Definition
role held by a solution that is prepared with an accurately known solute concentration so that measured portions can be diluted to the concentration needed for a particular use
Explanatory Notes
1) A stock solution is usually prepared at a higher concentration than is needed for its later use and is diluted to obtain the required concentration before use. 2) Because the solute concentration is accurately known, stock solutions support reproducible preparation of other solutions, mixtures, assay materials, formulation materials, culture media, or process materials. Measured portions may be diluted or added as components in planned processes. Their reliability depends on correct preparation and appropriate storage conditions, since degradation, precipitation, contamination, or evaporation can introduce concentration errors over time. 3) Dilution of a stock solution may produce a working solution or an intermediate stock solution
Examples
- the stock solution role of a 1 M glucose solution used to prepare lower-concentration glucose additions for cell culture medium; the stock solution role of a 100 mM IPTG solution used to prepare induction solutions; the stock solution role of a concentrated sodium hydroxide solution used for preparation of pH adjustment solutions;

Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
There are insufficient constructs to create a set of necessary and sufficient conditions
Formal Axioms
First-Order Logic Axioms
StockSolutionRole(x) → Role(x) ∧ ∃s (Solution(s) ∧ roleOf(x, s))
Semi-Formal Natural Language Axioms
if x is a ‘stock solution role’ then x is a ‘role’ that is the ‘role of’ some ‘solution’
