Pilot Freeze Dryer 0.3m² BK-FD20S (CAT#: STEM-LT-0589-ZJF)

This large pilot freeze dryer features advanced control systems, precise temperature regulation, and durable stainless steel construction. With shelf temperature uniformity, ultra-low cold trap temperature down to −80°C, and reliable scalability, it supports efficient transition from lab development to pilot or production-level processing. Stoppering models provide automated vial sealing for pharmaceutical and biotech applications.
