Here is an overview of our laboratory freeze-dryer, which handles product capacities from 2.5 kg to 24 kg per drying cycle.
The version with LSCbasic control is particularly suited to standard applications in round-bottomed or similar flasks and small quantities in product trays and other containers. For advanced applications requiring more process control and/or temperature-controlled shelves for the product, we recommend the LSCplus range.
Almost all models are available with ice condenser temperatures of approx. -55 °C (main application: aqueous solutions) and -85 °C and -105 °C (for products with low freezing points, e.g. solvents).
Standard (LSCbasic/LDplus) / Laboratory Freeze-Dryer
Drying manifold for eight round-bottom flasks, wide-neck filter bottles or ampoule distributors
Base Model
Compact, high-performance tabletop unit for effective lyophilisation of specimens in your everyday lab activities. The LDplus user interface makes the work very easy. You can choose from a wide range of configurations to adapt the freeze dryer optimally to your specific needs. The condenser temperature of -55 °C enables the drying of aqueous products.
