Scienceware® Polystop™ Glass Dropper Bottles
The Polystop™ Dropper Bottle provides a distinct and clever advantage over other glass dropper bottles. The dropper section easily pulls free for use while the polypropylene stopper remains snugly in the neck of the bottle. The clear glass bottle has a ground neck, and the dropper has a soft bulb. Disassembles for easy cleaning.
