This moisture-free freeze spray is used to “flash freeze” tissue specimens in the cryostat or harden difficult-to-cut tissue on the microtome during sectioning. The variable pressure trigger and capillary nozzle enables precise cooling or freezing of tissue and helps prevent over-cooling of specimen. Environmentally friendly formulation does not contain any chlorofluorocarbons (CFCs) or hydroflourocarbons (HFCs).
Impact to the environment
•Global Warming Potential (GWP)—measure of a gas’s ability to absorb/re-emit infrared radiation over time*
•Today’s formulation has a smaller Global Warming Potential footprint than the previous freeze spray formulation
