title: [Chemico-analytical studies on the water content of the human tissues. 1. Investigation of the method of oven-drying at 105 degrees C (author's transl)].
abstract: By heating at 105 degrees C in a constant temperature electric oven, a 35 ml crucible becomes completely dry in an hour and 2 grams of human tissue in 48 hours. Within 5 minutes after taken out from an oven and allowed to stand in a room, a dried crucible and tissue become wet with moisture in the air and their water content reaches equilibrium and saturation. Thereafter the weight of the crucible remains constant for 5 days, that of the tissue for 30 minutes. A major portion of increased weight of a crucible containing tissue by moisture depends on the moisture of a crucible, whereas the moisture of tissue is extremely small being under 1.0%. Consequently it is sufficient to cool samples taken out from an oven in a room and to weigh within 30 minutes. There is no necessity for cooling them in a desiccator.
