7 Maintenance of NucleoCounter® NC-250™
7.1 Cleaning
7.1.1 Instrument enclosure.
Depending on the environment in which the NucleoCounter® NC-250™ is operated, it is
suggested that regular cleaning of the enclosure is carried out. When cleaning the
enclosure 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® NC-250™ as this might damage the surface. Cleaning of
the enclosure on a daily basis can be performed by using a mild detergent.
7.1.2 Sample tray
When cleaning the sample tray, great care must be taken against introducing any liquid or
dust into the NucleoCounter® NC-250™. Any liquid that enters the interior of the
NucleoCounter® NC-250™ can damage the optical parts and thus compromise the quality
of the cell counts.
The black surface of the sample tray is anodized aluminum and can therefore be wiped off
with a clean, dry and dust free cloth that reduces fiber contamination of the sample tray.
The sample tray and the optical parts inside the NucleoCounter® NC-250™ should be
properly protected against dust and other contaminants. Therefore, great care must be
taken to ensure that the sample tray is inserted when the instrument is not in use. If the
black surface of the sample tray becomes contaminated it should immediately be cleaned
with a clean, dry and dust free cloth.
7.1.3 Removal of dust particles
An optical window is placed in the sample tray. Please ensure that this is kept clean at all
times. In case cleaning of the window is needed, then refer to the Cleaning kit
NucleoCounter® and follow the instructions here (ChemoMetec Part no: 911-0013).
