18mm 20mm 24mm 28mm Silicone Bulb Gold Silver Smooth Matt Closure Plastic Dropper for Essential Oil
Plastic Dropper: A Versatile Dispensing Tool
A plastic dropper is a simple yet indispensable tool for precise liquid handling and transfer. Typically made from polyethylene (PE) or polypropylene (PP), it consists of a flexible, squeezable bulb attached to a narrow, graduated tube.
Its operation is based on air pressure control. Squeezing the bulb expels air; releasing it creates a vacuum that draws liquid up into the tube via capillary action. A second squeeze then dispenses the liquid drop-by-drop with high accuracy. The graduated markings on the tube allow for approximate volume measurement.
Key advantages include chemical resistance, disposability, cost-effectiveness, and user safety by minimizing direct contact. Modern designs often feature long, fine tips for enhanced precision and leak-proof seals.
Widely used across industries, its applications range from administering medication and essential oils in pharmaceuticals and aromatherapy to adding reagents in laboratories, blending pigments in arts, and formulating small batches in DIY cosmetics and e-liquids.
