Abstract
The utility model relates to a chemical instrument, in particular to a dropper for liquid use. The dropper for micro determination comprises a glass dropper and a rubber cap placed on the upper end ofthe glass dropper, and is characterized in that the tube opening in the lower end has a circular edge and the tube body of the glass dropper has scales. The utility model has the advantages of simplestructure, convenient operation, protecting the dropper from damage to some extent and estimating better the dropping liquid amount.
Description
(1) technical field
The utility model relates to a kind of chemical apparatuses, particularly a kind of liquid dropper.
(2) background technology
Glue head dropper generally is used for drawing or dripping small amount of liquid reagent, and does not have the function of measuring capacity.When using glue head dropper to drip small amount of liquid, the experimenter normally adds the amount of liquid according to the mouth of pipe size estimation of glue head dropper, and general small-sized glue head dropper 30 drop of liquid are one milliliter, but numerical value and inaccuracy.
Because the material of glue head dropper glass tube is very thin, using when placing through regular meeting because firmly uneven, the mouth of pipe of glue head dropper is broken up, the mouth of pipe is increased, in this case, re-use glue head dropper and estimate and add solution and then do not have exact numerical values recited at all.
(3) summary of the invention
The utility model provides a kind of dropper of non-damageable microdetermination in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of dropper of microdetermination, the Capsule that comprises the glass dropper and be installed in glass dropper upper end, its special character is: the described glass dropper lower end mouth of pipe is provided with the annulus limit, on the body of glass dropper scale is arranged.
Scale described in the utility model is on the parallel tubes of glass dropper.
The glass dropper lower end mouth of pipe is provided with the annulus limit, virtually with the glass dropper edge thickening, the edge of Cai Yonging is an annular in addition, when it is contacted with Dropper stand or other article, if there is collision to produce, dissipation of ferees reduces the possibility that breaks up timely.
The body of glass dropper is provided with scale; purpose is to estimate the amount that drips as liquid; scale is arranged on the parallel tubes of glass dropper; with dropper in bottle during draw solution; only need make the sharp mouth of glass dropper stretch into solution gets final product; if the solution of drawing has corrosivity, can protect scale not to be corroded to a certain extent.
The utility model is simple in structure, and is easy to use, protects dropper not to be damaged to a certain extent, and appraisal that can be good drips the amount of liquid.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 glass dropper, 2 Capsules, 3 annulus limits, 4 scales.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.The Capsule 2 that this embodiment comprises glass dropper 1 and is installed in glass dropper 1 upper end, the described glass dropper 1 lower end mouth of pipe is provided with annulus limit 3, and scale 4 is arranged on the body of glass dropper 1; Described scale 4 is on the parallel tubes of glass dropper 1.
During use, the middle finger and the third finger are clamped glass dropper 1 part and are kept stable, push suction or the dripping quantity of Capsule 2 with control reagent with thumb and forefinger.When drawing reagent, the sharp mouth portion of glass dropper 1 is stretched in the reagent, scale 4 is in the parallel tubes position of glass dropper 1, can not be subjected to the pollution of reagent.
Use and finish, when placing dropper, the annulus limit 3 of the glass dropper 1 lower end mouth of pipe can maximum alleviation contact the collision that produces with other article, avoid the damage of glue head dropper to a certain extent.
Claims (2)
1. the dropper of a microdetermination, the Capsule (2) that comprises glass dropper (1) and be installed in glass dropper (1) upper end, it is characterized in that: described glass dropper (1) the lower end mouth of pipe is provided with annulus limit (3), and scale (4) is arranged on the body of glass dropper (1).
2. the dropper of microdetermination according to claim 1, it is characterized in that: described scale (4) is on the parallel tubes of glass dropper (1).
