Description

Technical Field

[0001] The utility model relates to the technical field of test tools, in particular to a reagent kit of resolubilizable reagents. Background Art

[0002] Reconstitution is a chemical term that refers to the process of re-dissolving a substance from a dry state under certain specific conditions and adding other substances to prepare a solution. In routine testing, some pharmaceutical products and other products are freeze-dried to prepare them into powder or blocks in order to improve storage convenience. When used, they need to be mixed and reconstituted with a reconstitution solution.

[0003] The existing experimental reconstitution operation process has the following disadvantages: the existing experimental reconstitution operation requires multiple components such as reconstitution solution, test tubes, syringes, etc. The reconstitution solution must first be extracted using a syringe, injected into the freeze-dried powder bottle for reconstitution, and then re-extracted and discharged into the test tube for use. The operation process is cumbersome, requires many tools, and is not convenient enough. For this reason, we propose a test kit for reconstitution reagents. Utility Model Content
