Flow Controllers

Reliable APSD and delivered dose results depend on accurate and stable flow conditions. The TPK Series provides the control needed to set and monitor critical flow and pressure drops during NGI-based testing for pMDIs and DPIs.

Control and Monitoring

• Critical flow management: Help achieve and maintain sonic flow conditions for pMDI testing.
• Pressure drop targeting: Set ΔP across device components for DPI methods.
• Clear visualization: Read flow and pressure at a glance with simple, reliable displays.
• Repeatable execution: Standardize setup steps to reduce variability between runs and operators.

Workflow Benefits

• Faster setup: Achieve target conditions quickly with intuitive controls.
• Method consistency: Replicate conditions across shifts and sites to support comparable data.
• Integration: Use with NGI and NGI Plus, automated actuation, and sample prep tools to build end-to-end workflows.
• Troubleshooting support: Stable, visible parameters help isolate issues and speed investigations.

Standards Awareness

The TPK Series supports compendial APSD and DDU methods by providing controlled, repeatable flow conditions as part of an NGI workflow. Proper calibration and routine checks help maintain accuracy and instrument readiness.

By bringing clarity and control to flow management, the TPK Series helps inhaler testing teams generate reliable data efficiently and consistently.
