A New Standard in Dry Powder Dispersion

Vision Analytical has once again pushed the boundaries of particle characterization technology. Our latest innovation — the Recirculating Dry Suspension Module — is the first of its kind in the world.

This new module, designed for the Raptor Particle Size and Shape Analyzer, delivers a breakthrough solution for laboratories analyzing dry powders that are fragile, limited in quantity, or sensitive to air exposure.

The Problem with Traditional Dry Dispersion Systems

Until now, most dry powder suspension system on the market has been single-pass and pressure-based. These systems rely on strong air pressure to move samples through the analyzer.

While effective in keeping samples flowing, they introduce several serious limitations:

  • ⚠️ Particle Breakage: High air pressure can damage fragile or irregularly shaped particles.

  • ⚠️ Poor Representativity: Since the sample passes only once, the analysis may not represent the true population of particles.

  • ⚠️ Sample Waste: When sample quantity is limited, single-pass systems make repeat measurements difficult or impossible.

These limitations make it challenging for users who need precise, repeatable results — especially when working with valuable or delicate materials.

The Vision Analytical Solution: Recirculation and Control

Our Recirculating Dry Suspension Module eliminates these issues with a gentle, closed-loop design. Instead of forcing a single pass under pressure, the system recirculates the sample continuously, ensuring every particle has an equal chance of being imaged and analyzed. (Patent Pending)

Key Advantages:

✅ Recirculating Flow Path – Allows representative sampling and repeatable results.
✅ Low-Pressure Dispersion – Protects fragile or sensitive particles from damage.
✅ Ideal for Small Samples – Maximizes use of limited material.
✅ Optional Closed System – Enables analysis in controlled or isolated environments.

This revolutionary design enables true dynamic image analysis (DIA) of dry powders without compromise for Particle Size, Particle Shape, and Particle Concentration.
