4oz (120ml) Am Boston Rnd w/ 22-400 Blk Phenolic

Amber Boston Round Bottles protect contents from UV rays and are ideal for light sensitive products. These general use bottles are perfect for liquids. They feature a round body, rounded shoulders and narrow screw neck opening. These environmentally sensitive bottles help eliminate waste and help to insure product integrity for long term storage.

Attached black phenolic (thermoset) caps with PolyCone liners form an exceptionally tight seal and offer a good chemical barrier. This liner molds itself around the sealing areas of the finish as the cap is screwed on, virtually eliminating leakage, evaporation, contamination, binding and backing off. Great for everything from liquids, to soaps, to macro-invertebrates.
