Taylor Phenol Red R-0014 vs R-0004

[AnnaK]

Does anyone know what is the difference between the two?

The R-0014 came with my test kit and is called "Residential Series". The R-0004 is in the "2000 Series". Both come in the .75 oz size.

I buy refills from Amato Ind. but they don't carry the R-0014. Are the two products interchangeable?

R-0014 is used in a 9 ml comparator, R-0004 is used in a 44 ml comparator, They are NOT interchangeable!

Doesn't the 0014 have chlorine neutralizer as well?

[waterbear]

They both have chlorine neutralizer in them. The difference is the size of the comparator they are used with (and therefore, the concentration). This is why they are not interchangeable. The color chips on the comparator are calibrated for the reagent they ar designed for. You won't get accurate readings (or even readable colors!) if you switch the reagents.

Thanks for the clarification.

AHA! MOMENT.

I have the Taylor FAS-DPD Service kit, and I always wondered why my "new" pH reagent looked pale, and very difficult to read---crap.

I should be using R-0004, huh? I'm about 95.5% sure the bottle I've been using is the R-0014. Man, the little details will get ya every time.
