A small-scale pilot freeze dryer. It adopts the same design principles as pilot freeze dryers, featuring the same dual-chamber design, shelf temperature control system, and a wider variety of freeze-drying R&D tool accessories than industrial freeze dryers. It provides high-performance tools for the early development and later optimization of freeze-drying formulations. Before scaling up the freeze-drying process, this tool helps you deeply understand the changes in key parameters during the freeze-drying process, making it very valuable during the scale-up. All freeze-drying processes of industrial freeze dryers can be realized on this MINI freeze dryer, allowing process exploration and optimization for small quantities of precious samples on a very small freeze dryer.
