Abstract

The utility model discloses an anti-splash conical flask, which comprises a conical flask (1) and a hopper (2) which can be steadily placed on a flask mouth of the conical flask (1), and is characterized in that a 120-145 degree bending angle (4) is arranged between a conduit (3) and the hopper (2), and the conduit (3) goes deep into the conical flask from the lower end of the hopper which is arranged on the flask mouth of the conical flask. The anti-splash conical flask has the advantages that when strong acid or alkali solution needs to be added into the conical flask, liquid can downwardly flow to the conduit along the hopper, and then flows into the conical flask through the side wall of the conical flask by passing through the bended conduit. The anti-splash conical flask prevents the strong acid or the alkali solution from splashing during the adding process to cause accidents, and accords with operating instruction that the strong acid or the alkali solution flows in along with the side wall of the conical flask when being added.

Description

A kind of anti-conical flask that spills

Technical field

The utility model belongs to the apparatus of clinical laboratory's use of medical institutions, and definite saying is a kind of anti-conical flask that spills.

Background technology

The conical flask that hospital laboratory, clinical laboratory use all is that the uncovered lid that both do not have does not have other servicing unit yet, like this, when in flask, pouring strong acid or highly basic class or other liquid solution into, sometimes cause the accident because misoperation produces to spill, certain operations person can not pour the liquid such as acid solution or alkali lye into according to rules owing to misoperation along the flask sidewall.In order to overcome this problem, designer of the present utility model has done in earnest research, has proposed goal of the invention of the present utility model.

Summary of the invention

Goal of the invention of the present utility model can not prevent rationally that for the conical flask that overcomes present use the deficiency that liquid spills from putting forward.A kind of anti-conical flask that spills namely is provided.

Technical solution of the present utility model is to realize like this, the conical flask that should anti-spill, have conical flask (1) and can stablize the funnel (2) that is positioned on its bottleneck, it is characterized in that being deep in the funnel lower end on the conical flask bottleneck and have one 120 degree between the conduit (3) of conical flask inside and the funnel to the angle of bends (4) of 145 degree.

Useful technique effect of the present utility model is: when adding the solution such as strong acid or highly basic in the conical flask when needs, liquid can flow to conduit downwards along funnel, then flow into conical flask inside through crooked conduit through the sidewall of conical flask.Not only avoided strong acid or strong base solution in the process that adds, to spill and caused the accident, met again the solution such as strong acid or highly basic and add the operational procedure that will flow into along the sidewall of conical flask.

Description of drawings

Accompanying drawing is structural profile schematic diagram of the present utility model.Sequence number in the accompanying drawing is: 1, conical flask, 2, funnel, 3, conduit, 4, angle of bend.

The specific embodiment

Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, the anti-conical flask that spills of this kind, have conical flask (1) and can stablize the funnel (2) that is positioned on its bottleneck, it is characterized in that being deep in the funnel lower end on the conical flask bottleneck and have one 120 degree between the conduit (3) of conical flask inside and the funnel to the angle of bends (4) of 145 degree.

During use, place funnel the conical flask mouth inner, because the effect of angle of bend, conduit is towards the flask inwall, acid solution, alkali lye or other liquid are poured into along funnel, like this, no matter how to topple over, the outer wall of funnel has played an effect that capping stops, with the liquid obscures that splashes get off, simultaneously, liquid flows on the inwall of flask through conduit, enters flask interior and participates in chemical reaction, and the liquid such as acid, alkali lye enter after the test tube, then funnel can be taken off, carry out next step experimental implementation.

Claims

1. anti-conical flask that spills, have conical flask (1) and can stablize the funnel (2) that is positioned on its bottleneck, it is characterized in that being deep in the funnel lower end on the conical flask bottleneck and have one 120 degree between the conduit (3) of conical flask inside and the funnel to the angle of bends (4) of 145 degree.
