4. Automatic pH Changer,
AMC-A
The AMC-A is a device for the automated pH
change according to USP method “A” (half-
change).
The accurate amount (volume) of buffer solu-
tion is dosed into the 8 glass vessels (max. 250
ml capacity) which are located inside a thermo-
statically heated acrylic water bath.
In combination with the DT 820 where the pH
change time point is set/programmed the op-
eration is fully automated: the stirring action is
stopped and the 8 pumps, integrated into the
AMC-A, transfer the buffer solution from the
AMC-A into the vessels of the Dissolution
Tester. When the pre-set time limit of pH
change is reached (default setting 5 minutes
according to USP) the stirring action is re-
started.
Using any other Dissolution Tester the opera-
tion is semi-automatic. The stirring action has to
be stopped, by pressing a knob at the AMC-A
the buffer solution transfer is started and when
the pH change time limit is reached the stirring
action has to be re-started.
