Solvent flush time(s) The Solvent flush time(s) setting determines the amount of time (in
seconds) that the solvent pump will continue to operate after the solvent
chamber has emptied all solvent into the sample vial during a wash. This
allows time for the lines and viscometer tube to be purged of solvent.
Select a value from 1 to 60 seconds for this option. The time will vary
with the pressure setting (miniAV-X right front “ear” panel).
Tube tip soak time(s) The Tube tip soak time(s): setting determines the length of time that the
miniAV-X tube tip will soak in the solvent after the solvent has been
introduced into the sample vial. Select a value from 1 to 120 seconds for
this option. This is the amount of time that will be used for both a solvent
soak and a final solvent “bubble cleaning” following the evacuation of
solvent from the internal solvent chamber.
Final dry time(s) The Final dry time(s) setting determines the additional amount of time
forced air is channeled through the viscometer tube to dry it at the
conclusion of the rinse/dry cycle. Select a value from 15 to 300 seconds
for this option. The time period selected will be added to the preset dry
period of 108 seconds for normal tubes and 36 seconds for fast-run tubes.
Cup Empty Time The Cup Empty Time option determines the amount of time allotted for
evacuation of sample from the sample cup prior to the beginning of the
wash sequence. Select a value from 1 to 255 seconds for this option. The
evacuation time should be adjusted so the highest expected viscosity oil
is evacuated from the cup before the solvent is introduced into the
solvent chamber. Improper adjustment may result in solvent overflow if/
when solvent is evacuated into a waste line that still contains sample
residue.
CAUTION Be careful to consider bath temperature(s) and potential solvent hazards
when selecting solvents for use with the miniAV-X instrument.
CAUTION Make certain to replace the sample vial with an empty vial prior to
raising the vial holder. Otherwise, solvent may overflow.
