First Claim
1. Apparatus for processing and embedding tissue samples comprisingrotor means having a rotational axis and a plurality of well means outward of its rotational axis for holding tissue samples,means to successively supply processing liquids and liquid embedding material to said well means,means to intermittently rotate said rotor means at a sufficient speed to slough liquid from said well means, andwell cover means which retain said tissue samples in said well means while accessing processing liquids and embedding liquids to said well means, said well cover means comprising a peripheral frame defining a fluid passage opening and a porous mesh spanning said opening.

Abstract
Tissue samples are prepared for embedding and then embedded within wells of an intermittently rotatable rotor. After each successive liquid is supplied to the sample wells, the rotor is spun in order to slough off liquid from the samples. The sloughed liquid is collected by an outer shroud. The shroud is preferably made fluid tight so that the interior region of the shroud can be communicated to vacuum to force embedding material into the interstices of the tissue samples.

13. Apparatus for processing and embedding tissue samples comprising
rotor means having a rotational axis and a plurality of well means outward of its rotational axis for holding tissue samples, means to successively supply processing liquids and liquified embedding material to said well means, means to intermittently rotate said rotor means at a sufficient speed to slough liquid from said well means, and well cover means which retain said tissue samples in said well means while accessing processing liquids and embedding liquids to said well means, said well cover means comprising a peripheral frame defining a fluid passage opening and a porous mesh spanning said opening below an upper surface of said peripheral frame providing a region for embedding material above said mesh, whereby when liquified embedding material solidifies, said mesh is embedded therein and said cover is attached to said solidified embedding material.
