Labotemp Vacuum Freeze Dryer LFD-204 offers dependable freeze-drying with an integrated manual capping system, making it well suited for laboratories handling pharmaceutical formulations, biological samples, vaccines, enzymes, and other moisture-sensitive materials. This floor-standing unit features a 0.08 m² freeze-drying area, three stainless steel shelves, a -60°C cold trap (optional -80°C), and an ultimate vacuum of 2 Pa to achieve efficient sublimation while preserving sample quality. The transparent corrosion-resistant drying chamber enables continuous process observation, while the manual capping function allows vials to be sealed under vacuum after lyophilization, helping protect valuable samples from moisture and contamination.
Designed for stable long-term laboratory performance, the LFD-204 combines a 7-inch color touchscreen HMI with intelligent process management, including real-time monitoring of vacuum, temperature, and freeze-drying curves, automatic parameter storage, and USB data export. The energy-efficient Secop refrigeration system maintains consistent low-temperature operation, while delayed vacuum pump start, vacuum alarms, inert gas filling, one-touch defrost, and corrosion-resistant components enhance operational safety and equipment durability. Its user-friendly controls and robust construction make it a reliable solution for routine laboratory and pilot-scale freeze-drying applications.
