50ml Non - Graduated External Thread High-Speed Centrifuge Tube

Compatibility is critical for safety. You must: Consult your centrifuge and rotor user manual for the list of certified tubes and maximum allowed speeds (RPM/RCF) for each tube-adapter combination. Match the tube's stated maximum RCF rating to your protocol, ensuring you do not exceed it. Use the correct adapter or spacer specified by the rotor manufacturer for the tube size you are using.

For high-speed use, a screw cap with a sealing ring (O-ring or cone seal) is essential. This creates a pressure-tight seal to prevent leakage, aerosol generation, and sample loss under high G-forces. Snap caps are generally not suitable for high-speed applications.

Always perform a visual and tactile inspection: Visually: Check for scratches, cracks, cloudiness, or deformities. Tactile: Ensure the tube is not brittle and the cap threads/seal are intact. Retire immediately: Any tube showing signs of wear or damage must be discarded, as imperfections can become failure points under stress.

For safety and performance, tubes should typically be filled to 70-80% of their nominal capacity unless the rotor manual specifies otherwise. Underfilling can cause tube collapse under high vacuum (in ultracentrifuges), while overfilling increases stress on the tube seal and walls.
