Compression type washing device for experimental analysis

Abstract

The invention relates to a compression type washing device for experimental analysis. The compression type washing device comprises a base, sliding wheels and a box; a handle, a pressure meter and a cover are fixedly installed at the top of the box; and the cover is provided with an infusion flexible pipe, and one end of the infusion flexible pipe extends into the box and is in contact with the inner wall of the bottom of the box. According to the compression type washing device for experimental analysis, the box is improved, the storage volume of a solvent is improved, and damage caused by too-large pressure in a container is avoided, different cleaning solvents can be contained, and the washing effect of different pollutants is achieved; a foot rest and a one-way valve compression pump are matched, so that the solvent conveying effect is achieved; through the base with the sliding wheels, convenience is brought to movement at will, and operation is easy and convenient; and filling can be carried out after the cover is opened, and time and labor are saved.

Description

technical field [0001] The invention belongs to an experimental device used for sample transfer or vessel cleaning in analytical chemistry, relates to the technical field of chemical laboratory cleaning devices, in particular to a pressurized cleaning device for experimental analysis. Background technique [0002] Wash bottle is a container commonly used in analytical laboratories, used for quantitative transfer of solutions, washing and transfer of precipitates or rinsing utensils. Ordinary washing bottles are mainly composed of a container filled with cleaning solvent and a nozzle that can spray out a fine liquid stream. There are two types of common washing bottles: blow-out type and squeeze type. Wherein, the blow-out type washing bottle is a glass product, which is easily broken and difficult to operate, which limits its scope of application. Therefore, most of the washing bottles commonly used in the laboratory are extrusion-type, with a capacity of 125-1000mL. The c...

Problems solved by technology

Among them, the blow-out type washing bottle is made of glass, which is easy to break and difficult to operate, which limits its scope of application.

Therefore, most of the washing bottles commonly used in the laboratory are extrusion-type, with a capacity of 125-1000mL. The cleaning solvent is sprayed out by squeezing the plastic bottle body to generate pressure. After each use of the cleaning solvent, it needs to be refilled, which is time-consuming and laborious. It cannot meet the batch transfer of a large number of samples or the batch rinsing of a large number of utensils

Although the utility model patent of "a washing bottle" with the application number ZL201220560028.7 provides a partial solution to the above problems, the stainless steel material it uses limits its scope of use, because it contains a large amount of trace elements, which will cause the test sample Pollution affects the accuracy of the experiment, so it cannot be used in laboratory analysis and testing operations, and many acidic solvents will cause corrosion

The above patents cannot monitor the pressure in the washing bottle in real time through the pressure gauge, and there is no safety pressurization valve, which has certain potential safety hazards

Similarly, when there is too much solution in the device, it takes time and effort to move
