Pilot Standard Freeze Dryer LPFD-F20

Our Labtron Pilot Standard Freeze Dryer provides a drying area of 0.2 square meters and can hold up to 8 kilograms of ice during operation. This capacity is ideal for small-scale freeze-drying projects, including laboratory tests and preservation tasks. It allows researchers and manufacturers to process medicines, food products, and biological samples in controlled batches before scaling up to full production. The moderate size ensures efficient space use while offering enough capacity to handle a variety of samples, making it a flexible tool for research and pilot testing environments.

The refrigeration system in this Labtron freeze dryer features two hermetic compressors that work together in a unique way. one compressor actively cools the other. This design boosts overall efficiency and accelerates the refrigeration process, helping the system reach the desired temperatures quickly. Additionally, it uses environmentally friendly refrigerants with international safety standards. The system is engineered to operate with minimal noise and vibration, providing a stable and quiet working environment, which is especially important in laboratory and production settings where noise reduction and equipment stability can impact both user comfort and process reliability.

Our Labtron freeze dryer offers precise temperature control, with shelves capable of operating between -45°C and +50°C. Under no-load conditions, the shelf temperature can go as low as -55°C, providing the flexibility needed for various freeze-drying protocols. The system is equipped with an advanced PLC (Programmable Logic Controller) that supports both fully automatic and semi-automatic operation modes. This automation allows users to customize and monitor the freeze-drying process closely, ensuring that temperature stages and timing are accurately followed. Such control helps improve product quality, repeatability, and overall process efficiency by minimizing manual intervention and errors.

To safeguard samples during operation, the Labtron freeze dryer continuously monitors the vacuum pressure in real time. If the vacuum pressure fails to reach the preset level within the designated timeframe, the system automatically shuts down the vacuum pump to prevent damage. At the same time, a solenoid valve opens to allow air into the vacuum chamber, maintaining the shelf temperature at a safe, normal level under atmospheric pressure conditions. This feature prevents sudden temperature fluctuations or sample damage that could occur if vacuum conditions were lost abruptly. The vacuum chamber effectively functions like an ultra-low temperature freezer, providing extra protection for sensitive samples throughout the freeze-drying process.

Our Labtron freeze dryer offers several advanced features that make it a valuable tool for research and pilot-scale production. These include a data-saving frequency function and advanced data management system that meticulously records user logins, operational activities, freeze-drying curves, and alarm records. It has a silicone-oil-based refrigeration system, customizable recipe controls with up to 50 recipes, and real-time vacuum monitoring for safety and efficiency. The unit includes USB ports for easy data export, and its compact size fits well in laboratory environments. It is widely used in pharmaceuticals, food processing, and biological sample preservation, helping companies and researchers test and perfect products on a smaller scale before moving to full production.
