Pilot Standard Freeze Dryer LPFD-F22

Our Labtron Pilot Standard Freeze Dryer offers a drying area of 0.4 m² and an ice holding capacity of 8 kg, making it suitable for small-scale freeze-drying tasks. It can handle a variety of samples, including medicines, food, and biological materials. With a bulk drug loading capacity of 4 kg per batch and the ability to hold 1240 vials of 16 mm diameter or 650 vials of 22 mm, it supports a wide range of sample sizes. This makes it ideal for laboratory testing and sample preservation before moving on to large-scale production.

Our Labtron freeze dryer uses shelves with a circulating heat transfer fluid, which allows for both refrigeration and heating directly within the shelves. This design ensures uniform temperature distribution across all shelves and enables precise control of shelf temperature, ranging from -45°C to +50°C. The shelves maintain a uniformity of ±1°C, ensuring consistent freeze-drying results. Additionally, the vacuum chamber works like an Ultra-Low Temperature (ULT) freezer, providing excellent sample protection during the process.

Our Labtron freeze dryer incorporates a real-time vacuum pressure monitoring system that safeguards the vacuum chamber. If the vacuum pressure does not reach the setpoint within a specific time, the system automatically shuts down the vacuum pump to prevent damage. Then, a solenoid valve opens to allow air in, stabilizing the shelf temperature at atmospheric pressure. The system’s PLC control offers automatic or semi-automatic operation, and the compressor includes a restart delay and thermal overload protection to prevent overheating and ensure reliable operation.

Our freeze dryer comes with a PLC system that provides seamless control, allowing automatic or semi-automatic operation. It also offers continuous data monitoring of the freeze-drying process and material status. The system records important data offline, making it easy to analyze, print, or store information. Moreover, the device tracks the cumulative operating hours of the vacuum pump, helping users determine the best time to perform maintenance such as oil changes, which helps extend the equipment’s lifespan.

Our Labtron freeze dryer is designed with a vertical cylindrical material chamber and a compact footprint of 740 × 850 × 1280 mm, making it space-efficient for lab use. It features four shelves with 45 mm spacing, allowing high sample capacity with precise control. Its two-stage rotary vane vacuum pump ensures stable vacuum conditions, while air cooling keeps the system running efficiently under normal lab ambient temperatures (?26°C). These features combined make it a reliable and user-friendly tool for small-scale freeze-drying in research and development, as well as pilot-scale production.
