Jul 06, 2020 · The Oven dry method is widely used for the determination of water content. The loss of weight that happens due to drying results in the measurement of the moisture content of the sample. The temperature at which the sample is oven-dried ranges from 110 o C +- 5 o C. The oven-dried mass is usually recorded after 12 to 24 hours.
Dry or dehydrating – used in removal of moisture from samples. Sterilizing – used in destroying removal of bacteria or micro-organisms from laboratory equipment. Annealing –used in the removal of hardness of a material by relieving the internal stress of a material. Evaporating-used to turn moist into vapor.

Rationale: Carbon stable isotope analysis of bulk samples and fatty acids is an established method for tracing carbon flow pathways and reconstructing trophic interactions, but there is no consensus on which sample drying method should be used for sample preparation. The aim of this study was to determine if freeze-drying and oven-drying treatments used to prepare …
Air Drying Ovens are useful for drying soil, aggregate, and fire-proofing samples as well as other procedures calling for air drying at room temperature. While the 105°F (41°C) maximum temperature is below 140°F (60°C) allowed for some procedures, drying is still rapid and efficient because of the high air flow of 1—4 air changes per minute.
Nov 16, 2020 · The apparent porosity results were influenced by the drying methods, especially when the samples were submitted to a temperature of 105 °C. Oven drying results in apparent porosity significantly higher than those determined by solvent exchange or lyophilization. This method causes desaturation, desorption, and partial dehydration in the paste.
