Use of Freeze Drier - UCL Department of Geography

Use of Freeze Drier. For some analyses, e.g. lipid analysis, it is essential that sediment is freeze dried rather than oven dried. Freeze-drying is preferable to oven drying because it removes the water content without greatly altering the physical structure of the sediment. As a result, sediments containing clay are much easier to handle after
