        BioDis RRT 10

        With the ERWEKA RRT 10, automatic dissolution testing of different extended and sustained release dosage forms has become easier than ever before. This unit is perfectly suited for simulating the pH-changes within the human body. By placing different media in each row, the device echoes varying in vivo gastrointestinal conditions of the body.

        An automatic sample transport between the rows allows the reliable testing of the extended or sustained release from different dosage forms in various pH-zones. The simple to program RRT 10 thus, is the perfect unit for multiple media pH-changes for IV/IVC testing and dissolution profiling of a variety of release dosage forms (e. g. tablets, coated tablets and oblongs).

        Overview 2

        100 % USP/EP/JP compliant

        and controlled by touch

        The RRT 10 is 100 % compliant to the USP/EP/JP standards and available as either USP method 3, USP method 7 or as a combination device of both USP methods 3 and 7. It comes with an external flow-through heater, which minimizes vibrations to the device. Moreover, the unit offers a mobile touch display, which is easy to use and provides convenient control.

        Vessels are placed inside an acrylic water bath with an outlet valve for easy cleaning and the automatic cover system of the RRT 10 reduces media evaporation.


        Flexible device for different use cases.

        100% USP/EP/JP compliant
