When making a solution, the process is quite similar, but the mold installation
changes for the following:

the glass disks. Important: They may still be very hot, depending on the
mold weight and program parameters.
IMPORTANT: Before attempting to make solutions, it is important to remove
the middle section of the mold holder, which can otherwise interfere with the top
of the beakers.
IMPORTANT: Katanax does not recommend attempting to prepare solutions in
a fluxer not fitted with the optional solution magnetic stirrers.
9.1 Fill PTFE beakers with about 100 ml suitable dilute acid. (Nitric acid is the
most commonly used.)
9.2 Add magnetic stirring bars.
9.3 Press the "load beaker" button to slide the platinumware
holders back, against the furnace door.
9.4 Put the beakers on the agitator, in their respective holes.
9.5 Optionally, press the "load beaker" button again, to
move the platinumware holders to the front and clear
