Strange pH test

[KurtV]

I ran out of the Taylor Phenol Red reagent (R-0014) tonight so I broke out a new bottle. When I tested the pH with that I got a color that didn't match anything on the color comparator; it was a much lighter pink. It's clearly pink but light like the orangey/yellowy colors at the lower end of the pH scale. I ran the test a couple more times with identical results

My pH last night was 7.5 Free chlorine is 3.0 so that can't be having any affect. (Alkalinity is 50 ppm and calcium hardness is 260 ppm; not that those can be a factor here.)

The reagent was purchased this past spring as part of a refill kit from Ben.

Is this just a bad bottle of test reagent?

Thanks in advance for any help.

You might be using the wrong reagent.
R-0004 is used in the Taylor 2000 series pro test kits. (Bens too.)
R-0014 is used in Taylors 1000 series residential kits which have a cheaper comparator.

Hope this helps

you got this one backwards
R-0004 is used in the Taylor K-1000 and Ben's kit (which included a rebranded K-1000) (smalll pH comparator cell)
R-0014 is used in the K-2000 series (K-2005, K-2006, etc.) (Large pH comparator cell and Acid/Base Demand tests)

Sounds like you used the wrong reagent for your comparator!

Guess I've been doing it wrong for years like George.
R-0004 used with the 44 ml comparison tube (Taylor K-2006 & PS-233)
R-0014 used with the small sample tube.
George is right.

Poconos, you beat me to it. When I read Waterbear's reply, I thought he was backwards. Was getting ready to go check just in case my mind was playing tricks on me. You saved me the trouble of getting up and going to look. Thanks!

[KurtV]

Not only didn't I read the numbers on the bottles carefully, I also failed to see that it clearly says which comparator the reagent is for. As you all surmised, I replaced the 0004 with the 0014. What a maroon.

Thanks for the responses.

Thanks Al

I can't believe someone gave me a negative reputation because someone else thought I was wrong! (guess who)
Thanks a lot
Sure doesn't incourage me to post anymore.

Egg on face....typed it wrong. it's the other way around! But I realized what KurtV had done....he had used the wrong reagent for the comparator.

GHM,
Don't feel bad about the negative reputation ---- "That" person did the same thing to me ---- He can't stand to have someone tell him he's wrong. What is even more frustrating is that you can't give him a bad grade, until you attain some sort of "STATUS" you're a nothing. Don't look for me to post any more either (except for this type of thing). I'm a nothing too.

The "reputation" needs to be done away with!!!!
