  2. Mixing (process engineering) - Wikipedia

    en.wikipedia.org/wiki/Mixing_(process_engineering)

    Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...

  3. Stopped-flow - Wikipedia

    en.wikipedia.org/wiki/Stopped-flow

    Stopped-flow spectrometry enables the solution-phase study of chemical kinetics for fast reactions, typically with half-lives in the millisecond range. Initially, it was primarily used for investigating enzyme-catalyzed reactions but quickly became a staple in biochemistry, biophysics, and chemistry laboratories for tracking rapid chemical ...

  4. Compatibility (chemical) - Wikipedia

    en.wikipedia.org/wiki/Compatibility_(chemical)

    In addition, chemical compatibility refers to the container material being acceptable to store the chemical or for a tool or object that comes in contact with a chemical to not degrade. For example, when stirring a chemical, the stirrer must be stable in the chemical that is being stirred. Many companies publish chemical resistance charts.

  5. Separatory funnel - Wikipedia

    en.wikipedia.org/wiki/Separatory_funnel

    A separatory funnel, also known as a separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture into two immiscible solvent phases of different densities. [1]

  6. Gas blending - Wikipedia

    en.wikipedia.org/wiki/Gas_blending

    Gas blending is the process of mixing gases for a specific purpose where the composition of the resulting mixture is defined, and therefore, controlled. A wide range of applications include scientific and industrial processes, food production and storage and breathing gases.

  8. Homogenization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Homogenization_(chemistry)

    Milk homogenization is accomplished by mixing large amounts of harvested milk, then forcing the milk at high pressure through small holes. [7] Milk homogenization is an essential tool of the milk food industry to produce consistent levels of flavor and fat concentration. Another application of homogenization is in soft drinks like cola products.

  9. Piranha solution - Wikipedia

    en.wikipedia.org/wiki/Piranha_solution

    A typical mixture is 3 parts of concentrated sulfuric acid and 1 part of 30 wt. % hydrogen peroxide solution; [1] other protocols may use a 4:1 or even 7:1 mixture. A closely related mixture, sometimes called "base piranha", is a 5:1:1 mixture of water, ammonia solution ( NH 4 OH , or NH 3 (aq) ), and 30% hydrogen peroxide.
