Colloid Storage
Please follow these procedures when storing
used material that will be re-melted.
1. After removing the colloid from the
duplicating flask, rinse with water to remove
any foreign material clinging to the colloid.
Pieces of gypsum or investment that remain
in the colloid can permanently damage the
tank and/or stirrer, as they will be dragged
around inside the tank during the cook-down
cycle.
2. Gently shake-off excess water.
3. Store colloid in a clean, covered
container. Keep container covered so
moisture is not lost.
4. When ready to cook-down, cut colloid
molds in quarters, then load duplicator.
5. If re-melted colloid is difficult to
dispense due to high viscosity, add small
amounts of water until the viscosity is
reduced.
Changing Duplicating Material
When the tank is virtually empty, press
the red POWER button on the front panel to
turn-off the duplicator. To remove the colloid
at the very bottom of the tank, simply allow
it to cool then peel it out.
Preventive Maintenance & Cleaning
1. Clean Colloid-Saver 3.5 duplicator
approximately once a month or when
new duplicating material is added. Your
frequency of cleaning may vary with usage.
Scrub inside wall of tank and cover assembly
with a non-abrasive pot scrubber.
2. Inspect stirrer for wear and distortion.
Clean with non-abrasive pot scrubber.
3. Remove back panel and inspect the
bearing. If any colloid is leaking from this
area, the bearing must be replaced.
4. Be very careful not to spill liquids on
the duplicator! Liquids can damage the
control panel and circuit boards. If a spill
occurs, unplug the duplicator immediately
and clean thoroughly.
5. Clean fan air filter regularly to maintain
proper air flow.
Calibration
Calibration of the Colloid-Saver 3.5
duplicator is not necessary. The computer
controller is self-calibrating.
Continuous Dispensing (Emptying)
The Colloid-Saver 3.5 duplicator
can be used to fill flasks in a continuous
line using the optional Dispensing
Extender shown in
