Freeze Dryers for Sample Preparation

Freeze-drying specimen preparation for transmission electron microscopy (TEM) and scanning electron microscopy (SEM) is a well-established practice. It reduces the distortion and shrinkage effects that occur when a wet specimen dries by normal evaporation, as the method involves careful sublimation of frozen specimens under vacuum.

The K750X Freeze Dryer uses peltier cooling and operates under rotary-pumped vacuum. For more demanding applications, the K775X Freeze Dryer is cooled by liquid nitrogen and uses turbomolecular pumping.
