  • Method for treating indicator fields, indicator field and test device comprising such an indicator field
    Patent number: 11353405
    Abstract: A method for treating a plurality of indicator fields for determining the pH-value of an aqueous solution is provided. Each of the indicator fields contains at least one indicator dye, which is fixed in a non-bleeding manner, in particular on a layer including cellulose or regenerated cellulose, and changes its color within a pH-turning-range. The indicator fields having buffer capacities which differ from one another. All the indicator fields are impregnated from the outside with an impregnation which influences the buffer capacities of the indicator fields in such a way that the deviations are levelled.
    Type: Grant
    Filed: January 10, 2020
    Date of Patent: June 7, 2022
    Assignee: AXAGARIUS GmbH & Co. KG
