From: A comparative study of freeze-drying heat transfer in polymeric vials and glass vials

Overview of the experimental freeze-drying setup and experimental comparison of the vial total heat transfer coefficient. (A) Picture of 322 vials arranged on an individual freeze-drying tray and inside the shelf. (B) Comparison between the experimental value of heat transfer coefficient (Kv) between hybrid COP and glass vials. Data summarizes n = 3 runs in which 322 vials were studied experimentally at various freeze-drying conditions.
