper density, when sucking liquid in body, ball float can be floating along with liquid level, this obstruction lobe is positioned at graticule mesh top, be that an inversion is horn-like, block lobe upper end and have certain opening for air flowing, lower end and body seamless link, when after adding liquid in body, liquid level rises to graticule mesh and continues to rise, ball float can rise together along with liquid level and the lobe that finally gets clogged blocks, liquid level will stop rising, in body, liquid is just specified amount.
As the preferred embodiment of technique scheme, this cell material does not react with solution, for ball float is limited to FX.
As the preferred embodiment of technique scheme, this ball float material does not react with solution, and floating ball diameter is between obstruction lobe osculum and large mouth.
As the preferred embodiment of technique scheme, this obstruction lobe material does not react with solution, and blocking lobe is that an inversion is horn-like
The utility model has the following advantages compared to existing technology: a kind of pipette that the utility model provides, and is applicable to the quantitative pipetting processes such as laboratory.Can with ear washing bulb or the quick imbitition of liquid-transfering gun when quantitatively measuring liquid, can block with the ball float lobe until ball float gets clogged that rises together when liquid levels arrives ball float, liquid level stops rising, and in body, liquid reaches specified amount simultaneously, does not need manual adjustment again.Ball float is less with obstruction lobe place pipe diameter, can put forward the precision ensureing to get liquid volume.The utility model does not need auxiliary equipment, efficiently can move liquid fast, reaches designated volume and automatically stops, and avoids and repeats to inhale the step of putting.The utility model structure is simple, and easy to operate, precision is high, and cost is low, is applicable to promote the use of on a large scale.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
See Fig. 1, the pipette of a kind of improvement provided of the present utility model, comprises body 1, graticule mesh 2, ball float 3 and blocks lobe 4.Body 1 is similar to Conventional pipettes, for there is the slender glass tube of enlargement at middle part.Graticule mesh 2 is fixed in the slender glass tube of upper end, is positioned at and blocks lobe 4 times appropriate locations, liquid can be allowed to pass through.Ball float 3 is for being positioned at the very little bead of graticule mesh 2 upper density, and when sucking liquid in body 1, ball float 3 can be floating along with liquid level.Block lobe 4 and be positioned at graticule mesh 2 top, be that an inversion is horn-like, block lobe 4 upper end and have certain opening for air flowing, lower end and body seamless link, when after adding liquid in body 1, liquid level rises to graticule mesh 2 and continues to rise, ball float 3 can rise together along with liquid level and the lobe 4 that finally gets clogged blocks, and liquid level will stop rising, and in body, liquid is just specified amount.The utility model advantage: structure is simple, and easy to operate, precision is high, and cost is low.Pipette each several part all uses the glass or other materials that do not react with solution.
The accurate pipette that the utility model provides can be made into not co-content specification, first corresponding model is chosen according to measuring liquid volume in use, aim at this pipette tip with the device such as ear washing bulb or liquid-transfering gun and draw testing liquid, when liquid rises to graticule mesh place and continues to rise, can rise together with ball float, final ball float can clog and block lobe 4, and liquid level stops rising and is just desired body accumulated amount.The utility model structure is simple, and easy to operate, precision is high, and cost is low, is applicable to promote the use of on a large scale.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection domain of the present utility model.
