4. Scintillator Pump
41
As soon as the liquid gets into the syringe without any bubbles, switch
off the pump and place the liquid container on a lower level than the
pump head while the syringe is still set. The underpressure created in
the supply line automatically closes the inlet valve, so that the supply
line (even with turned off pump) remains filled.
Pull the syringe
– with in-take motion – from the valve to drain off pos-
sible residues or spilled liquid.
Screw the supplied 60 cm long stainless steel capillary (ID 0.5 mm) with
pre-installed connection onto the outlet valve. The pump is ready for
operation.
b) New aspiration by scintillator pump
This procedure takes up more time and requires wet valves.
The arrangement is the same as described under a):
The liquid container is set on a higher level than the pump, the supply
line is connected, the outlet not yet.
Switch on and start the pump.
As soon as the liquid has reached the outlet valve and flows without
bubbles, turn off the pump and place the liquid container on a lower
level, so that the inlet valve is closed by the underpressure created.
Screw the outlet line onto the outlet valve, as described above.
