With the ERWEKA RRT 10, automatic dissolution tests for various extended and sustained release dosage forms are now easier than ever before. This device is perfectly suited to simulate the pH changes within the human body. By placing different media in each row, the device mirrors the different gastrointestinal conditions of the body in vivo.
An automatic sample transport between rows enables reliable extended or sustained release testing of different dosage forms in different pH zones. The easy-to-program RRT 10 is therefore the perfect device for changing the pH of multiple media for IV / IVC testing and dissolution profiling of a variety of prolonged release dosage forms (e.g. tablets, coated tablets and oblongs).
The RRT 10 complies 100 % with USP / EP / JP standards and is available either as USP method 3, USP method 7 or as a combination device of both USP methods. It is equipped with an external flow-through heater that minimizes vibrations on the device. In addition, the device offers a mobile touch display that is easy to operate and enables convenient control.
The vessels are housed in an acrylic water bath with an outlet valve for easy cleaning, and the RRT 10's automatic cover system reduces evaporation of the media.
