Pilot Top Press Freeze Dryer LPFD-A14

Labtron’s Pilot Top Press Freeze Dryer is specifically designed for use in the pharmaceutical and biotech industries. It is well-suited for freeze-drying injectable drugs, vaccines, and sensitive biological materials. The system ensures product safety and high-quality drying by offering precise temperature control through silicone-oil-based circulating shelves and close vacuum monitoring. Its ability to store multiple recipes and handle bulk drug or vial-based formats makes it ideal for small-scale production and process optimization before scaling up.

Temperature control is critical for the freeze-drying of sensitive materials, and Labtron addresses this with circulating heat transfer fluid inside the shelves. This design allows both heating and cooling to be applied uniformly across all layers, helping maintain consistent product temperature during each stage. The shelf temperature remains stable within ±1°C under steady-state conditions, which ensures better drying results and prevents damage to delicate samples.

Safety is built into multiple parts of the Labtron freeze dryer. It features real-time vacuum pressure monitoring to detect system issues early. If the vacuum level doesn’t reach its setpoint in time, the system automatically shuts down the vacuum pump and opens a solenoid valve to equalize pressure, protecting both the machine and the samples. Additionally, a molded T-structure sealing system prevents leaks, and the compressor includes a restart delay and thermal overload protection to avoid overheating.

Yes, the Labtron freeze dryer offers high customization flexibility. Users can store up to 50 recipes, each with 36 temperature stages, and assign unique names to them. Time and temperature can be modified in real time while the process is running. The intelligent control system waits for temperature setpoints before starting countdowns, and it automatically adjusts the drying time if parameters are changed mid-process. This allows researchers and manufacturers to fine-tune freeze-drying protocols for different products.

The freeze dryer is designed for efficient lab or pilot-scale use. It has a 0.4 m² drying area, 10 kg ice holding capacity, and can handle both vials (up to 1,650 with Ø16mm) and bulk drug loads of 4 kg per batch. It reaches vacuum levels as low as 1 Pa and cold trap temperatures down to -86°C. The compact unit is easy to install in a standard lab, and its air-cooling system ensures quiet and stable operation. Combined with user access control and a 7-inch touchscreen for easy monitoring, it offers a complete package for advanced freeze-drying needs.
