Abstract
A kind of rectifier that can correct cylinder scale is the utility model is related to, including base, scale bar and scale bar, its material are glass material, can avoid the errors caused by extraneous factor such as corrosion.Base is spill, and its internal diameter and measurement graduated cylinder outside dimension are adapted, graduated cylinder is put into inside rectifier base, the height of rectifier base is consistent with the thickness of graduated cylinder base, when graduated cylinder is put into rectifier base, the zero graduation and measurement graduated cylinder zero graduation of rectifier are in same level.In actual mechanical process, the purpose of liquid volume in accurate measurement quantity cylinder instead of the scale of graduated cylinder itself, can be reached according to adjustable stem high scale, solve due to cylinder scale it is inaccurate caused by experimental error.
Description
Technical field
Laboratory auxiliary Tools Technology is the utility model is related to, specifically a kind of school that can correct cylinder scale
Positive instrument.
Background technology
Graduated cylinder is the common glass apparatus that laboratory is used for weighing liquid volume, during use usually, Hen Duoren
Graduated cylinder is put into baking oven and dried, due to the principle expanded with heat and contract with cold, some changes can occur for the scale of graduated cylinder in the course of time, simultaneously
When alleged quantity of fluid is in acid or alkaline, also it can make scale that some changes occur.For the very high experiment of precise requirements, meeting
There is error in the liquid volume for causing to weigh, cause experimental result inaccurate.The present invention designs one kind according to above deficiency can
To correct the rectifier of cylinder scale.Avoid due to cylinder scale it is inaccurate caused by error.
The content of the invention
The purpose of this utility model is to overcome existing deficiency, a kind of instrument that can correct cylinder scale of invention.This
Utility model practicality is stronger, is applicable common lab, enterprise laboratory and its a series of may need to weigh using graduated cylinder
The place of liquor capacity.
To achieve these goals, the technical solution adopted in the utility model is as follows：It is a kind of to correct cylinder scale
Rectifier, including base（1）, adjustable stem（2）And scale bar（3）, material is glass material.It is characterized in that base（1）For
Spill, and its internal diameter and measurement graduated cylinder outside dimension are adapted so that graduated cylinder can put rectifier base into（1）The inside；School
Positive instrument base（1）Height it is consistent with the thickness of graduated cylinder base, when graduated cylinder is put into rectifier base, the zero of rectifier
The zero graduation of scale and measurement graduated cylinder is in same level.Scale bar（2）On scale be master scale, and during use
Scale bar（3）Must be with scale bar（2）Vertically.Scale bar（3）Length for scale bar to the distance in the base center of circle, ensure surveying
During amount, scale bar can accurately mark the height of liquid level.
Brief description of the drawings
Fig. 1 is the schematic diagram of cylinder scale rectifier.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail.
With reference to figure 1, the utility model is related to a kind of rectifier that can correct cylinder scale includes base（1）, adjustable stem
（2）And scale bar（3）.In specific operation process, graduated cylinder is put into base（1）In, utilize scale bar（3）To determine liquid level
Height and the corresponding scale on adjustable stem.Due to adjustable stem（2）Zero graduation and the zero graduation line of measurement graduated cylinder be in same
, can be according to adjustable stem on one horizontal plane（2）Scale replace the scale of graduated cylinder itself, reach liquid in accurate measurement quantity cylinder
The purpose of volume, solve the problems, such as that cylinder scale is inaccurate.
Claims (2)
1. a kind of rectifier that can correct cylinder scale, including base（1）, scale bar（2）And scale bar（3）, its feature
For：Base（1）For spill, and its internal diameter and measurement graduated cylinder outside dimension are adapted so that graduated cylinder can put rectifier bottom into
Seat（1）The inside；Rectifier base（1）Height it is consistent with the thickness of graduated cylinder base, when graduated cylinder is put into rectifier base
When, the zero graduation and measurement graduated cylinder zero graduation of rectifier are in same level；Scale bar（2）On scale be master scale,
And scale bar during use（3）Must be with scale bar（2）Vertically；Scale bar（3）Length be scale bar to the base center of circle
Distance, ensure during measurement, scale bar can accurately mark the height of liquid level.
