ABSTRACT:
A device for quantitative analysis of fluids which consists of a rigid, transparent tube containing a predetermined quantity of reagent and end-point indicator, evacuated and fitted with a valve which is suitable for sealing and for precisely controlling the entry of sample fluid so that upon immersion of the valve in the sample fluid and opening and closing it as desired, a quantity of sample fluid may be introduced to the tube and mixed with the reagent contained therein which is precisely the amount necessary to cause a visible change indicating complete neutralization of the reagent. The amount of material being analyzed for can then be ascertained by measuring the amount of sample fluid introduced and applying a simple mathematical formula.
