Abstract

A kind of Experiment of Analytical Chemistry gas sampling assembly, belong to chemical experiment clothing arts, solve Problems existing when using absorption tube collection experimental gas sample, it comprises a horizontally disposed U-tube, arrange a spherical container to be respectively communicated with by U-tube at the two ends of U-tube, the sideline, downside of U-tube and the concordant setting in summit, downside of two spherical containers, the volume that each spherical container is positioned at the part of more than U-tube is greater than the volume of U-tube, two spherical containers are provided with the valve for connection rubber tube, valve is arranged on the upside vertex position of two spherical containers, the utility model is used for gas sampling.

Description

Experiment of Analytical Chemistry gas sampling assembly

Technical field

The utility model belongs to chemical experiment clothing arts, is specifically related to a kind of Experiment of Analytical Chemistry gas sampling assembly.

Background technology

Analytical chemistry gas divides in plate education experiment process, first need to use absorption tube and sampling thief to be connected by sebific duct and gather experimental gas sample, absorption tube and the necessary exact connect ion of sampling thief, if the air intake opening of absorption tube is connected with the air intake opening of sampling thief by mistake, absorbing liquid in absorption tube can be drawn onto sampling thief inside by sampling thief, damage the strength members such as the asepwirator pump of sampling thief, the loss caused is very big, being easy to occur such problem because of lack of experience when gathering gas sample by its student, having a strong impact on teaching; And absorption tube self cannot stand surely, must vertically be placed on special shelf, otherwise absorption tube is toppled over, absorbing liquid is also easily drawn onto in sampling thief.

Summary of the invention

The purpose of this utility model be in order to solve use absorption tube gather experimental gas sample time Problems existing, provide a kind of Experiment of Analytical Chemistry gas sampling assembly, its technical scheme is as follows:

A kind of Experiment of Analytical Chemistry gas sampling assembly, it comprises a horizontally disposed U-tube, arrange a spherical container to be respectively communicated with by U-tube at the two ends of U-tube, the sideline, downside of U-tube and the concordant setting in summit, downside of two spherical containers, the volume that each spherical container is positioned at the part of more than U-tube is greater than the volume of U-tube, two spherical containers are provided with the valve for connection rubber tube, valve is arranged on the upside vertex position of two spherical containers.

The beneficial effects of the utility model are: the valve on whichever spherical container is connected with the air intake opening of sampling thief, and the absorbing liquid in this device all can not be drawn onto sampling thief inside by sampling thief, can not damage the strength members such as the asepwirator pump of sampling thief; And do not need to be placed on special shelf, this device only needs to be placed on arbitrary plane, use of conveniently imparting knowledge to students.

Accompanying drawing illustrates:

Fig. 1 is perspective view of the present utility model;

Fig. 2 is the front elevation of Fig. 1;

Fig. 3 is the right view of Fig. 1.

embodiment:

With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of Experiment of Analytical Chemistry gas sampling assembly, it comprises a horizontally disposed U-tube 1, arrange a spherical container 2 to be respectively communicated with by U-tube 1 at the two ends of U-tube 1, the sideline, downside of U-tube 1 and the concordant setting in summit, downside of two spherical containers 2, the volume that each spherical container 2 is positioned at the part of U-tube more than 1 is greater than the volume of U-tube 1, two spherical containers 2 are provided with the valve 3 for connection rubber tube, valve 3 is arranged on the upside vertex position of two spherical containers 2.

A kind of Experiment of Analytical Chemistry gas sampling assembly, the transparent or semitransparent glass material of its overall employing.

Using method: first add absorbing liquid in this device, absorbing liquid adds to the sideline, upside flushing with or slightly higher than U-tube 1 with the sideline, upside of U-tube 1, then uses sebific duct to be connected with the air intake opening of sampling thief by any one valve 3 and can open sampling thief and sample.
