Plastic pasteur pipette is made of selected medical grade LDPE raw material, is a kind of experimental consumables in laboratory, food research, medicine and other industries. It has the advantages of low cost and easy to use, and is suitable for the absorption and transfer of small amounts of liquid. It has a certain degree of elasticity and plasticity, can be bent at a certain angle, which is conducive to entering the micro-cargo anisotropic containers for the extraction or addition of liquid and other operations. Good transparency, easy to observe. Good elasticity, not easy to break, suitable for rapid pipetting. Easy to use, accurate and reliable, with good repeatability of drop volume.
Usage:
1. When using the plastic dropper, pinch the top with your fingers to drive out the air in the dropper, then stick the dropper into the reagent bottle and release your fingers, the reagent will be inhaled.
2. After taking the liquid dropper should keep the big belly that head on the top, do not flat or inverted, to prevent the solution backflow and corrosion of the rubber head.
3. When dropping liquid, it should be placed above the beaker in the air, do not touch the wall of the beaker, so as not to stain the burette or cause contamination of the reagent.
4. Do not place the dropper on the test bench or elsewhere to avoid staining the dropper.
5. It is strictly prohibited to take up another reagent with an unwashed dropper (do not rinse the dropper on the dropper bottle with water).
