Biological centrifuge bottles are essential laboratory consumables designed for the safe and efficient separation of biological samples in centrifuges. These bottles are typically made from durable materials like polypropylene (PP) or polycarbonate (PC), offering chemical resistance and high-speed compatibility. Common features include leak-proof caps, graduated markings for precise volume measurement, and sterilization compatibility (autoclavable or gamma-irradiated). They come in various sizes (e.g., 15mL, 50mL, 250mL) and styles (conical, round-bottom). Key products in this category include high-speed centrifuge bottles, sterile conical tubes, and cryogenic storage bottles. Applications range from cell culture preparation to DNA/RNA isolation in life sciences, pharmaceuticals, and clinical research.
