Freeze dryers, also known as lyophilizers, are essential tools for preserving biological samples, pharmaceuticals, food, and other temperature-sensitive materials. By removing moisture through a low-temperature sublimation process under vacuum, these systems ensure product stability, extend shelf life, and maintain structural integrity.
Our collection of freeze dryers includes benchtop, pilot-scale, and production-scale models, with advanced features such as touchscreen control, programmable recipes, real-time temperature and vacuum monitoring, data export, and intelligent safety systems. Ideal for applications in biotechnology, pharmaceuticals, food research, and academic laboratories.
Whether you're developing vaccines, stabilizing enzymes, or preserving delicate samples, our freeze dryers deliver precision, performance, and reliability.
