A unique aerosol designed to rapidly cool any material. Cyto-Freeze™ is the fastest coolant available. Excellent for cooling liquid, semi-solid, and solid samples. 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 ‚Äì60°F (‚Äì50° C) in three seconds. To cut sections, simply mount tissue directly on a microtome holder, spray, and section. 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 (Environmental Protection Agency) designated substitute for ozone-depleting HFCs and CFCs (chlorofluorocarbons). The pure formulation and unique valve provide superior chilling properties. Chills faster, uses less refrigerant, and maintains lower temperatures than products that use inexpensive filler material. Only Cyto-Freeze™ is 100% triple filtered pure liquid gas. Cheaper sprays use nonfiltered material, which reduces cooling ability, adds contaminants, and injects moisture- containing crystalline artifacts. Can contains eleven ounces of non- corrosive, non-flammable, odorless, and completely volatile gas.
