Abstract
The utility model discloses a graduated cylinder, which comprises a cylinder body (1), wherein a cylinder opening (2) is arranged on the upper end of the cylinder body (1); a retainer ring (3) is arranged below the cylinder opening (2); and the retainer ring (3) is provided with a concave surface (4) which faces to the cylinder opening (2). Because the retainer ring provided with the concave surface is arranged below the cylinder opening of the graduated cylinder, a reagent which flows down from the cylinder opening is received by the retainer ring and prevented from further flowing down after the graduated cylinder is used, a human body or a worktable is prevented from being polluted.
Description
Technical field
The utility model relates to a kind of graduated cylinder, belongs to the graduated cylinder technical field.
Background technology
In chemical test, graduated cylinder is indispensable experiment utensil, because after using graduated cylinder to measure reagent and transfer, cylindrical shell periphery at graduated cylinder is left over reagent easily, the reagent of being left over will pollute staff, though in the process that shifts, can avoid by proper operation, but when being placed on the workbench after shifting, reagent can flow to workbench along cylindrical shell, pollute workbench, thus the indirect pollution human body, in addition at transfering reagent and after placing, when going again to take graduated cylinder, the often also inevitable reagent that must run into the cylindrical shell periphery.
The utility model content
Technical problem to be solved in the utility model is that a kind of graduated cylinder that can prevent reagent contamination staff, workbench is provided.
The technical solution of the utility model: this graduated cylinder, comprise cylindrical shell 1, the upper end of cylindrical shell 1 is a nozzle 2, is provided with back-up ring 3 below nozzle 2, and concave surface 4 is arranged on the back-up ring 3, concave surface 4 is towards nozzle 2.
The utility model is by being provided with the back-up ring of concave surface below the nozzle of graduated cylinder, make that graduated cylinder uses after, caught by back-up ring from the reagent that nozzle flows down, prevent it further toward dirty, thereby avoided human body or workbench contaminated.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment of the present utility model: the structure of this graduated cylinder comprises cylindrical shell 1 as shown in Figure 1, and the upper end of cylindrical shell 1 is a nozzle 2, is provided with back-up ring 3 below nozzle 2, and concave surface 4 is arranged on the back-up ring 3, and concave surface 4 is towards nozzle 2.Remain in reagent on the nozzle 2 when dirty, promptly flow in the concave surface 4, be prevented from further toward dirty.Because residual amount of reagent is also few, therefore set back-up ring 3 sizes are little, do not hinder the normal use of graduated cylinder.
Claims (1)
- [claim 1] a kind of graduated cylinder comprises cylindrical shell (1), and the upper end of cylindrical shell (1) is nozzle (2), it is characterized in that: be provided with back-up ring (3) in the below of nozzle (2), concave surface (4) is arranged on the back-up ring (3), concave surface (4) is towards nozzle (2).
