    Time:2016-08-30Publisher:Xingyuan

    Plastic droppers are made of materials such as PE and PET, and are a type of experimental consumable in industries such as laboratories, food research, and pharmaceuticals. It has the advantages of low cost and simple use

    There are specifications such as 0.2ml, 0.5ml, 1ml, 3ml, 5ml, 10ml, etc

    Usage:

    1. When using a plastic dropper, pinch the top with your fingers, expel the air from the dropper, then insert the dropper into the reagent bottle, release your fingers, and the reagent will be sucked in.

    2. After taking the liquid, the dropper should keep the big belly end above and not be placed flat or upside down to prevent the solution from flowing back and corroding the rubber head

    3. When adding liquid dropwise, it should be suspended above the beaker and not in contact with the beaker wall to avoid contaminating the dropper or causing contamination of the reagent

    4. Do not place the dropper on the test bench or other places to avoid contaminating the dropper

    5. The used dropper should be immediately rinsed with clean water for reuse

    6. It is strictly prohibited to use an uncleaned dropper to aspirate other reagents (do not rinse the dropper on the dropper bottle with water)
