These centrifuge bottles, molded from transparent polypropylene, are designed for aseptic fluid transfer and sampling in biopharmaceutical applications. Ideal for large-volume processes such as cell harvesting, pelleting, and protein purification, the bottles offer high clarity and excellent mechanical strength. Made from autoclavable polypropylene (PP), they are suitable for moderate-speed centrifugation of both biological and chemical samples. The rigid bottle body ensures stability during centrifugation, while the seal cap features an extended lip for easy removal from centrifuge rotors and textured ridges for secure handling during opening and closing.
