A countercurrent version of this technique is performed in a Craig apparatus or a mixer-settler.
A countercurrent version of this technique is performed in a Craig apparatus or a mixer-settler. Thistechnique can be used alongside a quaternary ammonium salt in a form of catalysis. A version of thistechnique using isoamyl alcohol and phenol-chloroform is used on proteins and DNA. It's not titration, buta funnel with a stopcock on the bottom is commonly used to perform this technique. This technique, which iscommonly done as part of the (*) workup of a microscale reaction, relies on a substance having a decent partitioncoefficient between an aqueous phase and an organic phase, which layer on top of one another. For 10 points, namethis technique in which a mixture is separated based on its differential solubility between two non-mixing liquids.
