Pilot-Scale Freeze Dryer BK-FD20/30 Series with Vacuum and Temperature Control

The BK-FD20/30 Series comprises pilot-scale freeze dryers designed for advanced lyophilization processes integral in biotechnology, molecular diagnostics, and bioprocessing workflows. Available in standard (BK-FD20S, BK-FD30S) and stoppering models (BK-FD20T, BK-FD30T), these vacuum freeze dryers incorporate precise temperature and vacuum controls to support sensitive sample preservation and water removal.

Key technical specifications include:

• Cold trap temperature minimum: -80ºC for effective sublimation and ice capture.
• Tray temperature range: adjustable from -50ºC to +70ºC, enabling versatile freeze drying cycles and secondary drying phases.
• Vacuum level: below 0.1 mBar, ensuring efficient moisture extraction essential for lyophilization quality.
• Cold trap volume: 13.5 L, accommodating substantial ice accumulation during freeze drying.
• Water capture capacity: up to 6.5 kg/24h, supporting high-throughput freeze drying demands.
• Liquid sample capacity: 4.5 L (BK-FD20 series) or 7 L (BK-FD30 series), suitable for pilot-scale biopharmaceutical and synthetic biology sample processing.
• Physical dimensions:
• Cold trap size: 240 x 300 mm (diameter x height)
• Freeze-drying chamber: 470 x 485 x 420 mm
• Trays: 305 x 405 x 17 mm, heated by silicone oil ensuring uniform temperature distribution for product stability.
• User interface: Touch-screen LCD allowing easy programming and control.
• Data management: Historical data storage up to one month and USB port for data export, critical for reproducibility and regulatory compliance in molecular cloning and biomanufacturing environments.
• Included vacuum pump: rated at 22 m³/h, providing reliable vacuum generation tailored for freeze-drying cycles.

This series supports pre-freezing and drying in a single integrated chamber, optimizing laboratory space and processing workflow. Models with stoppering function allow for vial sealing under vacuum, crucial for aseptic processing in clinical diagnostics and biopharmaceutical production.

Widely used in biotechnology research and development, these pilot-scale freeze dryers facilitate essential lyophilization steps in gene editing, synthetic biology, and bioprocessing pipelines, offering precise environmental control to preserve biological samples and active pharmaceutical ingredients.

The BK-FD20/30 Series is a robust solution for pilot-scale lyophilization, ideal for laboratories focused on molecular biology, cell imaging sample preparation, and downstream bioprocess applications requiring reliable freeze drying performance.
