LEICA Biosystems EM-400 Embedding Medium Paraffin

EM-400 Embedding Medium is a blend of purified paraffin with synthetic polymers that enables sectioning with minimal compression. The medium can facilitate routine sectioning at 1-2 microns on a rotary microtome. Its low melting point (56-57º C, water bath temperature 37-42º C) reduces potential artifactual distortion in tissues heated above 60º during paraffin impregnation. EM-400 will remain stable even at elevated temperatures.
