Use the blotting paper to ab-
sorb any excess liquid from
the washer.
Note: Use the blotting pa-
per gentle and do not come in
contact with the SERS-surface
as there is risk of removing the
solution from it.
After cleaning the washer very
gentle please confirm that there
is remaining solution on the
SERS surface by visual obser-
vation.
Let the sample rest. We recom-
mend for at least 60 sec-
onds and more.
