Antifoam system
Use this option to check the level of antifoam remaining, and to test that the antifoam injector system is
working. This option is useful to purge the system before an extended stand-by (several weeks) or when
performing start up procedures.
Injection number Enter the number of injections.
Follow this procedure:
1.
An antifoam priming beaker is available from the spares kit delivered with the instrument. Place this
on the ultrasonic base of the instrument, using the lasers to center it and lower the plastic front door.
2. Activate the motor to lower the instrument head, allowing the needle to penetrate approximately to
the center of the beaker (illustrated below). Refer to Manual displacement above for details on
lowering the instrument head.
3. Press the Start injection button and you should hear the injector working. You should hear as
many clicks as you have defined for the injection number. In addition, the liquid should be seen
exiting from the tip of the needle.
4. On completion of the test press the Stop injection button and raise the instrument head to its home
position. Remove the beaker and rinse well with water. Store with the syringe and antifoam
container for next usage.
