Description

Laboratory liquid dispensing device

technical field

The utility model relates to a dispensing device, in particular to a laboratory liquid dispensing device.

Background technique

In chemical or biological laboratories, it is often necessary to dispense liquids into small-capacity containers for students or teachers to use in experimental activities. The liquid here is sometimes a prepared solution, sometimes an original reagent, and often even a volatilized toxic reagent. When experimenters or teachers prepare experiments for students, they need to distribute liquids into a large number of small containers, such as narrow-mouth bottles, test tubes, drop bottles and other small-caliber containers.

At present, the liquid dispensing in the laboratory mainly relies on the funnel. When using it, the dispensing personnel need to hold the funnel with one hand and hold the container containing the liquid to be dispensed with the other, so that there is no extra hand to remove or cover the receiving liquid container. No cap or dropper, and no hands to hold the small container that receives the liquid. This not only leads to long dispensing time, but also causes bodily harm to the staff because the dispensing liquid is exposed to the air for a long time to volatilize. What's more, when subpackaging, the small container is toppled over due to being unable to support the receiving small container, and the liquid spills out. At the same time, when using a funnel to move from one receiving container to another, it is inevitable that part of the liquid will drop onto the table.

Contents of the invention

The technical problem to be solved by the utility model is to provide a simple, fast and easy-to-operate laboratory liquid dispensing device.

In order to solve the above-mentioned technical problems, the utility model is achieved through the following technical solutions: the laboratory liquid dispensing device includes a container body for dispensing liquid, and the container body is a cylindrical vessel with an opening at the upper end. The opening of the container body is provided with a container cover matching the opening, and a handle is provided on the side of the container body, and a button for opening the container cover is provided on the handle. Under normal circumstances, the container cover is stuck on the opening of the container body , when the container cover needs to be opened, press the button on the handle; the side of the container body is also provided with a branch pipe communicating with the container body, the branch pipe is located on the side corresponding to the handle, and the branch pipe passes through the The threaded connection has a detachable guide tube; when dispensing the liquid in the container body, the guide tube is connected to the liquid branch pipe, the container cover is closed on the container body, the container body is lifted by the handle, and the belt in the container body is dispensed. As the operator tilts the container body, the liquid flows out along the liquid branch pipe and the guide tube, and is distributed to other containers.

Preferably, the liquid branch pipe is arranged obliquely upward and forms an included angle with the container body, and the angle range of the included angle is 35°-50°, which can prevent the liquid to be dispensed in the container body from overflowing along the liquid branch pipe.

Preferably, the mouth of the draft tube is in the shape of a "7", which prevents the liquid from flowing too fast and spilling out when dispensing the liquid.

Preferably, the container body is a transparent container, which can be made of glass or plastic material as required, so as to facilitate observation of the liquid in the container body.

Preferably, the outer wall of the container body is marked with a scale indicating the volume, and the dispensing device can be used to prepare a solution that does not require high concentration accuracy.

Compared with the prior art, the advantages of the utility model are: the device of the utility model is simple, quick and safe to operate, and can effectively prevent the volatilization and leakage of the subpackaged liquid, and is aimed at poisonous chemical reagents. The liquid can protect the health of the operator; the detachable guide tube is convenient for cleaning the residual liquid in the guide tube and the branch pipe, and it takes up little space and is easy to place; it can be prepared by marking the scale on the outer wall of the container body to indicate the volume Solutions that do not require high concentration accuracy have a wider range of applications.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:

The laboratory liquid dispensing device shown in Fig. 1, Fig. 2 and Fig. 3 comprises a cylindrical container body 1 made of glass with an opening at the upper end, the opening on the container body 1 is provided with a Open container cover 2, the side of container body 1 is also provided with the handle 3 that is connected with container body 1, handle 3 is provided with a button 4 that is used to open or close container cover, also is provided with on the side of container body A liquid branch pipe 5 inclined upward by 45° is installed and corresponds to the handle 3. The liquid branch pipe 5 communicates with the container body 1, and the liquid branch pipe 5 is threaded with a "7"-shaped guide pipe. 6.

When injecting the liquid that needs to be divided into the container body 1, first press the button 4, open the container cover 2 (as shown in Figure 1), inject the liquid, and close the container cover 2 after the injection is completed (as shown in Figure 2), the operator uses the handle 3 The liquid to be divided into the container body 1 is poured, and the liquid flows along the branch pipe 5 and the diversion tube 6, and the mouth of the diversion tube 6 is divided into the small container to be divided. The container cover 2 is always closed to prevent the irritating or toxic gas of the liquid to be dispensed from volatilizing, which affects the health of the operator, and the mouth of the draft tube 6 is smaller to prevent the liquid to be dispensed from dripping out.

The outer wall of the above-mentioned container body 1 is also marked with a scale 7 indicating the volume, and the liquid dispensing device can be used to prepare a solution that does not require high concentration accuracy.

It should be emphasized that: the above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Any simple modification, equivalent change and Modifications still belong to the scope of the technical solution of the utility model.
