It was then warmed on a water-oven, kept in a vacuum desiccator over solid paraffin, and the weight estimated. ❋ C. F. Cross (N/A)
This is then dried in the water-oven, when if any boric acid compound is present, a bright reddish-pink stain is produced on the paper, which is turned blue on moistening with dilute alkali. ❋ H. A. Appleton (N/A)
The last traces of solvent remaining in the flask are removed by gently warming in the water-oven, and the flask cooled and weighed, thus giving the amount of unsaponifiable matter. ❋ H. A. Appleton (N/A)
The residue retained by the filter paper is washed with petroleum ether until free from fat, dried in the water-oven at 100° C. and weighed. ❋ H. A. Appleton (N/A)
After being dipped in the beaker of water and once or twice in that with the alcohol, it is dried in the water-oven for about three minutes, and then weighed. ❋ Cornelius Beringer (1886)
_In assaying ores_, we term "moisture" all water which is lost by exposure in a water-oven at 100° C., and the "dry ore" is the ore which has been dried at this temperature. ❋ Cornelius Beringer (1886)
These are placed in the water-oven (fig. 20), and, when apparently dry, they are taken from the funnel, placed between glasses, and then left in the oven till they cease to lose weight. ❋ Cornelius Beringer (1886)
~ -- Five grams of the powdered sample is dried between watch-glasses in the water-oven for two hours, or till its weight is constant; and the loss is reported as water lost at 100° C. ❋ Cornelius Beringer (1886)
~Total Solids at 100° C. ~ -- Where simply the amount is required, take 100 c.c. and evaporate on the water-bath in a weighed dish; then dry in the water-oven, and weigh. ❋ Cornelius Beringer (1886)
Wash the precipitate with hot water, dry in the water-oven or at a low temperature. ❋ Cornelius Beringer (1886)
The method of determining moisture is to weigh out into the glasses 5 grams of ore, and dry in the water-oven until there is no further loss of weight. ❋ Cornelius Beringer (1886)
To reconvert it into carbonate, moisten with a few drops of ammonic carbonate solution, and dry in a water-oven. ❋ Cornelius Beringer (1886)
~ -- Take 5 grams of the carefully-prepared sample and dry in the water-oven till the weight is constant. ❋ Cornelius Beringer (1886)
In determining the percentage of moisture in these samples, the substance is dried on a water-bath or in a water-oven. ❋ Cornelius Beringer (1886)
