Liquid nitrogen is a colorless, odorless, tasteless liquid, with a boiling point of -195.79 C -320 F. Liquid nitrogen can cause rapid freezing on contact with living tissue, and can result in serious injuries if exposed to the skin or eyes. Beyond injury through contact exposure, rapid boiling of liquid results in nitrogen gas production.

Liquid Nitrogen Cooling Plastic Pulverizer. Liquid nitrogen Cooling Plastic Pulverizer, also known as freezer milling, freezer grinding, and Freezing Pulverizer is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy
Overview. The BioPulverizer reduces tissue hard-frozen in liquid nitrogen to a fine powder. Because of the high water content, most fresh tissue becomes as brittle as glass at liquid nitrogen temperatures. A sharp blow with a hammer will shatter it into tiny pieces. Called freeze-fracturing or cryopulverization, the method is especially useful for preparing tough, fibrous

Apr 04, 2021 Crypulverization, in simple terms, relies on the fact that frozen water is brittle at liquid nitrogen temperatures. Therefore, drier samples such as seeds, bark or skin are very difficult to disrupt. For these tissues we recommend using the Cellcrusher in conjunction with the Drill-bit accessory. This accessory fits into any household drill and will result in tissue pulverization

Sep 28, 2016 After a liquid nitrogen treatment, the lump, wart or whatever is being treated will gradually discolour and fall off. The surrounding skin will sometimes become red and swollen and be sore for a day or so. It is similar to a mild burn. Occasionally a blister sometimes a blood blister forms. If this happens, it is best to pop it with a clean ...
Liquid nitrogen expands 695 times in volume when it vaporizes and has no warning properties such as odor or color. Hence, if sufficient liquid nitrogen is vaporized so as to reduce the oxygen percentage to below 19.5, there is a risk of oxygen deficiency which may cause unconsciousness. Death may result if oxygen deficiency is extreme.
