Paraffin emulsion experiments keep going wrong?
Uneven emulsification and particle size exceeding target are common pain points for many formulation teams.

Watch our test with Weiss high-pressure homogenizer:
🎯 Requirement: D90 ＜8 μm
🔧 Process: 60℃ constant temperature | 1300 bar | 3 passes
📊 Result:
Before homogenization: D90 = 37 μm, poor dispersion
After homogenization: D90 = 6.7 μm (81.9% reduction)
Fine milky white emulsion, no agglomeration or phase separation, improved storage stability.

Our homogenizer comes with precise temperature control, customized for paraffin & wax emulsion preparation. Stable operation and easy to use for lab R&D and pilot scale-up.

Troubled by rice husk silica production issues such as oversized particle size, severe agglomeration and slurry stratification?
Our Weiss high-pressure homogenizer solves these challenges with triple effects of ultra-high pressure shearing, impact and cavitation. It breaks coarse rice husk silica particles, disperses agglomerates and prevents re-agglomeration while preserving the original pore structure and activity of rice husk silica. Stable slurry with consistent batch quality for mass production.

Experiment Process:
1. Weigh rice husk silica raw material and prepare the initial slurry.
2. Pre-disperse by high-speed shear mixer.
3. Feed slurry into high pressure homogenizer: 1 pass at 800 bar, then 10 cycles at 1300 bar.

Test Result:
Original D50: 100 μm
After homogenization: D50 = 2.6 μm, particle size reduction up to 97.4%.
The treated slurry stays stable without sedimentation, stratification or re-agglomeration after long-term standing. The intrinsic structure and activity of rice husk silica are well maintained for downstream applications.

Struggling with nickel powder that won't refine? Wide particle size distribution, hard agglomeration, unstable mass production, and severe layering? The Weiss High-Pressure Homogenizer solves it all in one pass.

**What it does**
Driven by the triple synergistic forces of shear, impact, and cavitation, it:
• Precisely controls nickel powder particle size distribution under ultra-high pressure
• Breaks up hard agglomerates at the root, preventing re-agglomeration
• Fully preserves the spherical morphology and crystal lattice structure

The result: high-quality nano nickel powder with excellent dispersion, strong electrical conductivity, and high catalytic activity.

**The experiment**
Our lab was required to achieve a nickel powder D90 below 2 μm, but the suspension we received showed severe layering. Here's the full process:
1️⃣ Pre-treatment with a high-speed shear mixer
2️⃣ Transfer to the high-pressure homogenizer at 1400 bar
3️⃣ Homogenize for 8 cycles
4️⃣ Sample and measure with a laser particle size analyzer

**The results**
• Before: initial D90 = 120 μm
• After: D90 = 1.99 μm — a 98.34% reduction
• No layering even after long-term standing

The nickel powder now fully meets our teacher's requirements. If you're dealing with particle size control, agglomeration, or dispersion issues in powders, this is the machine for you.

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.
