In-situ Freeze Dryer

LC-F

Vacuum freeze-drying utilizes sublimation: materials are rapidly frozen at low temperatures, after which water molecules sublimate directly from ice to vapor under vacuum. Maintained at low temperatures throughout the process, the material preserves uniformly distributed ice crystals, eliminating concentration risks caused by dehydration. This mechanism prevents side effects such as foaming and oxidation. The end product features a porous “dry sponge” architecture, maintaining original volume for complete rehydration while minimizing physical, chemical, and biological degradation.

    Features

    In-situ freeze dryers are designed for drying in the same chamber where the material is initially processed, minimizing material transfer and potential contamination. 

    7-inch Color LCD Screen with PID Control

    Displays temperature and vacuum level, supports curve browsing for clear and intuitive monitoring.

    Glass-clear Acrylic Door for Drying Chamber

    Enables full-process visual observation by users.

    Split Structure of Drying Chamber and Cold Trap

    Enhances water capture capacity and shortens drying time.

    Vaccum Pump with Anti-oil Backflow

    Connected to the main unit via international standard KF quick connectors for simplicity and reliability.

    European Original Imported Compressor

    Paired with mixed eco-friendly refrigerants for rapid cooling and ultra-low freezing temperatures.

    Cold Trap with Pre-Freezing Function

    Can replace low-temperature refrigerators.

    Built-in Heat Exchanger

    Effectively reduces cold trap temperature and strengthens water capture capacity.

    In-Situ Freeze-Drying Capability

    Allows pre-freezing and sublimation of materials directly on the shelves (integration of pre-freezing and drying).

    Silicone Oil Thermal-Conduction System

    Equipped with a silicone oil thermal-conduction plate on the top layer for uniform temperature distribution in the drying chamber.

    Dual Working Modes (Manual/Auto)

    Manual mode enables exploration of freeze-drying curves for new materials.

    Automatic Vacuum-Controlled Heating Output

    Prevents material collapse caused by excessive heating.

    Nitrogen Charging Valve

    Supports filling with nitrogen or inert gas for post-drying preservation.

    Program Storage Function

    Stores 20 programs (36 segments per program), allows on-the-fly parameter modification during operation, and records final drying curves.

    Hydraulic Stoppering Function for Effortless Post-Drying Vial Sealing (Models with "T")
