ZT 320 Series


On the ZT 320 Series disintegration testers the test-stations (one to four) are driven individually. Each test test-station is controlled by its own keypad to guarantee ease of use. After programming the required test-run time the basket rack assembly with its loaded samples is automatically lowered into the media. On completion of the pre-set run-time or when the stop button is pressed the basket rack is raised from the media to avoid the samples continuing to disintegrate (optional).


The temperature displayed on the LE display is the one measured by the standard external temperature sensor either located inside the water bath or the test media. The optional type “B” basket rack assembly with 3 larger test-tubes can be fitted to all ZT 220/320 disintegration testers.


Optionally, the basket rack assembly is moved into the media when the start button is pressed and raised automatically on completion of the pre-set run-time or when the stop button is pressed. The unit comes with external water bath/ media temperature probe. All recorded test-run parameters can be hard copied via the optional USB printer interface; the actual disintegration time is added manually.
