Thermo Scientific Centrifuge Lid O-ring Kit

The Thermo Scientific (Fiberlite) F13S-14X50CY O-ring Kit is a critical maintenance set designed specifically for the Fiberlite F13S-14 x 50mL carbon fiber fixed-angle rotor. Because this rotor is engineered for high-speed centrifugation (often exceeding 13,000 RPM), it relies on a sophisticated sealing system to maintain biocontainment and prevent aerosolization of samples during a run. This kit contains the precision-engineered elastomeric seals - including the primary lid O-ring and the smaller central post O-ring -required to ensure the rotor remains vacuum-tight and leak-proof.

Over time, these O-rings can undergo "compression set" or develop microscopic cracks due to repeated exposure to centrifugal stress, temperature fluctuations, and chemical vapors from solvents or disinfectants. A compromised O-ring not only risks sample loss but can also lead to a loss of vacuum in the centrifuge chamber, which causes the motor to work harder and may lead to an over-temperature error. This kit allows lab technicians to perform routine preventative maintenance by replacing worn seals, thereby ensuring the rotor meets its original safety and performance specifications. The O-rings are typically manufactured from a chemical-resistant synthetic rubber, such as EPDM or Viton, to withstand the harsh environment of a high-speed centrifuge.
