Freeze drying vs oven drying sediments at 40°C - OSF

Feb 21, 2021 · Wiki. A common method in the literature for drying lake and ocean sediment as well as soil samples is to dry them in an oven at 50°C and some as high as 60°C. Ovens are relatively inexpensive and common in most laboratories and hence readily available. The preferred method of drying samples of this type is to use a freeze drier.
