URS

There is a URS to Process envelope correspondence that is important to your production, regulatory, and validation programs. When you are starting a new program involving lyophilization, consider starting the process of obtaining a freeze dryer knowing what the product characteristics are, and then allow product, facility and process requirements to dictate the specifications.  Having this step by step program will allow you to build a URS that reflects the hardware, software, and performance envelope that will provide the least risk to your company.  Write the specs so that the resultant machine helps to ensure that the product can be successfully processed in this dryer, as specified in the URS.  If you are not able to do this with in-house expertise, allow Applewood Scientific to assist you in this important starting point.
