VTK-TR-BA-072e-1 - User Manual MDS 358X Series
Unless the compatibility between the O-ring/Tappet sealing and the solvent is excellent, do not
insert the O-ring/Tappet Sealing into the solvent.
CAUTION
Damage of components
Place tipped nozzle inserts (e.g. J-, C-, N27-type) in a separate beaker. To avoid damage, do not
place tipped nozzle inserts together with other components in one beaker.
IMPORTANT NOTE
Keep heater connection dry
Make sure that the heater connection stays outside the beaker (see picture), to avoid any fluids
reaching the electronics. (In case you do not use a heater and have the mounting body BY
instead of an MDFH, you can ignore this part.)
– Fill the beaker with an appropriate solvent (e.g. Isopropanol), until all of the parts are covered.
– Leave the components for ca. 15 min inside.
High temperature, danger of burns
Be aware of your dispensing medium when setting the temperature, if the dispensing medium is
inflammable. Otherwise, with too high temperatures deflagration might occur. Set the
temperature as low as possible within the effective range.
– Take the beaker with the components out of the ultrasonic bath. Then use tweezers to take
the components out of the beaker.
Next, clean all components by hand.
– For fine purification, you have to clean all components by hand. In general, you should take
special care about those places, which get in contact with the medium or where two different
parts fit together. First, you should clean the nozzle insert, since hardening would cause most
problems here.
