Thanks Rosalie ,
It's just something the Chem teacher has always asked about .They use them for titrations . i think the he also wanted it to show how a more accurate pH reading can be made if you used a specific indicator.

Alice may be able to help you.

Thanks Labbie . I'll ask Alice .Maybe they can increase the allowable file size . The ones that will come through are not much smaller than those that won't .....close , but no cigar

Hello

The colour chart depends on what brand of universal indicator solution you have purchased.

We have the Chem Supply one to match the UL000 range or our Westlab Colour Chart to match our own solution.

Great point Alice . I should have stated that that chart was for Chem supply Universal .

By the way , the stuff you sell covers a larger range .Looks good

For the chem supply universal - you will have to purchase their actual chart since we do not have the pdfs on file.

Appreciate the feedback on our range!
