water) and swab the test target.
Put the swab stick back into the main tube.
And then put the tip of the tube on your
hand and push the swab stick downwards
to break the capsule in the tube.
Shake the whole reagent tube repeatedly so
that all remaining liquid in the capsule falls
into the reaction tube and dissolves the
reagent in the tube.
• If a disinfectant such as alcohol remains on the surface swabbed, it may interfere
with the measurement. In this case, clean the surface with water or remove the
disinfectant with paper towels before swabbing the surface.
