Wide Mouth Rounds 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 thermoset (phenolic) 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.
