Shaking
It is possible to treat multiple sample vessels with di
ff
erent
fl
uids at the same time.
Caution
When treating small quantities of combustible
fl
uids in sample vessels, the
country-speci
fi
c guidelines/regulations that are currently in e
ff
ect are to be
observed!
Remove any air bubbles below the vessels.
Caution
There is a risk of being crushed between the tank edge and roller carriage after
switched on!
Step 1:
Fill the ultrasonic bath and degas it
Check that the oscillating tank is
fi
lled with water and a suitable preparation to reduce
the surface tension (contact liquid), please refer to the user instructions of the ultrasonic
bath.
Step 2:
Insert objects to be treated
Before every sonication it is necessary to check whether the
contact
fl
uid needs to be cleaned or replaced.
The laboratory
fl
asks can be secured in the roller carriage with
EK holding clamps, see chapter 7.1.
Equip the roller carriage with laboratory
fl
asks.
The laboratory
fl
asks must be immersed at least 2 cm deep in
the contact
fl
uid. Ensure the oscillating tank is 2/3 full.
The
fi
ll level of the oscillating tank must always be at or slightly
above the
fi
lling level mark following equipment. A low
fi
ll level will damage the
ultrasonic bath!
Step 3:
Power setting
Set the knob for power setting to the lowest setting, see Section 3.2.
Check that the movement does not make any sample
fl
uid come out of the
laboratory
fl
asks. Only then should you start the ultrasonic bath in accordance with
the user instructions.
Caution:
When working with aggressive preparations/sample, if splashes fall in the contact
fl
uid or on the stainless steel surface: change the contact
fl
uid immediately if
necessary, clean the surfaces and wipe dry.
Step 4:
Time setting
Set the required shaking period, see Section 3.1.
Set the required sonication period at the ultrasonic bath and start the ultrasound, see
separate user instructions.
