If you’re looking for a reliable, accurate, and durable tool for small-volume liquid handling in laboratories, schools, home chemistry, industrial testing, or DIY crafting, the graduated glass dropper with rubber bulb is your ideal solution. Designed by Huida Laboratory Consumables, this high-quality lab pipette combines premium borosilicate glass construction and strong latex suction bulbs to deliver consistent, precise liquid extraction and dispensing for all your daily experimental needs.

Our rubber bulb graduated pipette is built to outperform standard cheap droppers. The glass tube features laser-etched, crystal-clear permanent markings, ensuring you can read measurements from 0.5ml up to 10ml with absolute accuracy, eliminating measurement errors during chemical reagent transfers, essential oil blending, ink filling, or solution titration. The long, slender glass body allows easy access into narrow-mouth bottles, beakers, test tubes and flasks, while the fine tapered tip controls liquid drop size perfectly for slow, controlled dripping.

What sets this lab dropper apart is its upgraded suction bulb design. Smaller specifications (0.5ml-3ml) come with a flexible red latex suction head, while larger 5ml and 10ml options use an extended, thickened blue rubber bulb. The lengthened rubber cap greatly boosts internal suction force, preventing accidental liquid backflow and slipping, even when handling thicker liquids. The soft, elastic rubber head fits tightly onto the glass tube, will not crack, harden or leak after repeated squeezing, alcohol cleaning and long-term frequent use.

Made of high-transparency, corrosion-resistant premium glass, these glass pipette droppers withstand most common acids, alkalis and lab solvents, and can be easily cleaned and reused hundreds of times, far more eco-friendly and cost-effective than disposable plastic droppers. All products are manufactured and calibrated at standard 20℃ laboratory temperature, meeting general laboratory grade precision requirements.

This versatile graduated dropper fits a wide range of application scenarios: professional scientific laboratories, school chemistry teaching experiments, biology labs, medical inspection, cosmetic essential oil making, e-liquid mixing, aquarium water testing, ink transfer, gardening nutrient dosing, and home DIY craft projects. Available in a complete size lineup: 0.5ml, 1ml, 2ml, 3ml, 5ml, 10ml, you can always pick the exact capacity you need for your specific task.

When quality, precision and durability matter for your liquid handling work, Huida’s glass graduated dropper with rubber bulb is the trustworthy choice for every lab technician, teacher, student and hobbyist.
