Pilot Freeze Dryer 0.7m² BK-FD50S (CAT#: STEM-LT-0605-ZJF)

This series of freeze dryers offers advanced control features, precise temperature regulation, and a durable chamber design for reliable performance in demanding applications. The shelf temperature is highly uniform, the cold trap reaches below −80°C, and models with stoppering support vial sealing. Designed for scaling from research to production, it accommodates large sample volumes with consistent drying quality.
