Silicone Kubber Multiple Molds for Paraffin Embedding

It is frequently desirable, when embedding specimens in paraffin, to take them through the procedure in groups rather than singly. Ackerman (1958) has described a multiple plastic mold which may be used for this purpose, while Adel-son and Schatz (1957) have recommended the use of plastic ice-cube trays. With the first of these there is the advantage that the size and number of compartments can be adjusted to the experimental requirements; with the second, the removal of the hardened blocks from the tray is much more convenient.
