The Digital Offline System for the DT 950 and 9510 series is the next step in harnessing the power of digital dissolution testing. It extends the advanced technology of the DT 950 and 9510 series with the first step in dissolution automation: fully automated sampling and storage in vials for separate analysis.
With the updated TestAssist, the user can easily configure and start dissolution tests with automatic sampling on our 7-inch touch display. The design principles introduced with the DT 950 have been applied to offline testing, making it faster, easier and more accurate than ever before. The user is guided through the dissolution test with automatic sampling in a few simple steps. This enables 100% USP / EP / JP compliant dissolution testing without distraction or error and ensures consistently compliant parameters.
But it doesn’t stop there – with user management, conformant handling of the complete Digital Offline system is just the touch of a button away. Users can be easily configured with individual rights, making it easy to restrict functions to authorized users only – such as administrators, operators and service technicians.
The Digital Offline System is our most advanced stand-alone resolution system and provides an easy-to-use entry point into resolution automation.
Digital Dissolution Offline System DT 950 & DT 9510 Series Key Features
100% USP / EP / JP Compliant
USP Methods 1, 2, 5 and 6
Full control of connected hardware
Audit Trail – Full 21 CFR Part 11 compliance
Audit Trail, Method Management, and More
The ERWEKA DT 950 / DT 9510 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.
TestAssist for Digital Dissolution Offline Testing
The intelligent TestAssist has been updated for digital offline testing:
- Easy sample timing configuration
- Advanced offline system settings
- Updated test interface for more information and transparency in the test procedure
User Management
The updated user management enables flexible access control for the digital dissolution system:
- Easy-to-use user rights management
- Password complexity guidelines for safe access control
Stand-Alone Control of Connected Hardware
The digital embedded PC technology in the digital dissolution tester DT 950 and DT 9510 take full control of the connected system hardware: The pump, either PVP or IPC, the automated sampling station ASS-9/-18 and the sample collector. An external computer is not required, saving space, energy and maintenance, and thanks to the digital technology, without loosing comfortable features and USP/EP/JP compliance. Of course, the offline system includes all the other software features of the DT 950 platform, including method memory, sampling station with temperature sensors in each vessel, USB update and FTP data export.
