Lyophilization Validation: A Regulatory Perspective

• Studies where shelf temperature and chamber pressure were offset from commercial set-points – High and low shelf temperature – High and low chamber pressure • Sometimes time is also varied during these studies • Not required for fixed cycles but provides confidence in lyophilization process 18

The Significance of Humidity Control in GMP Compliant

Aug 15 2018Figure 1: Effect of RH% on materials in static locations It is important to note the relationship between relative humidity (RH%) and air temperature as variations in temperature also will affect the RH% For example a sufficiently large drop in air temperature can result in water vapor condensing out Alternatively cold surfaces will cause condensation


N Vishal Gupta et al/International Journal of PharmTech Research 2016 9(4) pp 220-226 221 The standard temperature and pressure of an autoclave Processes conducted at high temperatures for short time periods are preferred over lower temperatures for longer times

Vacuum Pump Capacity Ratings

The capacity for vacuum pumps is specified in a couple of different ways depending on the type of vacuum pump and the manufacturer It is important to know the ACFM rating of the pump which expresses the actual cubic feet per minute inlet capacity at a specific vacuum level
