Critical Point Dryers

Critical point drying is an established method of dehydrating biological tissue prior to examination in the scanning electron microscope. The technique was first introduced commercially for scanning electron microscopy (SEM) specimen preparation by Polaron in 1970. The original design concepts, which included a horizontal chamber, are still embodied in the design of the E3000 and E3100 systems.

A more recent addition to our product range is the K850 Critical Point Dryer with vertical chamber, which includes built-in heating and cooling. The larger K850WM model is designed to dry a 6? wafer.
