Adjust the length of the telescoping fill-
ing tube to the bottle height and attach
it. Insert the recirculation tube with the
opening pointing outward (Fig. 3).
Note:
With readily crystallizing media, e.g.
alcoholic KOH, the length of the tele-
scoping filling tube should be adjusted
to a distance of approx. 20 mm from the
bottom of the bottle.
Screw the instrument (GL 45 thread)
onto the reagent bottle and then align
the titrating tube with the bottle label.
For bottles with other thread sizes, select
a suitable adapter. The titrating tube can
be adjusted by 70 mm both horizontally
and vertically (Fig. 4).
Note:
The adapters supplied with the instru-
ment are made of polypropylene (PP),
and can only be used for media which do
not attack PP (see 'Accessories',
page 62).
When mounted to a reagent bottle,
always carry the instrument as shown
in the figure (Fig. 5) and always store it
in the upright position!
