1. |
Wet the stain with 2
drops of the liquid from one of the
bottle and let
the liquid soak into the
fabric. |
|
This liquefies the
biological material in
the suspect stain so
that it can be extracted
from the garment for
testing. |
|
2. |
Hold one of of the five
blotting papers down on
the wetted stain for 60
seconds or until the
paper is fully wetted
and then set the paper
aside to dry.
|
|
This transfers the
biological material from
the garment to the paper
thereby eliminating any
possibility of staining
or damaging the item
being tested. There are 5
round 70 mm blotting
papers in each kit.
These specialized papers
can be cut into 4 pieces
each to perform
even more tests. |
|
3. |
Using the supplied
dropper place 10 ml of
the same liquid from
bottle into bottle
with powder and then shake
for 60 seconds. |
|
This is very easy to do
and the result will be
half an ounce of the
CheckMate reaction
component in bottle
with powder which is enough
to test about 20 stains. |
|
4. |
Now use the dropper to
put 2 to 3 drops of the
mixed CheckMate reaction
component onto the paper
where you transferred
the stain and read the
results. |
|
The idea in this part of
the test is to saturate
the entire paper all at
once by putting 3 big
drops of the reaction
component onto the
paper. |
|
5. |
Semen will be indicated
in 15 seconds or less by
the appearance of deep
purple color on the test
paper as shown above. |
|
When positive the test
will begin to turn
color within 3 to 5
seconds developing into
a very purple color in
15 seconds or less. |
