5 Operation of the NucleoCounter
5.1 Ready mode
After the NucleoCounter has started successfully the display
should read:
NucleoCounter
Ready
Figure 11. The NucleoCounter is ready for cell counting.
This display is also shown if the “
Esc
” button is activated in
the result mode or any other situation, except during measuring
or shutting down.
5.2 Inserting and removing the cassette
When a cassette has been properly loaded with lyzate mixture,
the cassette is inserted into the NucleoCounter instrument.
5.2.1 Protection of the optical system
The sample compartment lid covers the cassette insertion area.
This lid is designed to protect the area from dust and other
potential contaminants, and to keep external light from
interfering with the fluorescent image recording. The lid is
fitted with magnetic hinges, so it can be easily removed for
cleaning purposes.
Unless inserting/removing a cassette or cleaning the inserting
area or the lid, the lid should be kept closed at all times as
means of protecting the optical system of the NucleoCounter.
5.2.2 Inserting cassette
To insert the cassette:
1. Flip the lid up until it comes to a rest
2. Grip the cassette on either side of the piston
cylinder, but taking care not to touch the measurement
windows (see Figure 12).
3. Insert the cassette, bevelled edge down, into the
insertion slit
(see Figure 12).
