3.3 Supplementary cleaning procedures
The CPT-2x is also available in the version "
Oil, grease and silicone-
free
" or cleaning for paint compatible version (LABS). These instru-
ments have passed through a special cleaning procedure to remove
oil, grease and paint-wetting impairment substances (PWIS).
The cleaning is carried out on all wetted parts as well as on surfaces
accessible from outside. To keep the purity level, the instruments are
immediately packed in plastic foil after the cleaning process. The
purity level remains as long as the instrument is kept in the closed
original packaging.
