Pilot Standard Freeze Dryer LPFD-F21

Our Labtron Pilot Standard Freeze Dryer is designed for small-scale testing and preservation of various sample types, including pharmaceuticals, food products, and biological materials. It features a 0.3 m² drying area and can hold up to 8 kg of ice, making it highly suitable for research and development purposes. With a bulk drug capacity of 3 kg per batch and the ability to accommodate 1240 vials of 16 mm diameter or 650 vials of 22 mm, it can handle a wide range of sample volumes. This makes it an excellent choice for pilot-scale testing before full-scale production, especially in laboratory or R&D environments.

Our Labtron freeze dryer is equipped with a 7-inch intuitive touch screen that provides users with real-time monitoring of key parameters such as vacuum pressure, cold trap temperature, material temperature, and shelf temperature. The system records data every minute, helping to construct detailed freeze-drying curves and ensuring accurate tracking of the drying process. Users can easily access operational information briefly, and data can be analysed offline, exported, printed, or stored in PDF format for reporting or regulatory compliance. This interface not only simplifies the user experience but also improves process transparency and control.

This freeze dryer is powered by Labtron’s independently developed PLC (Programmable Logic Controller) system, which supports both automatic and semi-automatic modes of operation. This provides flexibility in adjusting the drying process according to specific sample requirements. The system also enables real-time data modification, allowing operators to change parameters during operation without interrupting the freeze-drying cycle. For safety, the freeze dryer is equipped with a compressor restart delay mechanism and an integrated thermal overload protection module. These features work together to prevent system damage caused by overheating or power surges, helping ensure reliable, long-term performance.

Our freeze dryer features a high-performance refrigeration system supported by hermetic compressors, one of which is dedicated to cooling the other. This design enhances overall efficiency and enables rapid cooling of the cold trap and shelves. The cold trap can reach a no-load temperature as low as -70°C, which accelerates moisture removal during sublimation and increases the ice-holding capacity. In addition, the silicone-oil-based thermal system ensures uniform and accurate temperature control across all shelves. The system also achieves a vacuum level as low as 1 Pa, which minimizes oxidation and thermal damage to sensitive materials, ensuring sample integrity is preserved throughout the process.

Our Labtron Pilot Standard Freeze Dryer combines compact design, robust performance, and user-friendly operation, making it an ideal solution for laboratories and pilot-scale production facilities. It features a vertical structure with a cylindrical material chamber, saving floor space while maintaining accessibility. The unit supports up to 36 programmable temperature stages per recipe, and users can store up to 50 customized recipes for repeat use. With its real-time data logging, vacuum monitoring, and protective design features, the freeze dryer ensures high-quality results and long-term operational safety. It is particularly well-suited for applications in pharmaceutical research, food preservation, and biotech sample development.
