Cleaning Guide: NucleoCounter® NC-250
™
and NC-
3000™
We recommend regular cleaning of the NucleoCounter® NC-
250™ and NC
-
3000™ instruments
to protect
their surfaces and to ensure data image quality.
Cleaning the Exterior
When cleaning the exterior of the NucleoCounter® NC-
250™ and NC
-
3000™ instrument
, use a soft damp
cloth and gently wipe the surface. If contamination does not come off immediately, rub gently with a cloth
moistened with mild detergent. Never use organic solvents or aggressive detergents to clean the exterior of
the NucleoCounter®.
Cleaning the Sample Tray
When cleaning the sample tray, take great care not to introduce any liquid or dust. Any liquid that enters
the interior of the NucleoCounter® can damage the optical parts, compromising the quality of the cell
count. The black surface of the sample tray is made of anodized aluminum and can therefore be wiped off
with a clean, dry and dust-free cloth to avoid introducing fibers to the sample tray.
Always keep the sample tray inserted when the instrument is not in use to protect the optical parts inside
the NucleoCounter® against dust and other contaminants.
Removing Dust Particles
The presence of an object or a particle
(e.g. dust) will not normally influence
counts made by the NucleoCounter®.
The instrument will distinguish between
cells and non-cells, since cells are
generally significantly smaller.
However, the presence of objects on the
surface of an optical component can
affect the visual data display (see Figure
1).
