ZT 720 Series

ZT 720 Series

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 100 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.
