HC-110 Question.

If i REALLY have to have an accurate volumetric measurement, I can use a 1.0 mL syringe. it is graduated in 0.01mL units, otherwise, I so like everyone else and round up to the next mL.

I find using various dilutions of a stock solution to be much easier than the syringe approach, personally. Since Rodinal doesn't seem to last long as stock, I use it with a syringe. This is easy, however, because it is really runny, i.e. not a syrup like HC-110.

I have been using a 10mL syringe for Rodinol. For HC110 I usually use a 30 mL enteric syringe. it has a large tip and is easy to use.

Small syringes are available at any agricultural store for dispensing meds to livestock. Cheap too.

First, I transfer the HC-110 concentrate to squeeze bottles or pump bottles that permit me to dispense the concentrate in small amounts.

When I mix the working solutions, I use a 45 ml Paterson graduate.

If I want to use 6 ml of concentrate, I fill the graduate to something like 30 ml, and then add the HC-110 concentrate to the water until the total volume reaches 36 ml.
