The ERWEKA DT 950 series is our first digital dissolution tester on the market, equipped with the latest 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-inch touch display with a modern user interface keeps the user focused on the most important task the DT 950 has to fulfill - 100% USP / EP / JP compliant dissolution testing, without any distractions or errors. For this purpose, the ERWEKA TestAssist has been developed; an intelligent helper that guides the user step by step through the configuration of the dissolution test, provides assistance and ensures that only compliant parameters can be entered.
In addition to the modern user interface, the DT 950 is also absolutely future-proof. With our "Upgrade Your DT" program, the system can be upgraded at a later date - e.g. from 6 to 8 test stations, with an automatic tablet drop or an automatic sampling station, if the instrument is to be upgraded to a dissolution system at a later date. It is also easy to switch from low-head to high-head mode at any time. Thanks to the advanced embedded system, software functions for the touch display can also be added later.
With all these innovations, however, ERWEKA hasn't lost sight of the most important thing: the DT 950 series is 100% USP / EP compliant.
100% USP / EP / JP Compliant
USP Methods 1, 2, 5 and 6
Intuitive Touch Interface
Upgradeable at Any Time
The digital embedded PC technology offers all the advantages and unlimited possibilities of modern software programming and makes the DT 950 more future-proof than ever before. In the first step, this means simple network printing and a modern user interface.
In the future, further functions will be added to the DT 950 series, allowing it to constantly adapt to user requirements and future Industry 4.0 developments.
The modern user interface of the DT 950 keeps the user focused on the most important function: the dissolution test.
The newly developed hardware of the DT 950 series enables a step-by-step upgrade from a manual dissolution tester to a semi-automatic online, offline or on- / offline system.
The technology platform of the DT 950 / DT 9510 enables the 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. Simply select the correct driver from a list and the DT 950 / DT 9510 reliably prints via the selected printer.
The DT 950 / DT 9510 can currently print on network and USB printers from Hewlett-Packard, Kyocera and OKI. Both systems also support USB printers from Brother. Further printers will follow shortly.
The touch interface of the DT 950 centers the user's attention on the most important task to be performed with the DT 950: dissolution testing. The central component is the TestAssist, an intelligent assistant with real-time feasibility checks, which provides support and ensures that the parameters entered conform to USP / EP / JP. This makes dissolution testing easy and safe.
In addition to the TestAssist, all other features, such as the control panel, the qualification menu or the service menu, are designed to connect users and hardware as quickly as possible.
Testing in 3 Simple Steps
Parametrisation Within Conform Ranges
The touch interface of the DT 950 centers the user's attention on the most important task to be performed with the DT 950: dissolution testing. The central component is the TestAssist, an intelligent assistant with real-time feasibility checks, which provides support and ensures that the parameters entered conform to USP / EP / JP. This makes dissolution testing easy and safe.
In addition to the TestAssist, all other features, such as the control panel, the qualification menu or the service menu, are designed to connect users and hardware as quickly as possible.
Each input field has a quickly accessible help function. If it is unclear what should be entered in the field, the help function can be triggered by clicking on the question mark symbol right next to it. This function is available throughout the ERWEKA OS, so that information can be obtained at any time.
The modern architecture of the ERWEKA operating system supports a wide range of languages (including German, English, Spanish, French, Chinese, Russian, and many more), making the DT 950 the most accessible device ERWEKA has ever developed, anywhere in the world.
The service menu provides the user with direct access to the DT's most important hardware functions and information. The serial number and software version can be quickly retrieved for service cases, and maintenance can be carried out more quickly and efficiently.
Thanks to the new qualification function, qualifying the DT 950 is very easy. Simply call up the qualification menu and follow the instructions.
Our world is constantly changing - that's why ERWEKA has developed a dissolution tester that is already well equipped for the challenges of tomorrow. After the initial purchase, the DT 950 can also be upgraded further - including from 6 to 7 or 8 test stations, with an automatic tablet drop or an automatic sampling station. The high degree of modularity makes it possible to quickly turn a 6-station stand-alone DT 956, for example, into the heart of a complete dissolution HPLC On-/ Offline System with 8 test stations and Disso.NET 4 software. This means that the DT 950 remains flexible throughout its entire life cycle. After all, who knows what challenges await in a few years' time?
The power switch has been moved to the side of the device, making it much easier to reach and operate it. In addition, the power supply has been redesigned to 24 V.
The tablet drop has been moved to the top of the DT head. This means that filling is always immediately visible. The drop can be controlled automatically as an option.
The DT head has been further improved. In addition to mechanical changes to the guide and a new aluminum lock, the weight has also been reduced. This makes it easier to handle the dissolution tester head without compromising its robustness.
The water outlet has been lowered further and also moved to the rear. This way, it does not interfere during the normal use of the dissolution tester. The outlet has also been fitted with a practical quick-release coupling that allows for the quick and leak-free connection of a hose.
100% USP / EP / JP Compliant
Like all ERWEKA products, the DT 950 / DT 9510 series is 100% USP / EP / JP compliant.
