How to get a stuck tube out of the centrifuge rotor...

To remove a tube when using swinging buckets, remove any tube cap or closure and tube contents. Always invert the buckets when putting them into an autoclave. Autoclave the rotor at 250 degrees Fahrenheit, for 15 minutes at fast exhaust. The tubes or bottles should loosen or soften enough to slide out.

If it is a fixed angle rotor - uncap, vent, and empty the tube; invert the rotor over a clean wash basin, if necessary, with the lid off, and put the rotor into an autoclave. Use the same autoclave cycle as with swinging bucket rotors.


Important Note: You should NEVER try to remove a tube with a sharp object. If a spacer or cap is stuck, DO NOT autoclave; try applying dry ice to the cap or spacer.
