STERILIZATION AND DISINFECTION
The centrifuge is finished with acrylic baking enamel on most
surfaces (see
SPECIFICATIONS
in Section 1). Ethanol (70%)
1
may be used on this surface. See Appendix A in
Rotors and Tubes
or publication IN-175 for chemical resistances of centrifuge and
accessory materials.
While Beckman Coulter has tested ethanol (70%) and found that it
does not damage the centrifuge, no guarantee of sterility or disinfec-
tion is expressed or implied. When sterilization or disinfection is a
concern, consult your laboratory safety officer regarding proper
methods to use.
REPLACING THE AIR FILTER
Check the air filter regularly and replace it about once a year, or more
often if it looks dirty. The air filter is not fastened to the centrifuge, so
no tools are required for removal or installation.
1. To remove the air filter, hold the side edges and lift the filter
straight up until the bottom edge is above the centrifuge bottom
retaining strip. Pull the filter out, bottom edge first, and discard it.
2. Install a new filter (885218). The filter has a directional arrow on
one of its edges; install the filter with this arrow pointing toward
the centrifuge. Holding the filter by the side edges, insert the top
half behind the frame edge and lift up until the bottom half clears
the retaining strip. Then set the bottom edge down.
