低真空型電子顕微鏡
ニコン ESEM-2700L; Nikon Corporation, Tokyo, Japan. This environmental scanning electron microscope allows direct observation of wet, dry and conductive and/or non-conductive specimen. Water vapor is provided to the specimen chamber and the limited environmental gas pressure is water vapor saturation value of 2700 Pa at ambient temperature. In the low vacuum mode, the specimen chamber pressure can be regulated from 100 to 2700 Pa. The microscope is equipped with a cooling stage ( -20° from ambient temperature, heating stage (ambient to 1000°C), tensile stage; and micro-manipulator/injector, which allows dynamic observation of the behavior of manipulated specimens.
