Indicators

Chemical indicators are substances that change colour in response to pH changes, temperature, or the presence of specific chemicals. Our range includes universal indicator solution, phenolphthalein solution, methyl orange, and other acid-base indicators for chemistry laboratory use.

Used in titrations, pH demonstrations, and general chemistry experiments, indicators provide a simple, visual way to detect the endpoint of a reaction or determine approximate pH without electronic meters.

SmartLabs supplies chemical indicators to schools and labs across South Africa. Browse our range for reliable, affordable indicators for your chemistry teaching and laboratory work.
