Diamond RealSeal™ Amber Square Plastic Laboratory Bottles from Globe Scientific meet the requirements of the most demanding applications. These new additions to the Diamond RealSeal offering expand the range with a selection of bottles that store and pack more efficiently than standard round bottles. 

Like the rest of the Diamond RealSeal line, these new bottles are precision molded from virgin resins for consistent wall thickness and smooth interior and exterior surfaces. The bottles include leak-proof polypropylene caps that are engineered with an integrated seal ring for leak-proof closure.

These amber square bottles store and pack efficiently to maximize space utilization. The wide mouths are perfect for sample collection and facilitate the rapid filling and emptying of solids, powders, and viscous liquids.

Diamond RealSeal Leak Testing Protocol

  • Bottles are filled to 80% of nominal capacity, closed per minimum torque requirement

NOTE: This test protocol applies more than 5x the pressure used by competitors to claim “leak proof” closures.
Standard leak testing of Diamond RealSeal™ bottles is performed with water. Testing with other liquids may yield different results.
