evaporate to dryness

Thus, one would expect that the solvent should always evaporate to dryness first.

Solutions of peroxides often become explosive when evaporated to dryness or near-dryness.

On that basis, there should be places where local lakes evaporated to dryness and produced evaporite minerals.

The solution is then evaporated to dryness and the film formed on the cell is analysed directly.

After centrifugation, chloroform phases were mixed and evaporated to dryness under nitrogen atmosphere.

Methylated bile acids were produced by reaction at room temperature for one hour and subsequently evaporated to dryness under nitrogen.

If an instrument is not available, a known sample volume can be evaporated to dryness and brought to constant weight to give total solids by evaporation.

Due to the shock and light sensitive nature of organic peroxides, dipropyl ether should never be boiled or evaporated to dryness.

The pH was adjusted to 7.0 with 1 N HCl and the mixture was evaporated to dryness.

The reaction mixture was evaporated to dryness at reduced pressure, and the residue was chromatographed on alumina by using cyclohexane as the eluent.

The combined hexane layers were evaporated to dryness under a stream of nitrogen and the extracted cholesterol was dissolved in hexane for gas chromatographic analysis.

If you wish to do a quicker or more thorough clean-out of old oil or new, then 100% Isopropanol is your safe universal solvent that can evaporate to dryness.

LiF is prepared from lithium hydroxide and hydrogen fluoride or by dissolving lithium carbonate in excess hydrogen fluoride, evaporating to dryness and heating to red heat.
