Advantage
1. The volumetric flask is made of polypropylene, which does not break like glass and can be reused for a long time, with excellent chemical resistance and durability.
2. The bottle mouth has a polypropylene stopper to reduce evaporation and prevent liquid leakage. The long neck shape is convenient for holding and shaking to mix liquid.
3. The transparent bottle body and accurate blue graduation line ensure the accuracy of your experiments.

Instruction
When pouring liquid, use a glass rod to slowly transfer the solution, when the liquid is close to the scale line, you can use a dropper to drip slowly until the liquid concave surface reaches the scale line, tighten the stopper of the bottle and shake moderately to mix the liquid evenly

Note: When mixing liquids, make sure the cap is tightly closed. When you finish using the volumetric flask, please remember to clean it and ensure it is dry after cleaning.
