Medical Grade Printing

Our 20-400  Black Graduated Bulb Glass Medical Dropper is a continuous thread (CT) polypropylene dropper. Above all, our printed glass pipette includes baked graduation marks at .25, .5, .75, and 1 mL. This baked-in printing is lead-free and made to withstand summers in corrosive chemicals.

The benefit of this new ink is it uses a printing method called “permeation.” Whereas black ink is done via silk screen printing which can “react” with certain products, Our new permeated ink has been lab-tested & has been proven to be Non-reactive. 

The tip of the glass features a bulb-round tip, The main difference between a straight-tip pipette and a bulb-tip pipette is. A bulb tip pipette is used for precise drops, withholding any spillage of product solution. This a task that a straight-tip pipette struggles with as it is used to deliver a larger output in one stroke.

Silicone Bulb

In addition, Our 20-400 oz black graduated bulb glass dropper includes a large silicone bulb. This increases the dispensing power to our 76mm straight-tip graduated glass pipette between 0.5 mL – 1.0 mL of liquid per stroke. This makes our black graduated bulb glass dropper a perfect closure for precise dispensing. 

For instance, it is great for a variety of uses from aromatherapy and essential oils.
