These 150ml syringes are individually sealed for cleanliness and safety, making them ideal for measuring and dispensing essential oils, inks, solvents, adhesives, and other fluids. The clear, well-printed gradation marks remain legible through repeated use and washing. Each syringe features a smooth-gliding plunger with a tight-sealing rubber tip to ensure precise control and leak-free operation. The plunger can be fully removed, and the rubber seal detached, allowing for thorough cleaning between uses.
