Labotemp Pilot Freeze Dryer LFD-401 supports pilot-scale lyophilization for laboratory research and process development involving temperature-sensitive materials. Featuring a 0.2 m² freeze-drying area, this configuration provides a solution capacity of 3 L and water capture capacity of 4 kg per batch. Its tray system accommodates 2+1 layers, with tray dimensions of 300 × 345 mm and 70 mm spacing. Tray temperature operates from -50°C to +60°C, while its cold trap reaches a minimum temperature of -70°C. Gland-type silicone oil heating supports controlled tray heating during freeze-drying operations. Vial capacity varies according to vial diameter, accommodating up to 1,300 vials at Ø12 mm, 810 at Ø16 mm, or 430 at Ø22 mm.
Vacuum system reaches an ultimate vacuum degree of 1 Pa and includes a vacuum pump rated at 4 L/s. Process functions include low-temperature chamber pre-cooling, secondary refreezing, pressure-rise testing, adjustable vacuum control, and real-time monitoring of sample temperatures and vacuum levels. Closed-loop PID control supports thermal regulation, while freeze-drying curve management allows multi-profile storage and manual curve intervention during cycles. Additional functions include stage-specific process navigation, in-process formula adjustments, timestamped data logging, report generation, interlock safeguards, emergency protocols, and power-loss recovery. Available electrical configurations include 220 V and 110 V, both operating at 50/60 Hz, allowing selection according to site power requirements.
