7 Maintenance of NucleoCounter SP-100
A regular cleaning of the NucleoCounter SP-100 is recommended in order to protect its
surface and assure the quality of the collected images.
Depending on the environment in which the NucleoCounter SP-100 is operated it is
suggested that regular cleaning of the cabinet is carried out. When cleaning the cabinet
it is recommended to use a soft moist cloth and gently wipe the surface. Any
contamination, which does not come off immediately, should be rubbed gently with a
cloth wetted with mild detergent. Never use organic solvents or aggressive detergents
to clean the exterior of the NucleoCounter SP-100 as this might damage the surface.
The cassette insertion area and the optical parts inside the NucleoCounter SP-100 should
be adequately protected against dust and other contaminants. Therefore, great care
must be taken to ensure that the lid covering the SP1-Cassette insertion area is closed
when SP1-Cassettes are not being loaded into or removed from the NucleoCounter SP-
100. If the insertion area becomes soiled it should immediately be cleaned with a clean,
dry and dust free cloth.
Always replace the small lid (if such is used, see Figure Figure Figure Figure 59 59 59 59 )
with the large lid when a measurement session is over.
When cleaning the cassette insertion area, great care must be taken against
introducing any liquid or dust into the insertion slit of the NucleoCounter SP-100.
Any liquid that enters the interior of the NucleoCounter SP-100 can damage the
optical parts and thus compromise the quality of the cell counts.
An object on the surface of an optical component can influence the collected image. A
contaminant will normally be visible as a faint object in the image. Since it is also
possible that such contamination is on the surface of the SP1-Cassette,
only objects,
which are stationary in all images, are possible contaminations of the optical
system
. An example of a relatively large contamination is given in Figure 68 .

cloudy phenomena in the upper right hand corner. If the contamination is
stationary it should be removed using compressed air.
