Abstract
The invention discloses a kind of graduated scale for measuring colony diameter, it comprises blade (8) and scale (1), blade (8) is equilateral right-angle triangle, and respectively there is one group of scale (1) inner side of two square edges, and two groups of scales (1) intersect at interior right-angled apices (2).The present invention need not measure 2 times, do not need yet by double for observed value just can simultaneously, the diameter that directly reads vertical direction two bacterium colonies is long, and also reduces the size of graduated scale in design, namely saved material, be easy to operate again quick, reduce measuring error.
Description
Technical field
The present invention relates to a kind of graduated scale.
Background technology
The medicament of the field chemical prevention of Plant diseases selects Foundation on the Chemicals of indoor, Chemicals chooses the sterilant suppressing target pathogenic bacteria growth result good, and the standard evaluating its power needs to measure the colony diameter of growth on culture dish, calculate and compare.The method of usual measurement colony diameter is by common ruler through colony growth center, and two colony diameters measuring vertical direction according to right-angled intersection method respectively get all worth colony diameter again.This measuring method is more loaded down with trivial details, each colony diameter needs measurement just can calculate for twice, when measurement number workload of many times can be larger, and during the diameter of second time measurement vertical direction, the central position chosen can change because of unmarked, the error causing colony diameter to be measured becomes large, and for the medicament that fungistatic effect is more or less the same, calculation result may make the two actual inhibiting rate put upside down.Common graduated scale, because of defect itself, in the process measuring colony diameter, can make that experiment becomes complicated, error becomes large and efficiency reduces, can not meet the needs of actual measurement.The graduated scale quick and precisely can measuring colony diameter is not also had in current laboratory.
Summary of the invention
The technical problem to be solved in the present invention:, for the deficiency of existing graduated scale, provide a kind of simple to operate, accuracy rate is high, reading is fast graduated scale for measuring colony diameter.
Technical solution of the present invention:
For measuring a graduated scale for colony diameter, it comprises blade and scale, and blade is equilateral right-angle triangle, and respectively there is one group of scale the inner side of two square edges, and two groups of scales intersect at interior right-angled apices.
Scale value on scale is the twice of physical length.
Within on blade, right-angled apices is the rectification arc that there is 1/4 circular arc in the center of circle.
Blade material is transparent PVC.
Beneficial effect of the present invention: 2 times need not be measured, do not need yet by double for observed value just can simultaneously, the diameter that directly reads vertical direction two bacterium colonies is long, and also reduces the size of graduated scale in design, namely saved material, be easy to operate again quick, reduce measuring error.There is one to take summit as 1/4 circular arc in the center of circle between vertical scale line, be rectification arc, there is correcting function.According to the growth vestige of pathogenic bacteria bacterium colony on culture dish generally in concentrically ringed feature, when this circular arc to overlap with bacterium colony ring or each other concentric(al) circles time, interior right-angled apices is the bacterium colony center of circle, now, it is long that the maximum outer shroud of colony growth and the intersection point reading average of both sides graduated scale are colony diameter, utilize correct arc can quick position bacterium colony center, accelerate measuring speed, improve measurement accuracy.
The present invention has the advantages such as reasonable in design, structure simple, practicality is laborsaving, easy to use, and production cost is low, has good Transformation Application prospect.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is using method schematic diagram of the present invention.
embodiment:
Preferably embodiment is as shown in Figure 1 in the present invention, the graduated scale provided is made up of blade 8, vertical scale 1 and rectification arc 3, and blade 8 is equilateral right-angle triangles, and the main material of blade 8 is transparent PVCs, there is high transparency, good weatherability, the advantage that price is lower.There are two orthogonal scales 1 inner side of blade 8 two square edges, and its scale value is 2 times of physical length, and two scales 1 intersect at interior right-angled apices 2, correct arc 3 be within right-angled apices 2 be 1/4 circular arc in the center of circle.
The scale value of scale 1 is 2 times of physical length, and direct reading when being convenient to measure, does not need measuring result double.
Scale 1 is positioned on two vertical square edges, is convenient to read two diameters long simultaneously, avoids repetitive operation, increase work efficiency.
Correct the position that arc 3 can find out bacterium colony center quickly and accurately, reduce measuring error, improve the accuracy rate of result.
As Fig. 2, during use, first is fitted in the back side in the front and culture dish 4 that are used for the graduated scale measuring colony diameter, interior right-angled apices 2 is moved to bacterium colony immediate vicinity, trimming scale chi, rectification arc 3 is overlapped with bacterium colony ring 5 or in concentric(al) circles time, now two scales 1 have two intersection points 6 and 7 with the maximum bacterium colony ring of colony growth, direct reading, gets the colony diameter that the two average is this bacterium colony.The present invention has the advantages such as reasonable in design, structure simple, practicality is laborsaving, easy to use, and the laboratory being particularly suitable for relating at plant pathology etc. microorganism culturing is promoted the use of.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the scope that can expect easily or replacement, all should be encompassed within protection scope of the present invention.
Claims (2)
1. one kind for measuring the graduated scale of colony diameter, it comprises blade (8) and scale (1), it is characterized in that: blade (8) is equilateral right-angle triangle, article two, respectively there is one group of scale (1) inner side of square edge, two groups of scales (1) intersect at interior right-angled apices (2), within blade (8) is upper, right-angled apices (2) has the rectification arc (3) of 1/4 circular arc for the center of circle, and the scale value on scale (1) is the twice of physical length.
