7 Maintenance of NucleoCounter YC-100
A regular cleaning of the NucleoCounter is recommended in order to protect its
surface and assure the quality of the collected images.
7.1 Cleaning
Depending on the environment in which the Nu cleoCounter is operated it is
suggested that regular cleaning of the cabinet is carried out. W hen 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 b e rubbed gently with a
cloth wetted with mild detergent. Never use organic solvents or aggressive
detergents to clean the exterior of the NucleoCounter as this might damage the
surface.
7.1.1 Cassette insertion area
The cassette insertion area and the optical pa rts inside the NucleoCounter should
be properly protected against dust and other contaminants. Therefore, great care
must be taken to ensure that the lid covering the cassette insertion area is closed
when cassettes are not being loaded into or removed fro m the NucleoCounter. If the
insertion area becomes contaminated it should immediately be cleaned with a clean,
dry and dust free cloth.
When cleaning the cassette insertion area, great care must be taken against
introducing any liquid or dust into the inse rtion slit of the NucleoCounter. Any liquid
that enters the interior of the NucleoCounter can damage the optical parts and thus
compromise the quality of the cell counts.
7.1.2 Optical elements
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 cassette, only objects,
which are stationary in all images, are possible contaminations of th e optical
system. An example of a relatively large contamination is given in Figure 26.
