For applications ranging from semiconductor analysis to materials inspection to tissue preparation, samples need to be handled under certain conditions. For example, the application of variable pressure scanning electron microscopes (SEMs) has recently become an important technique in material and life sciences. The capability of maintaining a variable pressure up to 100 Pa allows wet, oily, dirty, outgassing, and non-conductive samples to be examined in their natural state without significant sample modification or preparation.
To maintain variable pressures, the LEO 1530VP field emission SEM from LEO Electron Microscopy Inc., Thornwood, N.Y., offers high performance and ...
