Product Overview
Labotemp Vacuum Freeze Dryer LFD-204 offers dependable freeze-drying with an integrated manual capping system, suitable 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 to protect samples from moisture and contamination.

Key Benefits

• Secure sample sealing via manual capping system enabling vacuum sealing of vials after freeze drying.
• Smart process management with 7-inch touchscreen HMI, real-time monitoring, automatic parameter storage and USB data export.
• Reliable laboratory design with energy-efficient Secop refrigeration, corrosion-resistant components and safety features for long-term operation.
