NanoGenizer-Quad (Quad Pump)

Air Blocking
Symptom: there is no pressure and no sucking from inlet
Prevention: do not run with empty inlet
Reason: there is air inside the pump
Solutions:
1) In the customer setup, press the “Degas” button.
2) Running 50mL water with 50% speed
3) Push the ball into the inlet valve with a pin

Chamber Blocking
Symptom: overload of the pressure
Prevention: pre-treat the sample carefully; reduce the speed
Reason: there are aggregates or particles in the sample; too high a speed
Solutions:
1) Reverse flow the outlet valve with 100mL water with low speed
2) Reverse flow the chamber with water from low to high speed

Overload
Solutions:
1) Reduce the speed and close the power, wait 30 sec and restart
2) Wash with water or solvent
3) Run with clean and homo-disperse sample

No Response
Symptom: the equipment does not respond when click the “Start” button on the touch screen
Solutions: 
1)Turn off the power supply and wait for 30 sec to restart
2) If there is still no response, please check the power input. The power supply of the equipment is 220V. When the external power supply is 110V, a power converter shall be used. And its INPUT port should connect to 110V while the OUTPUT port connect to 220V

Air blocking rarely causes damage to the NanoGenizer; however, the chamber blocking is harmful to the pump because of overloaded pressure in an instant.
1) Pretreat the sample carefully, and always use a clean and homo-disperse sample
2) Adjust the pressure from low to high
3) For safety, do not point the inlet or outlet of high pressure devices and equipment supplied by Genizer, including high pressure homogenizer, extruder, interaction chamber and valve, to any personnel or object that may affect safety or induce property loss.

Tips:
For facilitating the user applications, the two ports in the high pressure cylinder of the NanoGenizer are exchangeable for inlet and outlet.
