Natural HDPE Wide Mouth Round Bottles are ideal for general lab use with solids and powders. These HDPE bottles provide an excellent moisture barrier and are impact resistant. They are ideal for high-speed filling, demanding pharmaceutical specifications and the rough handling of interstate shipping.

Attached black phenolic (thermoset) caps with Polyseal™ cone 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.
