Fractional Volume of an extraction solvent

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.

extra virgin oil

Slang. Noun. It’s what pedophiles use on their pasta. The extra virgin part is when the girls he likes are very young inexperienced virgins.

Creep: hand me that extra virgin oil please. Girl: why do you call it that? It’s what pedophiles use on their pasta. The extra virgin part is when the girls he likes are very young inexperienced virgins. Girl: you’re a pathetic creepy guy who’s going to live with his mom for the rest of his life! Get tf away from me!
