End Point Detection status
– Shows the current status for each flask.
The status will be one of the following: ON, OFF or COMPLETE.
Touching the end point detection cell for any given flask will allow you
to turn the end point detection ON/OFF. The End Point Detection
status will display COMPLETE automatically when an End Point
Detection alert is achieved for any given flask.
Offset from Ref. Vacuum
– This allows the user to determine the level
of dryness at which the system will declare that the primary drying end
point has been reached. The offset from Ref. Vacuum represents the
difference between the Reference vacuum sensor and the individual
flask sensor. This value can be set from 0.010 to 0.050 mbar (0.010
being the most dry & 0.050 being the least dry).
END POINT DETECTION INDICATES THE END OF THE PRIMARY
DRYING PHASE. SOME SAMPLES MAY REQUIRE ADDITIONAL
FREEZE DRYING TIME (SECONDARY DRYING PHASE) TO
ACHIEVE THE DESIRED MOISTURE CONTENT.
