Abstract
A system to monitor and control a lyophilization process using a wireless network is disclosed which includes one or more wireless pressure and gas temperature sensors adapted to provide pressure and gas temperature measurements of the ambient environment, a lyophilization chamber, wherein the one or more wireless pressure sensors are distributed in one or more lyophilization vial trays, a vacuum pump, adapted to change the pressure with the lyophilization chamber, a heat exchanger adapted to modify temperature within the lyophilization chamber, and a controller adapted to collect pressure and gas temperature data from the one or more wireless pressure and gas temperature sensors, calculate sublimation rate of a product to be lyophilized using the collected pressure and gas temperature data, and adjust one or both of pressure and temperature within the lyophilization chamber such that the calculated sublimation rate stays within a predetermined envelope.
