Made of paraffin and plastic polymers, these 3 Ameriplast paraffins deliver excellent processing and yield thin, flat, and wrinkle-free sections. They were developed to meet the demanding and versatile needs of a laboratory. Paraffin #T8331 contains dimethyl sulfoxide to improve infiltration rate. Paraffin #T8332 consists of a blend of low molecular-weight paraffin and polymers to reduce melting point, which protects tissues from excessive temperature during processing. All paraffin is supplied in 1-kg bags.
