Digitaalinen DT 950 sarjan dissoluutiolaite
The ERWEKA DT 950 Series is our first digital dissolution tester on the market, equipped with the most advanced technology for the requirements of today and the challenges of tomorrow.
With state-of-the-art embedded PC technology, the DT 950 is the first of its kind. The 7″ touch display with a modern user interface focuses the user on the most important task the DT 950 has to fulfill – 100% USP/EP/JP compliant dissolution testing, without distractions and errors. For this purpose, we have designed the ERWEKA TestAssist, an intelligent helper that guides the user step by step through the con-figuration of the dissolution test, provides assistance and makes sure that only compliant parameters can be entered.
In addition to the modern user interface, the DT 950 is completely future-proof. With our „Upgrade your DT“ programme, it can be upgraded at a later date – e.g. from 6 up to 8 test stations, with an automatic tablet drop or an automatic sampling station, if the DT 950 is to be upgraded to a dissolution system at a later date. A switch form low-head to high-head mode is also easily possible at all times. Thanks to the advanced embedded system, software functions for the touch display can also be added later.
With all these innovations, however, we have not lost sight of the most important thing: The DT 950 Series are 100% USP/EP compliant.

Digitaalinen DT 9510 sarjan dissoluutiolaite
The ERWEKA DT 9510 Series is the bigger sibling of the digital DT 950 Series dissolution tester.
Controlled by the same embedded PC, every component of the DT 9510 is focused on reliable, high volume digital dissolution testing: The test stations (up to 14) are driven by a single, powerful motor and the big waterbath holds the temperature stable due to the thermal inertia of water. This ensures that parallel testing of two batches of samples can be done at precisely the same conditions, making comparsion between the two as reliable as possible and 100% USP/EP compliant.
With the new optional AirLift system, the dissolution head of the DT 9510 can be simply raised and lowered by the press of two buttons. Furthermore, DT 9510 Series has the same features as it‘s smaller sibiling – digital dissolution testing is done with the help of the latest version of the testing assistant TestAssist and samples can be automatically dropped into the vessel by the optinal automatic tablet drop.

Automaattinen dissoluutio järjestelmä RoboDis II+
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.
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 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.
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
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
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.
