They consist of a long, slender tube with a tapered tip at one end for drawing up and dispensing liquids. The other end typically has a bulb or pipette filler for controlling the aspiration and dispensing of the liquid.
Lab droppers come in various sizes and designs, including disposable plastic droppers and reusable glass pipettes. They are widely used in chemistry, biology, medicine, and other scientific disciplines for tasks such as measuring reagents, adding precise volumes of solutions to experiments, and performing titrations.
The design of lab droppers allows for accurate and controlled dispensing of liquids, making them essential tools for laboratory work where precise measurements are necessary. They are also often used in conjunction with other equipment, such as microscopes or spectrophotometers, for various analytical procedures.
