The ERWEKA DT 9510 range of dissolution testers are the bigger sibling of the digital DT 950 series.
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 water bath 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 comparison between the two as reliable as possible and 100% USP/EP compliant. What’s more – the DT 9510 has a fully integrated Audit Trail, making the device fully 21 CFR Part 11 compliant as a standalone bath —ensuring traceability, data integrity, and regulatory adherence at every step.
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 dissolution testers have the same features as it‘s smaller sibling, with digital dissolution testing is done with the help of the latest version of the testing assistant – TestAssist and optional automatic tablet drop.

The DT 9510 can be upgraded even after the initial purchase – 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.
Audit Trail and Method Management
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.
