Colorimetric tube sealing cap

Abstract

The invention discloses a colorimetric tube sealing cap for enabling a colorimetric tube plug to be fixed at a colorimetric tube opening. The colorimetric tube sealing cap comprises a flexible cap body and a binding belt, wherein the flexible cap body comprises a center part and a periphery part, the center part corresponds to the colorimetric tube plug, and the periphery part can be close to the lateral wall of the colorimetric tube; the binding belt is connected to the periphery part so as to bind the periphery part on the lateral wall of the colorimetric tube; a fixing component for enabling the binding belt to be fixed is arranged on the binding belt. According to the arrangement, the colorimetric tube sealing cap provided by the invention can save time and labor when the colorimetric tube sealing cap adopts the fixed colorimetric tube plug, materials can also be saved, and the fixing reliability of the colorimetric tube plug can be ensured.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a colorimetric tube sealing cap. Background technique [0002] In the laboratory, the high-temperature digestion and sterilization of reagents is carried out in various types of colorimetric tubes. After plugging the mouth of the colorimetric tube with a stopper and wrapping the mouth of the colorimetric tube with gauze, traditionally, cotton thread is often used. Second winding and binding enable the gauze to fix the colorimetric tube plug and make it closely connected with the colorimetric tube body to ensure that the reagent is sealed in the colorimetric tube, thereby preventing the reagent from washing out the colorimetric tube plug at high temperature, thereby achieving the purpose of the experiment . [0003] However, using the above method to fix the plug of the colorimetric tube, not only the winding and bandaging of the cotton thread will waste the workin...

Problems solved by technology

[0003] However, using the above method to fix the plug of the colorimetric tube, not only the winding and bandaging of the cotton thread will waste the working time of the scientific research personnel, time-consuming and labor-intensive, but also the cotton thread tends to become fragile and easy to break at high temperature, which will easily cause the reagent in the colorimetric tube to be damaged. Breaking through the plug of the colorimetric tube will affect the progress of the experiment. In addition, the cotton thread material used to wind the colorimetric tube cannot be reused, which will cause a waste of resources

[0004] Therefore, how to solve the time-consuming and labor-intensive problems of fixing the colorimetric tube plug in the prior art, and the fixing reliability of the colorimetric tube plug is relatively poor, and the problem of waste of materials has become an important technical problem to be solved by those skilled in the art.
