5.17 Inserting and removing the Cassette
When a cassette has been properly loaded with lyzate mixture, as explained in Section
1.1.2 , the cassette is inserted into the NucleoCounter SP-100 instrument.
The grey 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.
To insert the cassette:
1. Flip the lid up
2. Grip the cassette on either side of the piston barrel, but taking care not to
touch the measurement windows (see Figure 58 ).
3. Insert the cassette, bevelled edge down, into the insertion slit
(see Figure 58 ).
After analysis the lid is lifted and the cassette is removed from the insertion slit and
disposed properly according to national or local laws or regulations regarding the nature
of the mixture it contains.
Unless you are inserting/removing a cassette or cleaning the inserting area or the lid,
keep the lid closed at all times.
