Abstract
The utility model relates to a kind of anti-suck glue head dropper, comprise Capsule and glass dropper, described Capsule is arranged on the upper end of glass dropper, the junction of described Capsule and glass dropper is provided with thread bush, described thread bush is screwed together by screw thread and glass dropper, be provided with air inlet pipe near the junction of thread bush glass dropper, the middle and lower part of described air inlet pipe is provided with the anti-down suction pipe that a radius is less than air inlet pipe radius; Described anti-down suction pipe is connected with air inlet pipe by multiple connecting rod, and the cavity between air inlet pipe with anti-down suction pipe communicates with air inlet pipe.By being provided with anti-down suction pipe, can effectively prevent liquid from blowing back in Capsule, convenient to use in chemical experiment, be convenient to Students ' Learning and operation.
Description
Technical field
The utility model relates to chemical apparatuses apparatus field, particularly relates to a kind of anti-suck glue head dropper.
Background technology
Glue head dropper is also known as Capsule dropper, and it is a kind of instrument for drawing or drip a small amount of liquid reagent, and glue head dropper is made up of Capsule and glass dropper, has straight shape, directly shape to have buffering ball and bending to have several forms such as buffering ball.The specification of glue head dropper represents with pipe range, and commonly using is 90 mm, 100 mm 2 kinds.Glue head dropper should be noted that following item in use: 1, holding method clamps glass part to keep stable with middle finger and the third finger, extrudes glue head to control suction or the dripping quantity of reagent with thumb and forefinger; 2, during glue head dropper liquid feeding, container can not be stretched into, more can not contacting container.Vertically should be suspended on 0.5 cm place above container; 3, can not be inverted, can not lie against on desktop.Should to insert in clean bottle or in vitro; 4, after being finished, wash immediately.Forbid not clean and just draw another reagent.Dropper on drop bottle is without the need to cleaning; 5, Capsule and glass dropper in conjunction with closely air tight, if Capsule is aging, will be changed in time; 6, glue head dropper is to when in vitro dripping poisonous or mordant liquid, and this improved pipette tip allows contact inboard wall of test tube; If 7 drop bottles are furnished with dropper, then this dropper is that drop bottle is special, can not draw other liquid.Can not cross-reference, also unavailable clear water flushing.
Current glue head dropper can not be horizontal, more can not be inverted, otherwise the liquid in dropper will blow back in sacculus glue head, causes corrosion to the sacculus glue head that rubber makes.But test student not note, incorrect use glue head dropper at every turn, cause glue head dropper can not be used by the liquid corrosion that blows back into because of sacculus glue head.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of anti-suck glue head dropper.
The utility model is achieved through the following technical solutions:
A kind of anti-suck glue head dropper, comprise Capsule and glass dropper, described Capsule is arranged on the upper end of glass dropper, the junction of described Capsule and glass dropper is provided with thread bush, being screwed together by screw thread and glass dropper of described thread bush, be provided with air inlet pipe near the junction of thread bush glass dropper, the middle and lower part of described air inlet pipe is provided with the anti-down suction pipe that a radius is less than air inlet pipe radius; Described anti-down suction pipe is connected with air inlet pipe by multiple connecting rod, and the cavity between air inlet pipe with anti-down suction pipe communicates with air inlet pipe.
As optimal technical scheme of the present utility model, described connecting rod and air inlet pipe, anti-down suction pipe adopt same material to make.
As optimal technical scheme of the present utility model, the body of described glass dropper is provided with graduation mark from top to bottom, can draw or drip the amount of required reagent more accurately, brings larger guarantee to the accuracy of experiment.
As optimal technical scheme of the present utility model, described air inlet pipe is installed with anti-down suction pipe is concentric.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by being provided with anti-down suction pipe, can effectively prevent liquid from blowing back in Capsule, convenient to use in chemical experiment, be convenient to Students ' Learning and operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-Capsule; 2-glass dropper; 3-thread bush; 4-air inlet pipe; The anti-down suction pipe of 5-; 6-connecting rod; 7-cavity; 8-graduation mark.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
