ERWEKA DISINTEGRATION TESTERS

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.

Overview

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 720 series automatically determines the disintegration time of samples by using a unique system of magnets and sensors. It also tests whether or not a sample completely disintegrates.

The ZT 720 is available with one (ZT 721) or two (ZT 722) individually driven test stations, equipped with an integrated flow-through heater. Its temperature sensor PT 100 allows constant control of the water bath temperature. The ZT 720 series is controlled through an innovative 7” touch screen and is capable of storing and retrieving up to 200 products/methods with results and parameters.

Select the basket type for your individual need: Basket type A comes with 6 test tubes for standard tablets, basket type B contains 3 test tubes for bigger tablets (according to USP/EP standards).

Effortless cleaning is easily possible due to the removable acrylic water bath, equipped with an outlet valve. The USB and LAN interfaces ensure simple and easy data export.
