Large Scale Vacuum Freeze Dryer is used in Bio-Pharma industry to freeze dry and store drug and medicinal product, materials, other biomaterials. Also used in food industry to freeze dry fruits and vegetables, fish and meat, Processed and raw food material to increase their shelf life and maintain quality.

Laboratory Bench-top Freeze Dryer

The Bench-top Series boasts a 3-4 kg per 24 hour condensing rate. For water based samples, -55°C condenser is the perfect choice. For samples containing solvents or with low eutectic points, -80°C condenser provides maximum performance. Designed for maximum flexibility and performance, Benchtop Freeze dryers can be customized with a range of accessories to support the needs of Laboratories and Research/Product Development teams.
