There is of course very easy maths behind this, but for your convenience look at this
table as a help:"
Volume method "
If you choose this method you should have a 500-1000ml ”graduated cylinder” or
”volumetric flask” to perform this mixing. If you have not, go for the ”weight
method”. "
We also recommend using a funnel to avoid spilling any
reagent or water. The volume relation between
reagent/RO water should be exact 1/4.
It is advisable to not mix too much at each occasion.
We recommend mixing a maximum 2.5-3 liter each
time. That will last around 8-9 weeks in normal usage. If
you mix larger quantity each time, and maybe do some
slight error, you will regret that.
If you for instance wants to have 2000ml of a ready to
use solution, then pour up exactly 400 ml reagent, and
mix that with 1600 ml RO-water. Always use 4 times
more RO-water than the reagent, thus keep the 4/1
relation, and it will be correct. There is of course very
easy maths, but for your convenience look at this table
