KRYOS SAFETY PRECAUTIONS FOR LIQUID NITROGEN Nitrogen is an inert, colorless, odorless, and tasteless gas making up four-fifths of the air you breathe – and can be very dangerous. Air is roughly one-fifth oxygen. Liquid nitrogen is at a temperature of -196°C (-320°F) under normal atmospheric pressure. Extreme Cold - Cover Eyes and Exposed Skin Accidental contact of liquid nitrogen or cold issuing gas with the skin or eyes may cause a freezing injury similar to frostbite.
OS KRYOS GENERAL INFORMATION GENERAL INFORMATION The KRYOS Controller canand monitor and control both nitrogen the liquidlevel nitrogen The KRYOS Controller can monitor control both the liquid and level and vapor temperature range in the cryostorage unit selected. you haveKRYOS selected.
