Natural LDPE Boston Round Bottles are the perfect solution for liquid sample handling in a squeezable bottle. These bottles are virtually unbreakable and more resistant to stress cracking than HDPE bottles. They retain their impact strength at very low temperatures.
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.
