Labotemp Vacuum Freeze Drying Machine LFD-203 delivers dependable lyophilization for pharmaceutical, biotechnology, food, environmental, and research laboratories requiring larger sample capacity and consistent drying performance. This floor-standing system features a 0.12 m² freeze-drying area, four stainless steel shelves, -60°C cold trap (optional -80°C), and 2 Pa ultimate vacuum to efficiently remove moisture while preserving the structure and activity of heat-sensitive materials. Its transparent corrosion-resistant drying chamber provides clear sample visibility, making it ideal for biological specimens, vaccines, plant extracts, microorganisms, laboratory chemicals, and other valuable research samples.
Built for reliable laboratory operation, the LFD-203 integrates a 7-inch touchscreen HMI with real-time monitoring of vacuum, temperature, and freeze-drying curves, alongside USB data export for complete process documentation. The energy-efficient Secop refrigeration system ensures stable low-temperature performance, while delayed vacuum pump start, automatic parameter storage, vacuum alarms, inert gas filling port, and one-touch defrost enhance operational safety and convenience. Designed with corrosion-resistant components and an industrial-grade control system, the LFD-203 provides long-term durability and consistent freeze-drying performance for routine laboratory and pilot-scale applications.
