6 Maintenance of NucleoCounter

Figure 24. An image showing a contamination of the optical system, visible as a white
cloudy phenomena in the upper right hand corner. If the contamination is
stationary it should be removed using compressed air.
6.1.3 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 cells are generally significantly smaller than contaminants.
Use the F50 function (refer to section 5.6 Zero Count Check (F50)) regularly in order to
check for contamination of the insertion slit.
Dust and other contaminants deep inside the insertion slit should be removed
using dry, compressed air (see Figure 25) and if necessary using the
NucleoCounter

Clean Kit (refer to Technical Note No. 004 “How to clean the
NucleoCounter”). Use the F50 function to verify the rinsing effect. If the error
appears even after several attempts to clean the insertion slit with compressed air,
contact ChemoMetec A/S or the local distributor.

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