AELAB Electric-Heating Freeze Dryer LGJ-10FD / LGJ-30FD / LGJ-50FD for In-Situ Freeze Drying

The AELAB LGJ-10FD/30FD/50FD series of freeze dryers incorporates an electric-heating system that enables complete in-situ freeze-drying. This configuration simplifies operation, prevents sample contamination, and supports automated drying cycles under programmable conditions. The system records freeze-drying curves and allows data export via U-disk for traceable laboratory reporting.

These AELAB models integrate shelf heating and advanced PLC-based control, ensuring precise thermal regulation during pre-freezing, primary drying, and secondary drying phases. Users can clearly monitor the process through the embedded color touch screen and transparent chamber door.

⚙️ Design & Construction

The AELAB Electric-Heating Freeze Dryer LGJ-FD series features a Stainless Steel drying chamber, integrated condenser, and vacuum system designed for stable thermal control. The 7-inch color touchscreen provides real-time visualization of temperature segments and drying curves. A colorless transparent organic-glass chamber door enables clear viewing of the freeze-drying process. The shelf system includes uniform heating for controlled sublimation dynamics, supported by a high-capacity condenser rated to < -56°C (optional -80°C).

🔬 Working Principle / Testing Method

The freeze-drying process stabilizes samples by freezing them and reducing chamber pressure to sub-10Pa vacuum levels. Heat is applied through the electric-heated shelves, driving sublimation from solid ice to vapor. The condenser traps the vapor, maintaining continuous drying efficiency. Temperature programs include up to 40 stored schemes with 40 segments each, permitting precise control over every drying phase.
