1 / 10The Swiben SJ-1S is a benchtop vacuum freeze dryer (lyophilizer) configured without a top-press option. It pairs a low-temperature condenser with vacuum operation to remove moisture from frozen samples through sublimation.
The unit provides a single 300×400mm tray with a shelf area of 0.12m³ and a water capture capacity of 1-2kg per cycle. Its bulkhead temperature range of -50°C to 50°C and ±1°C uniformity support repeatable drying runs.
It is suited to laboratory, biological, and food-related applications where small-batch freeze drying is required.
Frozen material is held under vacuum (≤5Pa) while the condenser, operating at ≤-65°C, captures water vapor as samples sublimate. Controlled bulkhead temperatures between -50°C and 50°C with ±1°C uniformity drive the drying cycle.
Model: SJ-1S (Without Top-Press)
Benchtop laboratory freeze dryer with a condenser reaching -65°C, single 300×400mm tray, and 1-2kg water capture for lyophilization.
