Emulsification of organic matter in a separatory funnel using a separatory funnel

BILON-LZ6 type separatory funnel oscillator (vertical oscillator) can be used for a variety of separatory funnels, which can greatly improve work efficiency and reduce work intensity. The products are flexible in use and easy to operate, and can be used in a variety of applications.

Then in the use sometimes there will be emulsification of organic matter in the separatory funnel, how to eliminate it, take a look at the following methods!

When the extraction and washing operation is carried out using a separatory funnel, the organic matter is washed with an alkali solution in particular, and after vigorous shaking, it tends to be difficult to separate due to the occurrence of emulsification without delamination. If the degree of emulsification is not serious, the separatory funnel can be slowly rotated in the horizontal direction and then left to stand for a while to eliminate the foam at the interface and promote delamination. If it is still not layered, add a proper amount of water, then shake it horizontally or place it overnight to separate the clear interface.

If the density of the solvent is close to that of water, it is easy to emulsify with water during extraction or washing. At this point, an appropriate amount of diethyl ether can be added thereto to lower the density of the organic phase, thereby facilitating delamination.

For an emulsion formed by a slightly soluble ester of water and water, it can be stratified by adding a small amount of an inorganic salt such as sodium chloride or ammonium sulfate.

Splitting funnel oscillator (vertical oscillator) use:

1. Extraction operation before environmental analysis

2. Extraction of natural foods and oils

3. Pesticide residue extraction

4. Extraction of harmful substances in the soil

5. Extraction of water pollution detection
