Removing the reflux/flushback module
You can only remove the reflux/flushback module from the
rack, after you have turned off the shaking motion. Before
shaking motion of the Syncore basic unit stops, you must
make sure that the temperature of the samples is clearly
below the lowest boiling point of the solvents/reagents
used.
If a lower cooling medium temperature was used, conden-
sation water is expected on the reflux /flushbackmodule.
In this case, you should carefully move the reflux/flushback
module upward over the sides of the vessels, because
otherwise water drops will fall into the reaction vessels. If ne-
cessary, you can also remove the vessels from the rack first,
making it impossible for water drops to get into them.
Maintenance of the reflux/flushback modules
The cooling medium tubes to and from the reflux/flushback
modules should be examined once a month for attrition,
leaks and porous sites.
If non – deionized water is used to cool the reflux/flushback
module, you should periodically decalcify the cooling me-
dium path in the module (check annually, in case of daily
use every 6 months, if water contains lots of lime, every
three months):
• Using a syringe, inject diluted acetic acid, formic acid
or citric acid solution (10%) into the reflux/flushback
module via the cooling medium tube.
• Allow to react for 1 hour.
• Rinse thoroughly with water.
The reflux/flushback module cannot be taken apart.
