Spin Freezer was devised to aim for both freezing and primary drying of products in ampoules. The centrifugal action with freezing will expedite the drying process in ampoules by freezing samples to a thin layer on one side of the ampoules. The freezing of ampoules is then followed by primary drying and secondary drying. Sublimation of ice takes place under a vacuum during the primary drying stage and is followed by the secondary drying stage in the secondary drying manifolds.
The spin freeze set includes a control box with a base plate, an acrylic chamber with a gasket, and 5 sets of interchangeable aluminium carriers, each designed to handle different-sized ampoules.
