Abstract
The utility model discloses a dropper with a scale. The dropper comprises a straight tube and a soft sac, wherein the straight tube is provided with raised lines for indicating the scale or concave lines coated with colors inwardly; the whole straight tube is conical, and becomes thin from top to bottom; the straight tube and the soft sac are sleeved in a split way; the straight tube is made of transparent materials such as glass; and the straight tube and the soft sac can be made of transparent plastics to form an integral structure. Compared with the prior art, the dropper with the scale has the advantages that: due to the scale, the using amount of a chemical reagent is accurately taken at one time, so that experiments are accurate and standard.
Description
Technical field
The utility model relates to a kind of dropper, belongs to chemical experimental instrument.
Background technology
When carrying out chemical experiment, often can use dropper, dropper commonly used is to be made up of glass straight tube and the rubber bag tank that is enclosed within glass straight tube upper end, does not have scale above; Can only the dependence experience take chemical reagent, and students does not have too many experience, usually be otherwise get too much cause waste; Be that the amount of obtaining is not enough; Need take once more, just cause many errors once owing to take for twice, thereby can not get correct experimental result on student's the laboratory.
Summary of the invention
The utility model technical problem to be solved provides a kind of dropper that can once accurately take chemical reagent.
For solving this technical problem, the utility model provides a kind of dropper with scale, comprises straight tube and soft capsule, and said straight tube is provided with the salient line of sign scale or the concave of interior coating colour.
Said straight tube integral body is tapered, is tapered from top to bottom.
Said straight tube is the split type formation that is sleeved on soft capsule, and said straight tube is that transparent materials such as glass are processed.
Said straight tube and soft capsule integrative-structure for processing by transparent plastic.
Beneficial effect: the utility model compared with prior art owing to have scale, is easy to once get accurate chemical reagent consumption, makes the accurate more and standard of experiment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 straight tube, 2 soft capsules, 3 graduation marks.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Shown in Figure 1 is the structural representation of the utility model.
The utility model comprises straight tube and soft capsule.
Said straight tube is provided with the concave of the salient line that indicates scale, interior coating colour or the sign line in the portrayal.
Said straight tube integral body is tapered, is tapered from top to bottom.
The said straight tube of said straight tube is that transparent materials such as glass are processed.
Described soft capsule is by the one-time formed sphere that has an opening of soft materials such as rubber or olive-type etc.
The straight tube upper end that the opening of said soft capsule tightly is enclosed within.
Further, said straight tube and soft capsule are structure as a whole, and are processed by an injection moulding of other transparent materials such as plastics.
During use, compress soft capsule, discharge air, reagent bottle is goed deep in the lower end of dropper, slowly loosen the soft capsule that compresses after touching reagent, draw reagent, observe the graduation mark on the dropper straight tube simultaneously, take out dropper when waiting to reach required amount of reagent, accomplish reagent and take.
The utility model compared with prior art owing to have scale, is easy to once get accurate chemical reagent consumption, makes the accurate more and standard of experiment.
