When testing, the cap is opened, a sampling capillary is inserted to suck solution for testing. There is a risk of cross-contamination when using capillary in different solutions. The laboratory dust is easy to enter the solution and contaminate it, and the solution is also easy to evaporate and change the concentration.
[0004] In actual process, standard solution is not used at one time. To avoid waste, the cap is usually tightly closed and stored in a refrigerator. When used next time, it is taken out and placed at room temperature before use. It is difficult for the tester to determine whether the solution has reached room temperature. Therefore, there is an urgent need for a solution storage bottle that is easy to use, prevents contamination and can show temperature. UTILITY MODEL CONTENT
