摘要
An apparatus and method for preserving cytological specimens for histological or histopathological use. A cytological sample from a biological tissue such as a tumor or a tumor cell line is dehydrated, disbursed and evenly distributed throughout a volume of molten material. The molten material is then drawn into a tubular member such as a pipette and allowed to solidify. Upon solidification, the cylindrical specimen is partially or completely extrudedfrom the tube for further processing, including fixation, dehydration and molten paraffin infiltration and embedding as required for presentation to a sectioning device such as a microtome. Thin circular slices of the cylindrical specimen are removed from the cylindrical specimen and transferred to a slide, fixed and stained as desired. The device and method enable the production of a slide bearing a spatially homogeneous distribution of cytological material for microscopic examination.
