In-Situ Freeze Dryer - Compact Lyophilizer for Fruits and Vegetables - -40°C - 1 to 8 kg/Batch

The Master Science In-Situ Freeze Dryer freezes and dries samples on the same shelves, so material never has to be moved between a freezer and a drying chamber. This in-situ design avoids contamination during transfer and is well suited to small-batch freeze drying of fruits, vegetables and similar foods.

Three sizes provide shelf areas of 0.12, 0.34 and 0.55 m², handling 1 to 8 kg per batch. The condenser reaches -40°C, shelf temperature is adjustable to help develop drying processes, and a colour touch panel on the Master Science In-Situ Freeze Dryer shows sample and condenser temperatures and vacuum as values and curves.

Problems the Master Science In-Situ Freeze Dryer Solves

Moving frozen samples between units risks contamination and thawing. The Master Science In-Situ Freeze Dryer helps with:

• Contamination during transfer: Samples stay on the same shelves throughout.
• Unclear drying progress: Curves and a window show what is happening.
• Time-consuming defrost: A single button starts defrosting.
• Process development: Adjustable shelf temperature allows optimisation.
