Gentle Rocker

Consistent sample extraction underpins reliable APSD and delivered dose results. The Gentle Rocker supports these steps with low-shear, uniform mixing that helps improve recovery while limiting foaming and re-aerosolization.

Key Capabilities

• Adjustable speed and tilt: Tune motion to match solvent properties and target recovery profiles.
• Broad compatibility: Use for NGI stage extraction, throat and pre-separator rinses, and DUSA solutions.
• Compact and quiet: Conserve bench space and maintain a comfortable work environment.
• Easy to use: Simple setup and controls support quick training and daily consistency.

Workflow Benefits

• Repeatable extraction: Controlled motion helps reduce operator variability.
• Higher throughput: Process multiple samples in parallel with predictable timing.
• Robust methods: Standardized settings simplify method transfer and documentation.
• Better ergonomics: Reduce manual swirling and repetitive handling.

Typical Applications

• NGI and NGI Plus stage extractions
• Dose collection solution mixing for pMDIs, DPIs, and sprays
• Pre- and post-wash steps during cleaning validation
• Formulation screening requiring gentle mixing

Integration With Inhaler Testing

The Gentle Rocker complements DUSA shakers, automated actuation, and sample preparation units. By standardizing extraction motion, it helps laboratories achieve more consistent recoveries and cleaner mass balance checks. When combined with data analysis software and environmental control, it contributes to a streamlined, end-to-end workflow with clearer, more defensible results.
