Digital Dissolution Tester DT 950 Series Benefits

Future-Ready Software Features

Audit Trail, Method Management, and More | The ERWEKA DT 950 is developed to meet the requirements for compliance and data management for modern laboratories. Its integrated Audit Trail records all user and system actions in detail, including user, time stamp, event, reason for changes, and parameter modifications with old and new values, ensuring complete traceability.

Method Management & Approval allows authorized users to create, edit, and approve methods, while User Management provides secure access control with tailored permissions. The Backup & Restore function enables all important data—including methods, user profiles, reports, settings, and audit entries—to be backed up and restored via USB stick, with every event logged for transparency.

DT 950 Series Touch Interface

1-2-Test! | 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.

LAN Network & USB Printing Capabilities

Network Printing Explained | 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.

TestAssist - Dissolution Testing Easier Than Ever

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.

Help, Anytime

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.

Deutsch, English, Español, Francais, ...

The modern architecture of the ERWEKA operating system supports a wide range of languages (including German, English, Spanish, French, Italien), making the DT 950 the most accessible device ERWEKA has ever developed, anywhere in the world.

Direct Access for Customer Service

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.

Qualification Made Easy

Thanks to the new qualification function, qualifying the DT 950 is very easy. Simply call up the qualification menu and follow the instructions.

Digital Dissolution Tester DT 950 Series Unlimited Upgradeability - At Any Time

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?

Not Only on a Large Scale, but Also on a Smaller One Further Improved

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.
