Critical process parameters for Lyophilized Product Development:
– Freezing temperature
– Primary drying temperature
– Secondary drying temperature
– Time for annealing
– Pressure and time
@FRD
Liquid nitrogen is one of the safest cooling agents for pharmaceutical use. It can ensure extremely low temperature, which is required for freeze drying in lyophilization process.
Liquid nitrogen also offer a wider processing window to added flexibility and productivity benefits.
