Operation of the NucleoCounter

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).
