| The top aqueous phase was pipetted into a fresh tube, and RNA was precipitated with 0.5 ml isopropanol. |
| Although AVB has been shown to be relatively photostable in the polar protic solvent isopropanol it was relatively photolabile in the nonpolar solvent cyclohexane. |
| They also heard that isopropanol, a chemical used in cleaning products, was found to be in the liquid when it was analysed. |
| For example, each molecule of isopropanol has eight hydrogen atoms in one of three environments. |
| In 2013, the most commonly used solvents were alcohols, mainly ethanol, n-butanol, isopropanol and methanol. |
| The chemicals included aliphatic hydrocarbons, glycol ethers, isopropanol, limonene, naphtha, oils, and varnishes. |
