Compact disintegration testing

The ERWEKA ZT 120 light series is the perfect entry-level disintegration tester with one or two motor driven USP/EP/JP compliant test station. The compact unit of our light series is equipped with an integrated flow-through heater and a moulded one-piece PET water bath (no leaking / breaking, easy to clean) with cover.

The ZT 120 light series can be easily operated via a membrane keypad. Defined test run parameters such as run time and water bath temperature are entered with symbol keys and the actual values are then shown on large and bright LED displays. The run-time counter automatically starts as soon as the basket rack assembly is lowered into the test media.


On the ZT 320 disintegration testers series, the test stations (one to four) are driven individually. In order to guarantee outstanding quality and the highest ease of use each test station is controlled by its own keypad. 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 preset run time or when the stop button is pressed, the basket rack is raised from the media to prevent further disintegration of the samples (optional).

The temperature displayed on the LED 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 three 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 automatically raised on completion of the preset run time or when the stop button is pressed. All recorded test run parameters can be hard copied via the USB printer interface. The actual disintegration time can be added manually afterwards.

Automated disintegration testing

The ERWEKA ZT 730 Series with cable-free AirBasket automatically determines the disintegration time of samples by using a unique system of magnets and sensors. The ZT 730 is available with one (ZT 731) or two (ZT 732) individually driven test stations and is equipped with an integrated flow-through heater.

Its newly designed, cable-free AirBasket makes disintegration testing with automatic determination of the disintegration time as easy and fast as possible. Its electronics compartment is sealed, making it dishwasher proof. It‘s sensors are also highly durable and enable the AirBasket to be used in acidic media. AirBasket is available as type A basket with 6 test tubes for standard tablets, or type B basket with 3 test tubes for bigger tablets (according to USP/EP standards).

The reliable waterbath technology utilizes the thermal inertia of water to create a steady temperature for testing according to USP/EP standards. Its temperature sensor PT 100 allows constant control of the waterbath temperature. The ZT 730 series is controlled through an intuitive 7″ touch-screen and is capable of storing and retrieving up to 200 products/methods with results and parameters.
