Digital DT 9510 Series Dissolution Tester

High volume dissolution testing with up to 14 test stations


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.

Key Features

Embedded-PC Technology, Modern User Interface, Upgradeability and the AirLift System

  • Digital embedded technology

    The digital embedded PC technology offers all advantages and unlimited possibilities of modern software programming making the DT 950/DT 9510 is more future-proof than ever before. In the first step, this means simple network printing and a modern user interface. In the future, the DT 950/DT 9510 Series will be expanded with additional functions and can thus constantly adapt to the user‘s requirements and future industry 4.0 developments.

  • Modern user interface with TestAssist

    The new, modern user interface of the DT 950/DT 9510 focuses the user on the most important function of the DT 950/DT 9510 - dissolution testing.

    • TestAssist, the intelligent guide for dissolution testing
    • DirectHelp, help directly on the screen with the tap of a button
    • Multilanguage operation in English, French, Spanish, Russian, Chinese and German.
  • Upgrade your DT

    The newly developed hardware of the DT 950/DT 9510 Series enables step by step upgradeability from a manual dissolution tester to a semi-automatic Online-, Offline- or On-/Offline system.

    • Upgrade up to 8 test stations
    • Optional, automatic tablet drop
    • ASS-9 automatic sampling station
  • AirLift System

    With the DT 9510, we are introducing the AirLift system. With the help of AirLift, we enable easy raising and lowering of the huge dissolution head of the DT 9510.

    But AirLift does not simply raise and lower the head, it is also extremly safe to use, thanks to it's two-hand security system. With one hand, the operator pushes one of the two buttons on the right side to select either downward or upward movement. With the other hand, the operator confirms by pulling on the unlocking-lever right in front of the touch screeen. Whenever one of the two buttons is released, AirLift instantly stops. It's highly intuitive, without compromising the safety of the operator.

Network Printing explained

Network printing explained

DT 950/9510 can print to LAN network or USB printers

The technology platform of the DT 950/9510 allows convenient use of network printers from many different manufacturers. Thanks to a practical printer setup, the LAN-connected DT 950/9510 finds all printers in the network. Then all that remains is to select the right driver from a list and the DT 950/9510 prints via the selected printer without any problems.

The DT 950/9510 can currently print on network and USB printers from Hewlett-Packard, Kyocera and OKI. The DT 950/9510 also supports USB printers from Brother. More printers coming soon.

DT9510 Side Low

Our world is turning faster and faster - this is why we designed a dissolution tester that is ready today for the challenges of tomorrow. The DT 9510 can be upgraded even after the initial purchase - even from 12 to 14 test stations, with an automatic tablet drop or an automatic sampling station. The high degree of modularity means that, for example, a 12-station stand-alone DT 9512 can be transformed into the heart of a complete dissolution HPLC On-/Offline system with 14 test stations and Disso.NET 4 software within a very short time. This means that the DT 9510 remains flexible throughout its entire instrument cycle - because who knows now what challenges we will be facing in a few years?
