Let’s Dive into Nalge Nunc Oak Ridge Centrifuge Tubes, Polypropylene Copolymer, NALGENE 3139-0030, Pack of 10

The Nalge Nunc Oak Ridge Centrifuge Tubes, Polypropylene Copolymer, NALGENE 3139-0030, Pack of 10 are designed for demanding laboratory applications, specifically those requiring high-speed centrifugation and chemical resistance. These tubes, manufactured by Nalge Nunc, are constructed from polypropylene copolymer, known for its robustness and inertness. Their key features include a 30mL nominal volume (32mL actual), autoclavability, and the ability to withstand up to 50,000 g in refrigerated centrifuges, making them a staple in many research and clinical settings.

I encountered a critical need for these tubes when our existing polycarbonate centrifuge tubes began showing signs of degradation after repeated autoclaving. We needed a reliable, chemically resistant, and autoclavable solution for preparing samples for protein precipitation and nucleic acid extraction. The listed chemical resistance and high g-force rating of the Nalge Nunc Oak Ridge Centrifuge Tubes, Polypropylene Copolymer, NALGENE 3139-0030, Pack of 10 made them an appealing choice.

Upon unboxing, the tubes felt sturdy and well-made, with a contact-clear finish that allowed for easy visual inspection of the contents. The polypropylene screw closures appeared robust, providing a tight seal. My initial assessment was positive, but the true test would be their performance in the centrifuge and their resistance to harsh solvents.

I was also considering Corning’s polypropylene centrifuge tubes and Eppendorf’s conical tubes. However, the Nalge Nunc tubes stood out due to their specific geometry optimized for Oak Ridge rotors and their stated superior chemical resistance compared to polycarbonate options we previously used. The price point, while higher, seemed justified given the promised durability and reliability.

My first impression was one of cautious optimism. The build quality seemed excellent, and the specifications aligned perfectly with our laboratory’s needs. Now, it was time to put them through their paces.
