Plastic Dropper Product Description

Material & Application

The plastic dropper is made of PE (polyethylene) material, serving as a common consumable for laboratory, food research, pharmaceutical and other industries.

Usage Instructions

1. When using the plastic dropper, squeeze the top tightly with fingers to expel air from the dropper, then insert the dropper into the reagent bottle and release your fingers to draw in the reagent.
2. After drawing liquid, keep the bulb end of the dropper facing upward. Do not lay it flat or invert it to prevent backflow of solution that may corrode the rubber head.
3. When adding liquid, hold the dropper suspended above the beaker without touching the wall, to avoid contaminating the dropper or the reagent.
4. Rinse the used dropper thoroughly with clean water immediately for reuse.
5. Never use an unwashed dropper to draw other reagents.
