How to find the right Lab Centrifuge Bottles AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Lab Centrifuge Bottles
- Rotor compatibility
- Match the bottle volume and dimensions to the rotor or adapter your centrifuge maker lists A bottle that is nominally the right volume but has the wrong dimensions can fail or unbalance the rotor.
- RCF rating
- The bottle's maximum rated RCF must exceed your run's RCF Running a bottle above its rating risks cracking and sample loss.
- Material
- Polycarbonate for clarity; PP or PPCO for chemical resistance and repeated autoclaving Polycarbonate crazes with alkaline detergents and repeated autoclaving.
- Fill level
- Fill to the manufacturer's minimum volume for high-speed runs Underfilled bottles can collapse or deform under high g-force.
- Sealing
- Use sealing caps or closures for biohazards and volatile samples Aerosols can escape from standard caps during the spin.
Brands that matter
- Thermo Scientific Nalgene: Broad range of PC, PP and PPCO centrifuge bottles.
- Beckman Coulter: Bottles designed for its own rotors.
- Thermo Scientific Sorvall: Bottles matched to Sorvall rotors.
- Corning: Conical and large-volume PP centrifuge bottles.
- Eppendorf: Bottles and adapters for its own centrifuges.
What to avoid
- Bottles with no stated RCF rating
- Washing polycarbonate bottles with alkaline detergents
- Bottles past the manufacturer's cycle or age limits, or with visible crazing
