Vision Analytical has pushed the boundaries of particle characterization technology with its Recirculating Dry Suspension Module.
This recent innovation is the first of its kind in the world: A new module designed for use with the Raptor Particle Size and Shape Analyzer.
The Recirculating Dry Suspension Module represents a pioneering solution for laboratories working with limited-quantity, fragile, or air-sensitive dry powders.
Issues with Traditional Dry Dispersion Systems
The majority of dry powder suspension systems on the market have historically been single-pass and pressure-based. These systems move samples through the analyzer using strong air pressure, and while they are effective in keeping samples flowing, single-pass and pressure-based systems do face several serious limitations:
- Particle breakage, with high air pressure potentially damaging irregularly shaped or fragile particles.
- Poor representativity, with the analysis potentially failing to represent the true population of particles due to the sample passing only once.
- Sample waste, with single-pass systems making repeat measurements difficult or even impossible when the sample quantity is limited.
These limitations pose challenges for users seeking precise, repeatable results, particularly when working with delicate or valuable materials.
The Vision Analytical Solution
The Recirculating Dry Suspension Module addresses these issues using a gentle, closed-loop design.
Rather than forcing a single pass under pressure, Vision Analytical’s patent-pending system continuously recirculates the sample, ensuring that every particle has an equal chance of being imaged and analyzed.
Key advantages of the Recirculating Dry Suspension Module include:
- A recirculating flow path that enables representative sampling and ensures repeatable results.
- Low pressure dispersion, ideally for protecting sensitive or fragile particles from damage.
- Suitability for small samples by maximizing the use of limited material.
- An optional closed system, facilitating analysis in isolated or controlled environments.
This design enables true dynamic image analysis of dry powders without compromise, accurately determining particle size, shape, and concentration.

Conclusion
Vision Analytical continues to be at the forefront of the development of smarter, more flexible particle analysis solutions. The company’s instruments allow users to acquire accurate, repeatable, and representative results, even when working in challenging conditions.
The new Recirculating Dry Suspension Module confidently captures the true shape and size of particles, whether a material is fragile, limited, or sensitive to air.
