Critical Point Dryers
Quorum make a range of critical point dryers to meet the needs of electron microscopy (EM) and other applications.
Critical point drying (sometimes called supercritical drying) is an established method of dehydrating biological tissue prior to examination in a scanning electron microscope (SEM). The technique was first introduced for SEM specimen preparation by Polaron (the forerunner of Quorum) in 1971, and the original design concepts, which included a horizontal chamber, are still embodied in the Quorum E3100 critical point dryer.
A more recent addition to our product range is the K850 critical point dryer with vertical chamber and built-in heating and cooling. The larger K850WM model is designed for semiconductor applications and will dry a 6″ wafer.
