The basics The needle tip syringe has a threaded removable tapered tip which can be unscrewed and removed in order to add other specialized nozzles. The benefits The syringes do not leak and the plungers glide smoothly to prevent accidental discharge. The uses Use them to precisely transfer fluids from large to small containers, even those with narrow openings, and quickly measure paints for mixtures without losing material. Artists even use Jacquard syringes to apply mediums, such as resists, paints and dyes, directly to fabric, canvas and paper.
