Troubles in nano‑emulsion preparation: oversized particle size, wide distribution, demulsification, loss of active ingredients, unstable mass‑production.

Weiss high‑pressure homogenizer adopts triple‑effect of shear, impact and cavitation to produce stable nano‑emulsions.
✅ Refine emulsion droplets to nano‑scale
✅ Prevent demulsification, no stratification after long‑term storage
✅ Tolerate high‑temperature sterilization
✅ Preserve active ingredients
✅ Consistent batch performance for R&D & mass‑scale production

Experiment Data:
Initial D90: 77 μm
After homogenization: D90 = 665 nm, reduction rate: 99.14%

Experimental procedure:

1. Prepare initial solution, pre‑treat with high‑speed shear mixer
2. Homogenize at 600 bar for 4 min circulation
3. Boost pressure to 800 bar, repeat 3 cycles

Which one to choose for PLGA‑Curcumin microspheres: microfluidizer or conventional high‑pressure homogenizer?

We conducted a side‑by‑side comparison test with identical raw materials under same parameters: 1000 bar, 2 passes.

🎯Goal: Reduce D50 below 10 μm
🔬Pre‑treatment: High‑speed shear at 7000 rpm for 5 min.

• Conventional high‑pressure homogenizer: D50 =15 μm, failed target, poor batch‑to‑batch repeatability.
• Microfluidizer: D50 =5.8 μm, well below target with excellent reproducibility in triplicate tests.

Microfluidizer delivers finer particle size, narrower distribution and superior stability for microsphere fabrication.

From Agglomerates to a Controlled 0.4% SWCNT Slurry

Dispersing single-walled carbon nanotubes takes more than conventional mixing. It requires a controlled and measurable process.

In this application test, WEISS combines an RPA Pipeline High-Shear Disperser with the WH-PILOT High-Pressure Homogenizer to process a 0.4 wt% aqueous SWCNT slurry.

Key process parameters:

CMC:CNT mass ratio: 1.5:1
High-shear pretreatment: 2,950 rpm
Homogenization pressure: 800 bar
Homogenization cycles: 8
Target OD: 0.52–0.70
Target viscosity: 850–1,250 cP

Based on OD and viscosity testing, the process can be adjusted through additional high-shear treatment or continued circulation and homogenization until the target range is achieved.

The result is a more controlled process designed to reduce agglomerates and improve dispersion uniformity and long-term stability.

WEISS delivers more than equipment—we engineer repeatable dispersion processes for demanding advanced-material formulations.

Contact us to discuss your material, solid content and target viscosity.

A must-have device for researchers! All three core hurdles of nickel powder manufacturing solved at once!

My client needed nickel powder D90 < 2 μm, yet their raw suspension had terrible stratification and D90 up to 120 μm.
Process: High-speed shear preprocessing + Weiss high-pressure homogenizer at 1400 bar for 8 cycles.

Test result: D90 hit 1.99 μm (98.34% size reduction)!
✅ No long-term stratification
✅ Hard agglomerates fully broken without re-agglomeration
✅ Complete spherical nickel powder morphology

Powered by integrated shear, impact and cavitation effects, our homogenizer eliminates all bottlenecks in nano nickel powder preparation.
