Last year when I ran out of R-0009 I bought a .75 oz. size bottle at Leslie's to resupply my TFP-100 kit for that one reagent. I'm still using the 1.0 oz. R-0007 and R-0008 bottles that came with my refill set from the TFP website.
I notice that the drops from the 1.0 oz. bottles of R-0007 and R-0008 seem much larger than the drops from the .75 oz. bottle of R-0009 from the pool store. Yes, I'm wiping the tip of the bottle and they still seem smaller. So I'm wondering if my TA is reading a little high.
Should the drops be the same size from the different bottles? Has anyone heard of a defective bottle tip that produces smaller drops than normal?
