Maintenance
There are two versions of the EXO flow cell: EXO1 flow cell (#599080) and EXO2 flow cell (#599201). Flow
rate of the flow cell is typically between 100 mL and 1 L per minute. Maximum flow rate depends on tubing
type, size, and length. Maximum pressure for each is 25 psi.
1 Disassemble flow cell.
To clean the flow cell after use, unscrew and remove the
sonde from the flow cell.
Take apart the flow cell by unscrewing the base from the
locking ring. Remove the flow cell tube by gently pulling
the base and the tube apart. The locking ring will remain on
the tube due to the stainless steel retaining ring.
Repeat the same steps to remove the top of the flow cell
from the flow cell tube.
2 Clean flow cell.
Use water and a mild detergent and water to wipe clean the
flow cell parts.
3 Reassemble flow cell.
Make sure that the o-rings and threads are clean and free of
any particles such as sand, grit, or debris. Apply a thin coat
of o-ring grease or Vaseline to the two o-rings on the flow
cell tube.
Make sure that the o-rings and stainless steel retaining
rings are properly seated on the flow cell tube. Push the
base of the flow cell onto the flow cell tube until it is firmly
seated. This creates the watertight seal.
Screw the locking ring on to the base by turning it
clockwise; do not use a tool and do not overtighten.
Repeat same steps to reconnect the top of the flow cell to
the flow cell tube.
