Liquid nitrogen

Because the microscope uses a cooled detector, you need a supply of liquid nitrogen to cool the detector element.



Avoid hazard

The gas boiling off liquid nitrogen can create an oxygen deficient environment in an insufficiently ventilated room.



Avoid hazard

Be careful not to contact the liquid nitrogen with your skin. It is extremely cold. Exposure may cause burns. Wear protective gloves and goggles and follow
standard laboratory safety practices. When filling a vacuum bottle or the dewar, pour slowly. Pouring too quickly can cause the bottle or dewar to expel liquid nitrogen.
