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.
