Chapter 4: Maintenance 109
Cytometer Inspection and Servicing
Inspect the following cytometer components at the end of each day and service
them, as needed.
• Sample coupler
Check for leaks around the sample coupler on the cytometer SIT. If
necessary, tighten the top nut to secure the sample coupler to the SIT.
If the coupler continues to leak after you tighten the fitting, remove and
then reinstall the coupler as follows.
- Hold the coupler with one hand while you unscrew the tightening nut
with the other hand.
- When the coupler is loose, pull it straight down.
All cytometer surfaces that come in contact with biological specimens can
transmit potentially fatal disease. Use universal precautions when handling
cytometer components. Wear suitable protective clothing, eyewear, and
gloves.
