A support matrix or form of embedding medium for frozen sectioning. This medium freezes quickly supporting the tissue for sectioning at 3 μ and up with no cracking of the matrix at temperatures from –8 to –25 °C.

• Coloured PolyFreeze makes differentiating multiple specimens easy during sectioning and staining
• Experience less curling, less ice artifacts, faster freezing with PolyFreeze

Snap freeze using PolyFreeze with isopentane and liquid nitrogen or dry ice (slush/slurry or bunker). Store specimens frozen in PolyFreeze in liquid nitrogen canisters or in airtight containers in a –80 °C freezer.
