A unique aerosol designed to rapidly cool any material. Use for ultra-rapid freezing of fresh tissue, cooling of liquids to force precipitates prior to filtration, and chilling of field samples. During cryostat sectioning, Cyto-Freeze flash-freezes tissues instantly. It cools to -60°F in three seconds. Saves time and eliminates water crystals caused by slower freezing methods. The supplied five-inch, polyethylene "snorkel" pinpoints freezing power exactly where needed. A trigger actuator valve provides controlled delivery. Contains an EPA designated substitute for ozone-depleting HFCs and CFCs. Cyto-Freeze is 100% triple-filtered pure gas. Sold in a case of 6. Each case come with a 3 foot snorkel for access to difficult to reach areas.
