Fully Automated Dissolution System

Small footprint, great results.

Disso.NET

Three complete semi-automatic dissolution testers including media preparation and vessel cleaning - this is the amount of floor space you can save with a RoboDis II 10-batch system, which has a footprint of no more than 2x1 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.


Our Innovation

Our Innovation

RoboDis II - unique & fully automated.

RoboDis II is the only parallel-working, fully automated dissolution test system currently on the market. All stages of the dissolution processes are computer-controlled and therefore carried out entirely without user intervention. The key element of the fully automatic system is the Disso.NET software developed by ERWEKA, which handles all system functions, including the precise movement of the robot arm, control of the analytic devices, data processing and full documentation.

In the standard configuration, RoboDis II tests up to 10 batches in accordance with USP methods 1 (Basket) or 2 (Paddle). The parallel sampling approach enables very short cycle times for recording of detailed drug release profiles to be selected by the user. Integrated System Suitability Tests (SST) and video monitoring ensure a high degree of reliability. Like all ERWEKA products, RoboDis II is fully USP/EP/JP compliant.

Not smarter, but more reliable

Innovative RoboDis II safety systems.

  • Safety Systems

    RoboDis II Safety Systems

    RoboDis II performs routine tasks more precisely than any human operator – but without a human operator all its powerful fully automatic features would be worth nothing. It is the human operator who defines the test methods, checks results for plausibility and interprets the data obtained. To enable him or her to focus on these tasks, we have equipped RoboDis II with a number of safety features.

  • System Suitability Test

    System Suitability Tests

    In each individual process step, RoboDis II self-checks by means of integrated System Suitability Tests (SSTs). Several built-in light barriers validate the steps performed by Robo Dis II, thus preventing false starts.

  • Documentation

    Full Documentation

    Each step of the test is logged in accordance with the industrial standard 21 CFR Part 11. This will enable you to check, for example, whether RoboDis II actually did test all 40 batches completely over the weekend.

  • High-quality system components

    High-Quality System Components

    RoboDis II is built with tried-and-tested, reliable system components, amongst them, e.g., ERWEKA’s maintenance-free PVP pump and the robot arm made by the internationally renowned pneumatics manufacturer Festo. The use of premium components guarantees maximum precision and lowest downtimes.

  • Video Recording

    Video Recording

    RoboDis II optionally records the entire dissolution process with six integrated video cameras. This allows validating the entire test upon completion, or overlaying the dissolution curve on a time-lapse video recording. Thanks to the LED light strip the water bath can be illuminated at night, allowing 24 hour video recording without the need for external lighting.


Disso.NET

Disso.NET

The key element in the RoboDis II system.

RoboDis II is controlled fully automatically by its integral controller equipped with the Disso.NET software. Designed by ERWEKA specially for the purpose, the Disso.NET-Software constitutes the key element of the RoboDis II system:

A user-friendly editor enables the required dissolution test methods to be defined and started. Disso.NET then manages all steps of the dissolution process from media preparation through to analysis. The software also controls the precise movement of the robot arm and the connected analytical devices. Disso.NET logs all test results and times, and automatically creates an audit trail. Upon completion of the test, the software generates extensive reports and enables export of all test results. In addition, the software controls the System Suitability Tests and the video recording functions.


Overview

Real 24/7 testing

Human-error proof.

Thanks to the newly developed LED light strip, the water bath can also be illuminated at night and thus allows 24 hours video recording without the need of external lights. The LED light bar is very energy efficient and offers the perfect brightness for our 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 already established Ethernet network connection inside the RoboDis II.


New 40 Batch

New 40 batch solution

Perfect for high volume testing.

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 offers a 40 batch filter holder. In combination with the LED Light bar, the RoboDis II is now able to continually test samples 24 hours/7 days a week.


The robotic arm

The robotic arm

Central to RoboDis IIs testing procedure is our advanced, pneumatic robot arm. This arm assembles all samples, adds and removes filters and is even responsible for filling and cleaning of the vessels, saving the operators tremendous amounts of time for doing those repetitive tasks.
