The use of organic solvents in laboratory freeze-dryer

Freeze-dryers were initially intended to be used with water as a solvent. With new applications arising, products that are not soluble in water are increasingly present in chemistry applications. Consequently, freeze-drying is being used more and more in combination with organic solvents instead of water.Organic solvents and inorganic acids and bases are often used in research …
