What is Lyophilisation?

Advantages of the Lyophilisation technique:

  1. The temperature at which the product is subjected is below the one that at which many unstable substances undergo chemical changes.
  2. Due to the low temperature that is operated, the loss of volatile constituents is minimal, the danger of microbial contamination is reduced and the enzymatic preparations do not suffer alterations.
  3. Oxidation phenomena are eliminated, because it operates and it is packed under high vacuum.
  4. The high porosity of the product facilitates a rapid reconstitution by the addition of water or the suitable solvent.
  5. As the remaining moisture is negligible, the product can be stored for an unlimited time, constituting products with long stability.

All these particularities can be summarized in: Optimum stability, Easy, fast and complete solubility, Unlimited conservation, Good protection against harmful external influences, Rapid availability of use.
