Abstract: An apparatus and method to simplify and accelerate the transfer of tissue biopsy samples from fixative to automatic tissue processing cassettes comprises a strainer device and a preformed filter. The strainer device is constructed from a perforated material such as stainless steel screen and is substantially conical in shape. The device is provided with a support ring attached to an upper edge of the cone; the ring is designed for positioning the device on a fixative collection container and for attaching a convenient handle. The tip of the cone is truncated, providing a planar collection surface. A preformed filter, also of conical shape with a flattened tip matching the collection surface, is inserted into the strainer device. Fixative, containing tissue biopsy samples, is poured into the device, and the samples rest on the flat bottom and sides near the bottom while the fixative flows through into the fixative collection container.
