Pilot Freeze Dryer 0.3m² BK-PFD20S (CAT#: STEM-LT-0585-ZJF)

The Pilot Freeze Dryer features a square cabinet made of SUS304 stainless steel and adopts silicone oil circulation heating to ensure uniform shelf temperature distribution. With a temperature variation within ±1°C and a cold trap capable of reaching −80°C, it is ideal for small-scale freeze-drying of sensitive or solvent-based samples in research and industrial trial settings.
