CellPro™ Oak Ridge High-Speed Polypropylene (PP) Centrifuge Tubes are engineered for rigorous laboratory applications where exceptional chemical resistance and durability are paramount. Though not as transparent as their polycarbonate counterparts, these tubes deliver consistent, reliable performanceeven through repeated autoclave cycles. Superior Chemical Resistance: Built to withstand a broad spectrum of lab reagents without compromise. Long-Lasting Durability: Designed for repeated autoclaving with minimal degradation in performance. High-Speed Capability: When paired with a CellPro™ sealing cap (sold separately), both 30mL and 50mL tubes meet the demands of high-speed centrifugation. Secure Sealing: Equipped with polypropylene linerless closures that are easy to clean and provide leakproof protection under normal conditions. Optimal Usage: For best performance, ensure the tubes are filled to at least 80% of their capacity.
