Freeze Dryer

Overview

Thumbnail image of Freeze Dryer Freeze dryers (lyophilizers) are used for sediments to remove moisture from samples, such as silt, mud, and soil, through sublimation, converting ice directly to vapor without melting. This process is crucial for preserving the structural integrity and chemical composition of delicate samples, ensuring they remain friable (powdery) rather than compressed.


Instrument Make and Model

Labconco FreeZone 12 Liter Console Freeze Dryer (2)


Estimated Measurement Time

The majority of laboratory samples will lyophilize in 12 to 48 hours. Drying time is heavily dependent on sample type, grain size and water content.
