Polyfin is a mixture of highly refined paraffins and co-polymer alloys in a convenient wax pellet. This unique formulation provides optimal tissue support while maintaining exceptional clarity. Our Polyfin™ has been institutionally tested and found to function flawlessly in pressure/vacuum fluid flow processors. Its low melting point (55°C) eliminates any tissue distortion caused by excessive heat during processing. In a recent study conducted by a Medical Center Histologist, monitored by a CPA firm using standard blind protocols, POLYFIN™ clearly demonstrated the least compression of seven popular paraffins.
