Chapter 4: Maintenance 75
Cleaning External Surfaces
To prevent salt buildup, wipe down all external cytometer surfaces that have
been exposed to sheath fluid.
NOTICE Over time, saline deposits may develop on the interior surface of the
SIT Bal seal retainer, causing an incomplete SIT flush between samples. If this
occurs, you might need to remove and clean the retainer with DI water. See
Figure 4-5 on page 80 and steps 4, 7, and 8 of the Replacing the Bal Seal
procedure that starts on page 80.
NOTICE Do not use BD FACSClean solution or bleach to clean or disinfect the
barcode reader. See Cleaning the Barcode Reader on page 48.
Materials

All cytometer surfaces that come in contact with biological specimens can
transmit potentially fatal disease. Use universal precautions when cleaning
cytometer surfaces. Wear suitable protective clothing and gloves.
To prevent damage, do not use isopropyl alcohol or ethanol on any
cytometer or fluidics cart surface.
