Laboratory Glass Dropper with Rubber Bulb for Reagent Dispensing

The Laboratory Glass Dropper with Rubber Bulb is a simple liquid-handling tool designed for transferring and dispensing small quantities of reagents, solutions and samples drop by drop. It consists of a transparent glass tube with a tapered dispensing tip and a flexible rubber bulb. Compressing and releasing the bulb creates suction to draw liquid into the glass tube; gentle pressure then enables controlled dropwise dispensing. Glass droppers with removable rubber bulbs are commonly reusable and easier to clean. The dropper is particularly useful during titration-related procedures, such as adding an indicator or making very small reagent additions near an endpoint. It is also suitable for qualitative analysis, microscopy, sample preparation and routine reagent transfer.
