A freeze dryer which is also called a lyophilizer, is a type of lab equipment that dehydrates materials with a low temperature process. First, the item is frozen, then in the second phase sublimation occurs which is when the substance transitions from a solid to a gas state and skips the liquid state. The last phase is the secondary drying phase which is also called adsorption.
