Repeat for the other phials as required noting
that a maximum of 6 samples can be dried at a
time.
Set the temperature controller on the Polymer
Drier to 170ºC, switch the drier on and wait for
15 minutes for the drier to reach this temperature
and stabilise.
Start the vacuum pump by pressing the Vacuum Power switch on the front of the polymer drier.
Place each phial into the storage area at the sides of the polymer drier then push each of the metal
tubes into a quick release connector along the top of the drier. Note that the tube clicks into place in
the connector and cannot be pulled out again until the release lever is pressed.
Open each of the vacuum valves SLOWLY, by turning the lever until it is in line with the vacuum pipe,
so that powder is NOT drawn up the plastic tube by the initial vacuum.
Wait for 5 minutes to ensure that a good vacuum is applied to the samples then place each of the
phials into the heated block. This is to ensure that the polymer is not initially heated when air and / or
moisture is present in the tube.
The samples MUST be dried for a time period of 50 minutes (IV < 0.7) or 55 minutes (IV > 0.7).
If the timer is to be used, press the START button on the front of the polymer drier. The light in the
top left hand corner of the timer will light.
A buzzer will sound at the end of the timer period (if the timer was used). Press the RESET button to
stop the buzzer.
At the end of the drying time, remove the phials from the heated block and place in the storage areas
at the sides of the polymer drier.
WARNING: Hot tubes! Wear heat protective gloves when handling phials.
