Abstract
A sealed bowl rotor having a transparent lid for easy visual checking of rotor contents. The lid has sealing means that automatically creates a seal which prevents the escape of liquid samples from within the rotor when the lid is placed on the rotor. The rotor design prevents the application of any possible hydraulic loading on the transparent lid. The installing/removing mechanism on the lid provides the capability for removal of the lid after the centrifugation run without disturbing the contents of the samples within the rotor.
