2.2.12.4 Clogging of the Flow Chamber/DIFF Probe
In the case of flow chamber/DIFF probe clogging, you can manually push the probe cleanser to
clean the flow chamber/DIFF probe. Detailed steps are shown below:
1. Pull out the white tube connected to Valve 11 from the flow chamber (while making sure that the
connecting tube has been pulled out correctly). Put the tube into the probe cleanser with a
dilution ratio of 1:3 (probe cleanser to diluent) below the surface of the liquid. Then pull out the
tube connected to connector No.1 of Valve 20 (this tube is the transfer tube for white Teflon tube
1.5 and thin 50 tube, covered with marking ring
3 ), and connect the plastic syringe to the 50
transfer tube through the silicone tube (as shown in Figure 2-27).

2. Press the pinch valve of Valve 12 with the fingers of one hand, and pull the plastic syringe in step
1 with the other hand, to absorb the probe solution into flow chamber. If the absorption resistance
is high, the plastic syringe shall be pulled with hand to hold for a certain time, and release to
enter into the probe cleanser stage after the level of the diluted probe cleanser in small sample
cup is observed to drop.
When pushing the syringe, the pinch valve must be pressed tightly by hand; otherwise the cleaning
effects cannot be reached.
