Taylor R-0004 Appears Darker Than R-0014

[Michael1]

I bought a bottle of R-0004 thinking it was just a larger version of R-0014. However, I noticed that R-0004 is much darker (showing higher pH) than R-0014. You can see the fluid is darker in the bottle. Did I get a bad bottle, or is there a difference in these products?

I asked Taylor about this some years ago. The 0004 and 0014 are different and not interchangeable.

Different product numbers means different product. Taylor labels different sizes by appending a letter to the end of the product number, such as E for 16 ounces, D for 4 ounce bottles, C for 2 ounces, etc.

R-0004 and R-0014 are not the same.

In my case I can see the color better with the big vial and the R-0014

Thanks for the info on these two reagents. Very helpful! I know better now.
