About Indicators, Papers & Stains
Indicators are reagents used to determine the specified end point in a chemical reaction, to measure hydrogen-ion concentration (pH), or to indicate that a desired change in pH has been achieved.
Chemical reactions and the status of a reaction can be monitored by changes in the color of the indicator.
pH indicators, redox indicators and complexometric indicators are normally used for titration of chemical solutions. pH indicators are frequently employed in analytical chemistry to determine the extent of a chemical reaction.
We offer a variety of stains in powder and as solutions, which are used in clinical applications histology, cytology, hematology, microbiology.
Indicator papers: The acidity or basicity of a solution is defined as the pH. A myriad of commercial protocols for textile, leather, dyes, chemicals, process water and waste water analysis rely on the routine determination of this critical measurement. A color change in an indicator dye can be used to give a pH measurement of a solution. This color change is matched against a color chart to provide the pH value.
