Real-World Testing: Putting Beckman Coulter Polycarbonate Thickwall Tube, 3.5ML, Pack of 25, Beckman Coulter 349622 to the Test
First Use Experience
My initial testing involved separating protein lysates using a Beckman Coulter Optima XE-90 ultracentrifuge. The tubes were subjected to forces exceeding 100,000 x g for several hours. The tubes exhibited excellent resistance to deformation and leakage, even under these extreme conditions.
I also tested the tubes at varying temperatures, ranging from 4°C to 37°C, to simulate different experimental conditions. The polycarbonate material remained stable, exhibiting no signs of cracking or embrittlement. Furthermore, cleaning was a breeze, as the smooth interior surface prevented sample adhesion, allowing for efficient and thorough decontamination.
Extended Use & Reliability
After months of rigorous use, the Beckman Coulter Polycarbonate Thickwall Tubes have proven to be remarkably reliable. There have been no instances of tube failure or leakage, even after repeated use and sterilization cycles. The tubes have shown negligible wear and tear, testament to the high-quality polycarbonate material used in their construction.
Compared to our previous experiences with less robust tubes, these have been a game-changer. Our centrifuge results are now consistent and reliable, leading to more accurate and reproducible scientific findings. The tubes have significantly outperformed our previous tubes, saving us both time and resources.
