RoboDis II+ is the only simultaneously operating, fully automatic dissolution test system currently on the market. All stages of the dissolution processes are computer-controlled and are therefore carried out completely without user intervention.
The key element of the fully automated system is the Disso.NET software developed by ERWEKA, which controls all system functions, including precise movement of the robot arm, control of the analyzers, data processing and full documentation.
In the standard configuration, the RoboDis II+ tests up to 10 batches according to USP methods 1 (basket) or 2 (paddle). The parallel sampling approach enables very short cycle times for recording detailed drug release profiles, which can be selected by the user. Integrated System Suitability Tests (SST) and video monitoring ensure a high level of reliability. Like all ERWEKA products, the RoboDis II+ is fully USP / EP / JP compliant.
Three complete semi-automatic dissolution testers including media preparation and vessel cleaning - that's how much floor space can be saved with a RoboDis II+ 10-batch system that requires no more than 2x1 m of floor space. With the RoboDis II+, the entire dissolution process can be automated. This enables fully automated testing, including set-up, media preparation and the automatic cleaning process.

RoboDis II+ performs routine tasks more precisely than any human operator - but without a human operator, all its powerful, fully automated functions would be of no value. It is the operator who defines the test methods, checks the plausibility of the results and interprets the obtained data. To enable the operator to focus on these tasks, the RoboDis II+ has been equipped with a range of safety functions.
In each individual process step, the RoboDis II+ checks itself using integrated System Suitability Tests (SSTs). Several built-in light barriers validate the steps performed by the RoboDis II+, preventing false starts.
Each step of the test is logged in accordance with industry standard 21 CFR Part 11. This, for example, allows for checking whether the RoboDis II+ has fully tested all 40 batches over the weekend.
RoboDis II+ is built with proven, reliable system components. Among these are the maintenance-free PVP pump from ERWEKA and the robot arm from the internationally renowned pneumatics manufacturer Festo. The use of premium components guarantees maximum precision and minimum downtime.
The RoboDis II+ optionally records the entire resolution process with six integrated video cameras. This enables the validation of the entire test after completion or the overlaying of the dissolution curve with a time-lapse video recording. Thanks to the LED light bar, the water bath can be illuminated at night, enabling 24-hour video recording without the need for external lighting.
The RoboDis II+ is operated fully automatically via its integrated controller, which is equipped with the Disso.NET software. The software, specially developed by ERWEKA for this purpose, is the key element of the RoboDis II+ system: the desired dissolution test methods can be defined and started using a user-friendly editor. Disso.NET then controls all steps of the dissolution process from media preparation to analysis. The software also controls the precise movement of the robot arm and the connected analyzers. Disso.NET logs all test results and times, automatically creating an audit trail. Once the test is complete, the software generates comprehensive reports and allows all results to be exported. In addition, the software controls the System Suitability Tests (SST) and the video recording functions.
Thanks to the newly developed LED light strip, the water bath can also be illuminated at night, making 24-hour video recordings possible without the need for external lighting. The LED light bar is very energy efficient and provides the perfect brightness for the new gigabit Ethernet camera system. The RoboDis II+ supports up to six of these new cameras, which are simply connected to the controlling PC using the existing Ethernet network connection in the RoboDis II+.
Our 40-batch magazine for the RoboDis II+ ensures fully automated dissolution test runs with up to 40 sample batches. In addition to the 40-batch sample holder, the RoboDis II+ also offers a 40-batch filter holder. In combination with the LED light bar, the RoboDis II+ is now able to continuously test samples 24 hours a day, 7 days a week.
At the core of the RoboDis II+ testing process is our advanced pneumatic robotic arm. This arm assembles all samples, adds and removes filters and is even responsible for filling and cleaning the vessels, saving operators an enormous amount of time on these repetitive tasks.
Seven USP-compliant test vessels in the RoboDis II+ system support testing in R&D and quality control. In quality control, for instance, six samples can be compared with a reference sample. Alternatively, seven different samples can be tested in parallel in R&D.
The RoboDis II+ is equipped with 6 video cameras and an LED light strip. The water bath can be easily illuminated and the new video capturing capabilities can be used without external lighting. In addition, video recording of the dissolution process is possible in time-lapse mode.
The RoboDis II+ supports the use of both paddles (USP 2) and baskets (USP 1), both of which can be exchanged by the user. It also supports the use of sinkers measuring up to 34 mm. The dropping and removal of sinkers is fully automatic using the sinker tool supplied.
In the version with 40 batches, the RoboDis II+ enables genuine 24/7 testing and is able to process 40 batches without human intervention.
The optional pH measurement permits pH changes according to USP method A (half change) and method B (full change).
Poroplast filters are fitted fully automatically by the robot arm for each test.
RobDis II+ supports integrated online UV-Vis or HPLC analytical devices. The samples are taken fully automatically and transferred to the analyzers.
