ABSTRACT:
The present invention is directed to a transparent safety cover for sealing the mouth of a pivotally mounted bucket of a centrifuge rotor. The cover has a first surface configured to make telescoping engagement with the sidewall of the rotor bucket. A shoulder adjacent the first surface abuts the top of the bucket to limit the length of engagement. The first surface has an annular groove containing a resilient O-ring which makes a seal between the cover and the bucket. In the upper portion of the cover, there is a raised dome-like structure with a circular aperture at the top. The aperture has inverted conical walls and is sealed by a movable, resilient, sealing plug. The plug has a tapered body and at the lower portion thereof, are wall gripping means for retaining the plug in a raised, unseated, position. With the plug in the unseated position, the bucket is vented to the atmosphere permitting telescoping movement of the cover with respect to the bucket. Additional means are provided to block inadvertent withdrawal of the plug from the aperture.
