Combines highly refined paraffin that has narrow carbon-chain distribution with polymers to provide minimal compression and ultrathin sections. Quality ribbons of flat, thin sections highlight morphological detail. Ameraffin® medium can be used for both embedding and infiltrating. It can also be substituted for an existing embedding medium with little or no change in methodology. An antioxidant has been added to help prevent discoloration and inhibit stain fading. Melts uniformly from 131°F–134.6°F (55°C to 57°C).
