OverviewThe ATS Xtend™ Offline is a semi-automated dissolution sampling system that withdraws, filters and collects samples for offline analysis. It supports simultaneous sampling from 6–8 vessels and collects into glass tubes, capped LC vials or HPLC/UPLC wellplates. The system standardizes sampling position, withdrawal force, volume, timing and filtration to improve repeatability and comparability of dissolution data.
Benefits- Reproducible sampling: consistent withdrawal positions and standardized procedures reduce variability.
- Offline collection: compatible with tube, capped LC vial and wellplate workflows for HPLC/UPLC analysis.
- Flexible methods: schedule multiple timepoints and automatically replace withdrawn volumes.
- Fast sampling: piston pump enables timepoint intervals under 1 minute.
- Modified‑release support: automated filter changes at defined timepoints for DR/MR protocols.
- Fine filtration: supports filtration down to 0.2 μm for offline analysis when used with the CP piston pump.
- Flexible lab workflow: enables offline analysis without dedicating the dissolution tester to an analyzer.
AutomationThe automated workflow performs simultaneous sampling, filtration and transfer to collection racks or vials. A multi-purpose media selector enables one‑touch sample line cleaning and automated volume replacement or controlled media/pH changes. Video monitoring and automatic temperature protocols support documentation and process control.
Highlights- Standardized sampling parameters for improved data quality and comparability.
- Multi-purpose media selector for automated tube flushing and media handling.
- Effective filtration using tip/disc/syringe filters and the CP piston pump capable of pushing through filters down to 0.2 μm and handling foaming media.
- User interface EasyTouch™ for method selection and start; role‑based access for method modification.
- CenterView™ video monitoring to record vessel behavior and document deviations.
