cloudy phenomena in the upper right hand corner. If the contamination is
stationary it should be removed using compressed air.
7.1.3 Removal of dust particles
The presence of a contaminant (e.g. dust particles) will normally not influence the
counting of cells. The NucleoCounter will distinguish between cells and contaminants,
since cell is generally significantly smaller than contaminants.
Dust and other contaminants deep inside the insertion slit should be removed
using dry, compressed air (see Figure 27).

container in a horizontal position and preferable do not use it at an angle greater
than shown in the figure.
