Changing Fluid Filters
BD Biosciences recommends changing the fluid filters every 3–6 months, or when
increased debris in an FSC vs SSC plot indicates that the sheath filter needs to be
replaced. Spare filters are included with the accessory kit.
1 Remove the filter by pressing the tabs on each quick-disconnect coupling.
2 Install the new filter and connect the quick-disconnect couplings.
Tip Write today’s date on the filter so you will know when to replace it.
3 Open the bleeder valve on top of the filter and leave it open until fluid seeps
out through the valve.
4 Close the valve.
5 Wipe up any excess fluid that might have dripped onto the fluidics cart.
