Abstract: The present invention is concerned wit analytical equipment comprising a centrifuge and means for introducing and/or withdrawing from the centrifuge, a carrier for liquid materials to be centrifuged in preparation for testing. The centrifuge comprises a plurality of swing supports, such as buckets or baskets, for holders or carriers of the liquids to be centrifuged, and counterweight or balancing means for assuring balanced operation even though one or more of the swing supports is or are empty while others are loaded with carriers. Provision is also made to avoid the necessity to lower a carrier for the material to be centrifuged into the centrifuge and later lifting it out. Instead, the material is supplied and discharged in a horizontal path, avoiding the lowering and lifting. When a protective cover or casing is provided, "windows" may be made adjacent the swing supports therein to permit such transfer into and out of the centrifuge, and in a preferred embodiment, the swing supports carry curtains for closing the windows automatically during operation.
