Freeze drying is the go-to method for stabilizing sensitive biologicals, especially in pharma and biotech. But it’s often misunderstood or oversimplified. This infographic breaks down the process, its stages, and its impact on product integrity—fast. 

What’s Inside the Infographic 

The asset walks through the three core phases of lyophilization: 

  • Freezing: Product is cooled below its eutectic point to solidify water content. 

  • Primary Drying (Sublimation): Pressure is reduced and heat is applied to convert ice directly into vapor. 

  • Secondary Drying (Desorption): Remaining bound water is removed to achieve final moisture specs. 

Each phase is illustrated with temperature-pressure dynamics, equipment visuals, and product stability checkpoints. The layout is optimized for quick reference during formulation planning or tech transfer discussions.
