TF-100 test kit question

[JamesR]

Always thought this was odd, but never asked about it;
The CH test uses 10 drops of R-0010 but it is a tiny 1/2 oz bottle.
The TA test uses just 2 drops of R-007 but it is in a bottle twice the size at 1 oz.
Why does the kit comes with 1/2 the amount of R-0010 when the test uses 5x more drops?

way smaller drops in the R-0010 than the R-007 and can use way more drops depending on how high TA is

The TA test is done very often, or should be, whenever you need to lower pH.

The CH test is done, at most, once a month.

I believe all the dropper tips are the same size for the reagents. That excludes the two indicator agents. The R011L and R0008.

I wondered too, but when I ran out, I ordered a larger bottle from Amazon. Assuming you have Prime, shipping is free. I've rearranged the TF-100 case to accommodate my changes--nice feature of the TF-100 case, plus if you lay down all the bottles facing the same way, you can store the case on one end, and the bottles are all standing up. Or pointing down, if that is your preference.
