A measured portion
An aliquot is a defined, measured portion taken from a larger amount of a material or solution. Dividing a larger quantity into aliquots gives a set of consistent portions to work with.
Why researchers use aliquots
Working from smaller aliquots can reduce how often a main stock is opened or handled, which supports consistency and organisation. Aliquoting is a general laboratory practice rather than anything specific to one material.
Aliquots and calculations
Because an aliquot is a measured volume of a solution at a known concentration, it relates directly to concentration maths. A reconstitution and aliquot calculator helps a researcher work out the volume that corresponds to a target quantity.
Frequently asked questions
Is an aliquot a measured portion?
Yes — it is a defined, measured portion of a material or solution in a laboratory context. It is not a dose.
How do aliquots relate to concentration?
An aliquot is a volume of solution at a known concentration, so the two are connected through concentration maths.
