Use of powder packs Some test sets contain reagents readily dosed as powder in small
packs. Use the powder packs as follows:
 Hold the powder pack in a vertical position
as shown in the picture (perforation up)
and hit it slightly against a solid base so
the powder collects in the lower part.
 Cut open the pack (tear if necessary)
along a horizontal line, starting at the per-
foration.
 Slightly press the pack from both sides so
that a wide opening forms.
 Empty the pack completely. For narrow
vessel openings use a suitable funnel top.
