Abstract

The utility model relates to a triangular flask with an inclined scale. Based on the original horizontal scale, two groups of inclined scales arranged in a fan shape are arranged on a flask body. Numerical figures are marked on the inclined scale to indicate the quantity of the residual liquid in the flask during pouring. A pair of circle marks is formed in the vicinity of the flask opening and used for adjusting the flow to pass through a pouring point during pouring. Compared with the prior art, the triangular flask provided by the utility model can read the quantity of the residual liquid in the flask during pouring and calculate the quality of the poured liquid, so as to conveniently pour the liquid with a certain quantity. The triangular flask overcomes the shortcoming that the flask in the prior art can not pour the liquid with a certain quantity as required.

Description

The triangular flask of band inclination scale

Technical field:

The utility model relates to a kind of Experiment on Microbiology triangular flask commonly used.

Technical background:

At present the triangular flask that the uses scale that do not tilt causes in the process of pouring liquid, can not read remaining amount of liquid in the bottle, can not accurately pour out certain amount of fluid.

Summary of the invention:

Technical problem to be solved in the utility model is: in order to overcome pouring liquid or the more loaded down with trivial details shortcoming of constant volume flowing fluid ratio that existing triangular flask exists, the utility model provides a kind of triangular flask that has the inclination scale, and pouring liquid or constant volume liquid are once finished.

The utility model technical scheme that is adopted of dealing with problems is: on the basis of in the past triangular flask horizontal scale, increased the inclination scale of fan-shaped array, the inclination scale has two groups, and one group is high power capacity inclination scale, and one group is low capacity inclination scale; Graduation mark in pairs; Be marked with numeral on the inclination scale; A pair of circles mark is arranged near bottleneck, certain that is used to regulate the liquid level place when toppling over to graduation mark at same horizontal plane; Inclination scale on the bottle can adopt not synteny or different colours to be distinguished conveniently to read.

The beneficial effect that the utility model brings is: this triangular flask is compared with existing product, owing to just can easily read the raffinate scale of construction in the bottle in toppling process, so can once topple over certain quantity of fluid or constant volume liquid, the saving of labor, saves time.

Description of drawings:

Fig. 1 is the front elevation of the triangular flask of band inclination scale, and Fig. 2 is the back view of the triangular flask of band inclination scale.

The specific embodiment:

Fig. 1 is the front elevation of the triangular flask of band inclination scale, and Fig. 2 is the back view of the triangular flask of band inclination scale.(1) is first pour(ing) point among the figure, and it is positioned at the bottleneck somewhere; (2) are second pour(ing) points among the figure, and it is positioned under first pour(ing) point, bottleneck (6) bottom; Draw two groups of inclination scales (4) through these two pour(ing) points on triangular flask, two groups of inclination scales (4) can adopt not synteny or different colours to be distinguished; The position at inclination scale (4) place will be according to the actual position at liquid level place when toppling over, and goes up with numeral at inclination scale (4) and to indicate the raffinate scale of construction; " a 0 " graduation mark is arranged in the inclination scale (4), and it is the tangent line when tangent by a certain plane of pour(ing) point (2) and body (7); Other inclination scales (4) in pairs, every pair of numerical value that go up to indicate is identical, and with plane (9) the mirror image symmetry at the place, axis (8) of " 0 " graduation mark and triangular flask, one in the triangular flask front, another is at the triangular flask back side; A pair of identical circles mark (3) is arranged near pour(ing) point (2) and bottleneck, and they are with plane (9) mirror image symmetry; The amount of bottle liquid when horizontal scale (5) is used for reading the triangular flask horizontal positioned.When pouring liquid, the rotary triangle bottle makes two circles mark (3) and operator's eyes on a horizontal linear, at this moment liquid stream can be accurately through two pour(ing) points, the edge, front and back of observed liquid level overlaps with certain inclination scale (4) to identical numerical value during pouring liquid, numerical value on this inclination scale (4) is the raffinate scale of construction in the bottle at this moment, total amount deducts surplus and is the amount of liquid of pouring out, and can topple over certain amount of fluid and the amount of knowing remaining liq in the bottle so easily.

Claims

1. triangular flask, this triangular flask is characterised in that, on the basis of previous level scale, has increased the inclination scale of two groups of fan-shaped array on the bottle; One group of inclination scale when being high power capacity wherein, the inclination scale when also having a group to be low capacity; Be marked with numeral on the inclination scale; A pair of circles mark is arranged near bottleneck; Inclination scale on the bottle can adopt not synteny or different colours to be distinguished.
