Embodiment Construction

[0007] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0008] see figure 1 , a measuring cylinder, comprising a cylinder body 1, a groove 3 is arranged around the outer wall of the cylinder body 1 near the mouth of the cylinder body, the opening of the groove 3 faces the mouth of the cylinder body, and a transparent rubber layer is wrapped on the outer wall of the cylinder body 1 2.

[0009] When the present invention is used, when the reagent remaining in the cartridge mouth flows down, it flows into the groove 3 and is prevented from flowing down further. At the same time, the transparent rubber layer 2 protects the measuring cylinder so that it is not easy to break and does not affect the experimental results; it also has an anti-slip function to a certain extent, so that the measuring cylinder is not easy to slip when it is taken; the transparent rubber layer 2 is made of elastic rub...

Abstract

The invention discloses a graduated cylinder which comprises a barrel, wherein the part of the barrel, close to the barrel port, is provided with a groove around the outer wall of the barrel; the opening of the groove faces the barrel port; and the outer wall of the barrel is wrapped with a transparent rubber layer. The graduated cylinder is practical, the part of the graduated cylinder, close to the barrel port, is provided with a groove in which a reagent flowing down from the barrel port flows after use of the graduated cylinder, so that the reagent is prevented from flowing further, thereby preventing a human body or a work platform from being polluted; in addition, the design of a transparent rubber layer meets the requirement on a glass container during an experiment, so that the cylinder can not be broken easily and the transparent rubber layer also has the skidproof function.

Description

technical field [0001] The invention relates to a measuring cylinder, which belongs to the technical field of chemical testing. Background technique [0002] In chemical experiments, graduated cylinders are indispensable experimental equipment. After measuring and transferring reagents with graduated cylinders, reagents are easily left on the periphery of the cylinder of the graduated cylinders, and the remaining reagents will pollute the hands. Although they can be passed during the transfer process Correct operation to avoid, but when placed on the workbench after transfer, the reagent will flow to the workbench along the cylinder, contaminate the workbench, thereby indirectly polluting the human body. In addition, after the reagent is transferred and placed, it is often It is also unavoidable to encounter reagents on the periphery of the cylinder. In addition, most measuring cylinders are made of glass. Glass instruments are too fragile and will break if you don’t pay at...
