In many laboratories, particle size analysis faces a major constraint: the limited amount of sample available. Whether the materials are expensive, rare, or difficult to prepare, every milligram counts. Our MiniFlow accessory was developed precisely to address this need. It is designed for laser diffraction particle size measurement and is compatible with our LA-960 particle analyzer.
Thanks to its optimized design and full automation, the MiniFlow significantly reduces the sample volumes required without compromising analytical performance.
A system designed for small spaces, without compromise
The MiniFlow is a low-volume circulation system that offers all the advantages of a standard system while drastically reducing the amount of dispersant and sample required.
With a dispersant volume ranging from 35 to 55 mL and a sample quantity as low as 0.2 mg, it becomes possible to analyze precious materials or those available in very small quantities.
Contrary to popular belief, working with small volumes does not mean compromising on the quality of results. In fact, our MiniFlow accessory maintains a wide measurement range (0.01 to 1000 µm) as well as excellent reproducibility and a fast analysis time of approximately 60 seconds.
This allows us to maintain performance equivalent to a conventional system, while using significantly less material.
Full automation for greater simplicity
One of the MiniFlow’s key advantages is its software integration. The system operates exactly like a standard flow cell:
- Automatic filling
- Automatic rinsing
- Automatic draining
- Full control via software (compatible with Method Expert)
As a result, no manual intervention is required. The user benefits from a seamless, reproducible, and secure experience.
Another practical advantage of this automation is that switching from the standard system to the MiniFlow takes just a few seconds, without any tools. This makes it easy to adapt the instrument to the analytical needs of the moment.
An ideal solution for sensitive or valuable samples
The MiniFlow is particularly valuable in situations where the sample is limited or critical. Typical applications include rare or expensive materials, R&D projects with limited quantities available, pharmaceuticals or cosmetics, pigments, polymers and resins in oil-based dispersions, and samples requiring organic solvents.
In fact, the system is compatible with all types of organic solvents, offering great flexibility in dispersion protocols.
Reducing environmental risks and costs
In addition to reducing sample volume, the MiniFlow also contributes to a more environmentally responsible approach in the laboratory. By using less solvent, purchasing costs are reduced. Furthermore, this results in less waste and, consequently, lower disposal costs. Finally, fewer operators are exposed to hazards during handling, which improves safety. It is therefore a relevant solution for laboratories seeking to combine analytical performance with an environmental approach.
Optimized dispersion, even for complex samples
The MiniFlow features an ultrasonic probe (40 kHz) with multiple power settings, enabling the effective dispersion of agglomerated particles.
This ultrasonic probe is paired with an adjustable centrifugal pump offering 15 speed settings and an optimized circulation system.
This configuration ensures uniform dispersion, which is essential for obtaining reliable results in laser particle size analysis.
Quick and easy maintenance
Despite its sophistication, the MiniFlow remains very easy to maintain. The measuring cell can be easily removed for cleaning, which minimizes downtime and simplifies maintenance procedures.
The materials used (Tempax glass, SUS316 stainless steel, Teflon, titanium alloys) ensure excellent chemical resistance and increased durability, even with harsh solvents.
The MiniFlow represents a major advancement for laboratories facing sample volume constraints. It combines:
- Low sample and solvent consumption
- Full automation
- High analytical performance
- Flexibility of use
Whether for research, quality control, or development applications, it stands out as an essential solution for optimizing your particle size analysis while reducing costs and your environmental impact.
