Centrifuge Bottles

• Available with standard caps for low-speed work and sealing caps for high-speed applications - sealing caps have a built-in gripper to facilitate removal from the rotor
• Extra thick walls for durability-resistant to most chemicals
• Wide mouth design makes filling and decanting easier
• Molded in graduations
• Frosted area facilitates writing on the bottle

These precision molded centrifuge bottles are available in polycarbonate or polypropylene. For low speed applications the bottles provide excellent value for large volume/large batch centrifugation procedures. For high-speed work, the easy-to-use polypropylene sealing caps with silicone O-rings enable leak-free processing at high centrifugal forces over long durations. Bottles must be filled to 80% of capacity. Centrifuge bottles may be autoclaved at 121°C (248°F) at 15 psi for 20 minutes. Caps should be placed on the bottles without engaging the threads. Bottles are qualified to the rated g-forces using Sorvall¨ and Fiberlight¨ high-speed rotors, tested at 20°C (65°F), with bottles filled to 80% of capacity.

Failure to use the correct rotor cushion or adapter will shorten the life of the bottle and may prevent achievement of the maximum rated RCF and/or bottle failure.

Prolonged autoclaving and reuse may cause stress cracks, crazing or bottle discoloration.
