Christ Alpha 1-2 LDplus -55 °C Freeze Dryer – 2kg

Product Details

Lyophilization, also called freeze drying, is by far the gentlest product drying method. It is based on the physical phenomenon of sublimation, which means a direct transition from the solid state to the vapour state without passing through the liquid state. The frozen products are dried under vacuum without thawing.

Compact, high-performance table-top 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.

Drying manifold for eight round-bottom flasks, wide-neck filter bottles or ampoule distributors
