The concentration of glycerol used for lyophilization?
Typically, glycerol is used at a concentration of 5-10% in the culture medium to protect cells during freezing and lyophilization. The optimal concentration may vary depending on the cell type and specific lyophilization protocol being used. It is important to optimize the concentration of glycerol to ensure maximum cell viability during the lyophilization process.
Is lyophilization a sterilization process?
yesOnly If the process is followed by standards and protocol.The lyophilization process generally includes the following steps:Dissolving the drug and excipients in a suitable solvent, generally water for injection (WFI).Sterilizing the bulk solution by passing it through a 0.22 micron bacteria-retentive filter.Filling into individual sterile containers and partially stoppering the containers under aseptic conditions.Transporting the partially stoppered containers to the lyophilizer and loading into the chamber under aseptic conditions.Freezing the solution by placing the partially stoppered containers on cooled shelves in a freeze-drying chamber or pre-freezing in another chamber.Applying a vacuum to the chamber and heating the shelves in order to evaporate the water from the frozen state.Complete stoppering of the vials usually by hydraulic or screw rod stoppering mechanisms installed in the lyophilizers.Source..

What is lyphilization?
Lyophilization is a process where water is removed from a product by freezing it and then subjecting it to very low pressure, causing the ice to sublimate directly from solid to vapor without passing through the liquid state. This process helps to preserve the product by reducing the moisture content and extending its shelf life.
Incas well known invention?
Quote from the Related Link: "The basic process of freeze-drying food was known to the ancient Peruvian Incas of the Andes. Freeze-drying, or lyophilization, is the sublimation/removal of water content from frozen food." See the Related Link.
What are the the uses of stopper?
Stoppers are commonly used to seal containers such as bottles or test tubes to prevent spillage or contamination. They are also used in laboratories to control the flow of liquids or gases in experiments. In addition, stoppers can be used as plugs in sinks or drains to block water from flowing.
