An optimum volume of an extraction solvent is the calculated volume of an extraction solvent needed to extract all the desired solute from a given mass of a solid material based on the liquid to solid ratio experimentally established.
A Fractional Volume of an extraction solvent is a fraction of the optimum volume of the extraction solvent, into which the optimum volume of an extraction solvent is equally divided.
or
A Fractional Volume of an extraction solvent is an equal fraction of the optimum volume of the extraction solvent, into which the optimum volume of an extraction solvent is divided.

If 100ml hot water is required to extract all the tea from a tea bag, then 100ml hot water is the optimum volume of the extraction solvent. Ten 10ml volumes of hot water are fractional volumes of an extraction solvent i.e. hot water. Each fractional volume of an extraction solvent can then be used to extract the tea from the tea bag in a single extraction cycle. To use all the ten fractional volumes of the extraction solvent it would need to carry out the extraction in ten extraction cycles. Should one opt to use 20ml of hot water to extract the tea from the tea bag, then the optimum volume of the extraction solvent, 100ml ought to be divided into five fractional volumes of an extraction solvent (hot water), each of which equals 20ml. The fractional volume of the extraction solvent of 20ml would then be used in each extraction cycle.

Fractional Volume of an extraction solvent is a fraction of the optimum volume of the extraction solvent obtained by dividing the optimum volume of the extraction solvent needed to extract all of the desired solute from a given mass of the solid material into equal smaller volumes for use in separate extraction cycles
If 100ml of an extraction solvent is the optimum volume that would extract all the herbal solute from a medicinal herb, then 100ml/2 gives a fractional volume of an extraction solvent of 50ml, 100ml/3 gives a fraxtional volume of an extraction solvent of 33.333ml
100ml/4 gives a fraxtional volume of an extraction solvent of 25ml,
1/5 x 100 ml gives a fraxtional volume of an extraction solvent of 20ml.
Using fractional volumes of an extraction solvent for extraction purposes gives better extraction yields than using the optimum volume of an extraction solvent as a whole.

Regarding the product Essential CBD Extract, it is an oil composed mainly of natural active ingredients. It is therefore healthy for your body, and should not cause side effects, which is unfortunately not the case with all products of this kind. Let's find out without delay what are the main ingredients that make up the Essential CBD Extract product, and what their effects are: As you will have noticed following the natural and beneficial ingredients contained in the composition. By giving the right dose of plant-based cannabinoids, we can restore balance in the body. What diseases does hemp work? Cannabis therapy aimed at aligning the endocannabinoid system will have an effective effect on diseases caused by disturbances in the endocannabinoid system. The easiest way is to say this: Essential CBD Extract South Africa contains substances called cannabinoids.The diseases are associated with an imbalance in the body and with "disturbances" in the communication of the endocannabinoid system.
