It looks as though it should be used for administering laudanum! A 30mL, 1-1/4" sq x 3" tall clear glass bottle, it has thick molded sides and a heavy lip: very antique in appearance. It is stoppered with a red(!) rubber stopper which is the squeeze bulb for the glass dropper tube inside. A real eye catcher, but give it a good wash please. It clearly is not sterile.

Eye dropper, tongue dropper, test tube dropper, petri dish dropper, anywhere dropper. Use this 3" glass dropper, with a rubber squeeze bulb to drop small amounts of liquid wherever you think they should go. You will have to measure by counting drops, though, because there are no markings on it. Also, it is called "3" because that is about how long the glass tube is. Overall, it is 4" long.

These blue glass dropper bottles are the color of the cold cream bottles that everybody's mother used when everybody's mother used cold cream. Measure 3-1/8" tall x 1-15/16" dia and hold (1) oz. Plastic safety dropper cap is 2-3/8" tall and marked at 0.4 and 0.8ml.

We’ve never had a bottle quite this one, in spring-like translucent-green coated glass. Plus it’s a dropper bottle, and the rubber bulb matches the pretty green color. Holds 10ml (1/3 oz), and measures 2-5/8” tall x 1” dia with a 7/16" ID mouth. Has a black plastic cap, and the 2” long glass dropper has a 1/16” ID tip.

Bottle-less glass eye-droppers. Measure 2-3/4" long with a rubber bulb and a screw cap, and the dropper will pop out of the cap if you need it to. Hold about 1ml each. We’re thinking student lab supplies, paper and fabric art applications, really careful baking uses (too much green food coloring makes the cookies look horrid), and homemade tincture-dosing.
