RoboDis II – The Future of Dissolution Testers

The RoboDis II range of dissolution testers are 100% USP/EP compliant dissolution systems, capable of fully automated dissolution testing of up to 10 batches with USP method 1 (basket) or 2 (paddle). The high-performance system is managed via the 21 CFR Part 11 compliant Disso.Net software. The software controls all functions including the precise robot arm movement as well as all analytical devices including data processing.

Integrated system suitability tests (SST) ensure reliability and easy control. Due to a parallel sampling approach, very short cycle times for measuring profiles can be realised.

The amount of floor space you can save with a RoboDis II 10-batch system is massive. Three complete semi-automatic dissolution testers including media preparation and vessel cleaning can be replaced. Furthermore, the RoboDiss II has a footprint of no more than 2×1 m. With the RoboDis II+ the complete dissolution process can be automated. This way, fully automated testing, including setup, media preparation and automated cleaning process is possible.

24/7 Dissolution Testing

Thanks to the newly developed LED light bar, the water bath can be illuminated at night and allows video capturing without the need of external lights. The LED light bar is energy efficient and offers the perfect brightness for our new USB 3.0 camera system. RoboDis II supports up to 6 of these new cameras which are simply connected to the controlling PC via a USB 3.0 hub.

High Volume Dissolution Testing – New 40 Batch Solution

Our newly developed 40 batch magazine for RoboDis II allows fully automated testing of up to 40 batches of samples. In addition to the 40 batch sample holder, the RoboDis II also gains a 40 batch filter holder. In combination with the LED Light bar, RoboDis II is now able to continually test samples 24/7.
