Does anyone have a recipe for dilution of universal indicator?

Do you dilute the purchased one? Or use it as is? I'm curious now and am questioning my methodology!

If it is a purchased bottle of universal indicator then I have never diluted the contents. I have decanted into smaller dropper bottles for use in the classroom. I am not prepared to mess with the quality of the product.
What prac requires that the universal indicator needs to be diluted?

We don't dilute the purcased one. Another Labbie here did, but the teachers ended up having to use more and it didn't save anything.
We just decant into dropper bottles.

Years ago about 1999 they use to have printed on the Universal indicator that it needed to be diluted. But then stopped printing it on their bottles.
