5.3 Result presentation
Depending on the type of analysis performed the result will be present ed on the PC within
a few seconds and the fluorescent image(s) will be stored on the hard disk. Typical process
time is from 20 seconds to 2 minutes for multi image and bi-color analysis.
5.4 Protection of the optical system
The lid covers the sample tray. 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 spring loaded so it will automatically close during insertion of
the sample tray.
Unless inserting or ejecting a sample media or cleaning the sample tray, the sample tray
should be inserted at all times to protect the optical system of the NucleoCounter® NC-
250™. After operation, shut down the NucleoView™ NC-250™ software first, so the sample
tray will be inserted in case left ejected. Then the NucleoCounter® NC-250™ can be turned
off by removing the DC power plug or disconnecting the wall outlet.
