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.
Above all, the 76 mm graduated straight tip glass pipette with dropper has graduation marks at .25, .5, .75, and 1 mL baked into the pipette which holds up to the most corrosive solutions.

Long Monprene Bulb

In addition, our 1 oz Black Medical Grade Child Resistant Graduated Glass Dropper has a dispensing output between 0.5 mL – 1.0 mL of liquid per stroke. This item has a 20-400 neck finish. For instance, the first number refers to the diameter (in mm), and the second refers to the closure depth, style, and thread.
