Abstract
The utility model relates to a metering pipe which comprises an outer tube (1) and a core plug (4), and is characterized in that the chamber of the outer tube (1) is provided with the core plug (4) with a handle (6); the chamber is connected with a beam orifice (3) at the bottom, and is provided with a graduation horizontal line (5) on the external wall and an outer edging (2) at the top opening. The metering pipe can prevent the liquid from spotting on the wall, and the metering pipe has little residual amount, and high metering accuracy; the liquid metering accuracy of the metering pipe increases 20 times, compared with the liquid metering accuracy of the existing metering pipes.
Description
Affiliated technical field
The utility model relates to a kind of metering vessel, is the gauge line that is mainly used in the meters reagents precision specifically.
Background technology
Existing gauge line is the glass tube of an end band nipple, its reagent is freely to drip through glass tube to drop down, flow out from nipple, because the sense of glass tube hand rubbing is not round, the two ends thickness does not wait, several centimeters of vertical observed deviation, inwall is easy to hang, be stained with, residual, the segmental averaging value does not wait, and the impact analysis precision can't enter trace level.
Summary of the invention
In order to overcome the above-mentioned shortcoming that prior art exists, the purpose of this utility model has provided a kind of precision height, gauge line that residual quantity is little.
In order to achieve the above object, the technical solution of the utility model is: comprise outer tube, core plug, the outer tube inner chamber is provided with the core plug of band handle, and intracavity bottom is connected with beam orifice, and its outer wall is provided with scale, the overcoat limit that is provided with suitable for reading.The mutual driving fit of wall beyond the Great Wall of outer sleeve inner wall and core.The outer tube outer wall is all carved the 20 lattice capacity horizontal line of 1ml altogether.
The beneficial effects of the utility model are: according to the scale of glass tube, by the extruding ray, glass outer tube and glass core plug reach round d-axis to requiring, and mutual close joining, be not stained with wall, do not hang and drip, residual quantity is little, and the liquid magnitude accuracy improves 20 times than existing gauge line.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1, outer tube 1, overcoat limit 2, beam orifice 3, core plug 4, scale mark 5, handle 6.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
A kind of gauge line as shown in Figure 1 comprises outer tube 1, overcoat limit 2, beam orifice 3, core plug 4, scale 5, handle 6.With corresponding grinding iron staff the inwall of outer tube and the outer wall of core plug are ground, make its close joining, reach straight degree, the axial standard of circularity, upwards handle core plug is with in pulling, promptly suck a certain amount of reagent in the outer tube, promote band handle core plug downwards, discharge a certain amount of reagent to required container through beam orifice from outer tube.
Claims (3)
1, a kind of gauge line, comprise outer tube (1), core plug (4), it is characterized in that: described outer tube (1) inner chamber is provided with the core plug (4) of band handle (6), and intracavity bottom is connected with beam orifice (3), its outer wall is provided with scale horizontal line (5), the overcoat limit (2) that is provided with suitable for reading.
2, a kind of gauge line according to claim 1 is characterized in that: described outer tube (1) inwall and the mutual driving fit of core plug (4) outer wall.
3, a kind of gauge line according to claim 1 is characterized in that: described outer tube (1) outer wall is all carved the 20 lattice capacity horizontal line (5) of 1ml altogether.
