Aug 07, 2017 Optical coherence tomography freeze-drying microscopy (OCT-FDM) is a novel technique that allows the three-dimensional imaging of a drug product during the entire lyophilization process. OCT-FDM consists of a single-vial freeze dryer (SVFD) affixed with an optical coherence tomography (OCT) imaging system. Unlike the conventional techniques, …

Freeze-substitution is a chemical process of dehydration, performed at temperatures low enough to avoid the formation of ice crystals. During freeze substitution ice in the samples is replaced by an organic solvent and subsequently by resin and may be polymerized at low temperatures or by standard methods. Leica Auto Freeze Substitution Procedure.
