Freezemobile Shell Bath Freezer

The Freezemobile Shell Bath, a floor model shell bath available in a -75C configuration, helps to decrease manifold freeze drying time. The FSB rotates the flask on its axis thereby coating the interior surface of the flask with frozen product. This increases the surface area of the product-to-energy input, as well as vapor removal; thus helping to reduce the freeze drying process to the shortest time possible when utilizing flasks and a manifold system. 

The FSB is available with the choice of one or two baths contained within the same cabinetry.
