Dropper
Whatsapp Order
A Dropper is a small laboratory tool used to transfer precise volumes of liquids in drops. Typically composed of a glass or plastic tube with a squeezable rubber bulb at one end, the dropper allows controlled dispensing of liquids for experiments, titrations, or sample preparations. Its simple design enables easy handling and measurement of small quantities, making it indispensable in chemical, biological, pharmaceutical, and educational laboratories. Droppers are ideal for adding reagents dropwise, conducting qualitative tests, or transferring liquids without contamination.
