# Advanced powder analysis by GranuHeap, GranuDrum and GranuPack

## You would like to perform advanced powder analysis using GranuHeap, GranuDrum and GranuPack

### Optimize your powder processes with GranuHeap, GranuDrum and GranuPack

Mastering powders and their flow ([rheology](https://filab.fr/en/our-services/our-expertise-services/rheological-analysis-laboratory-polymer-rheology/rheological-analysis-of-powders-in-the-laboratory.md)) is a strategic issue in many sectors. sectors: [pharmaceuticals](https://filab.fr/en/sectors-of-activity/analysis-industry-pharmaceuticals.md), [cosmetics](https://filab.fr/en/sectors-of-activity/laboratory-analysis-cosmetics.md), [medical devices](https://filab.fr/en/sectors-of-activity/laboratory-analysis-medical-devices.md), [energy](https://filab.fr/en/sectors-of-activity/laboratory-analysis-nuclear-energy.md), [metallurgy](https://filab.fr/en/sectors-of-activity/laboratory-metallurgy-steelmaking-analysis.md), [additive manufacturing](https://filab.fr/en/our-services/our-analysis-services/laboratory-analysis-powder-characterization/additive-manufacturing-powders/), [defense](https://filab.fr/en/sectors-of-activity/laboratory-analyses-tests-defense-security-sector.md), and more.

Poor flow, unstable compaction, or batch-to-batch variability can directly impact product quality, productivity, and regulatory compliance.

At the FILAB laboratory, we perform [advanced powder analysis](https://filab.fr/en/our-services/our-analysis-services/laboratory-analysis-powder-characterization.md) using **GranuHeap, GranuDrum, and GranuPack** instruments.
The goal is **to precisely characterize powder behavior to secure your processes and accelerate your development**.

## Our advanced powder analysis techniques

### GranuHeap: precise measurement of static fluidity

The **GranuHeap** allows for automatic and highly reproducible measurement of the angle of repose.

What we analyze:

- Angle of repose
- Pile evolution
- Flowability indicators

Industrial applications:

- [Raw material validation](https://filab.fr/en/our-services/our-analysis-services/laboratory-raw-material-inspection.md)
- Supplier comparison
- Bat-to-batch quality control
- [Formulation selection support](https://filab.fr/en/our-services/our-expertise-services/laboratory-deformulation-analysis-reverse-engineering.md)

### GranuDrum: dynamic behavior and cohesion of powders

The [GranuDrum](https://filab.fr/en/our-services/our-expertise-services/rheological-analysis-laboratory-polymer-rheology/powder-rheology-granudrum.md) analyzes powder under controlled rotation to determine:

- Dynamic cohesion
- Dynamic angle
- Flow rate index
- Sensitivity to operating conditions

Benefits:

Ideal for simulating conditions similar to industrial processes (mixing, conveying, additive manufacturing).

Sectors concerned:

- Pharmaceuticals (compression, filling)
- Metal additive manufacturing
- Cosmetics (loose powders, pigments)
- Technical materials

### GranuPack: density and compaction capacity

The **GranuPack** measures:

- [Bulk density](https://filab.fr/en/our-services/our-expertise-services/density-analysis-density-measurement-in-laboratory/laboratory-analysis-of-bulk-density.md)
- [Tap density](https://filab.fr/en/our-services/our-analysis-services/laboratory-analysis-powder-characterization/tap-density-measurement-laboratory.md)
- Compressibility index (Hausner, Carr)
- Settling kinetics

This data is essential for:

- Container sizing
- Transport optimization
- Tablet compression
- Powder stability during storage

### Why characterize the behavior of powders?

The properties of a powder are not limited to its granulometry. Two powders with the same particle size distribution can exhibit completely different behaviors in production.

Critical parameters to control:

Fluidity and resting angle

Flow dynamics

Sensitivity to humidity or vibrations

Interparticle cohesion

Apparent density and packed density

These characteristics directly influence:

Filling molds or capsules

The homogeneity of the mixtures

Repeatability in additive manufacturing

Compression or sintering processes

The stability of batches in storage

### The benefits for manufacturers of advanced powder analysis

##

Reduction of production downtime

Improved repeatability

Securing product performance

Supplier decision support

Acceleration of development phases

## Instruments for the analysis of powders :

- **[GranuFlow](https://www.granutools.com/en/instruments):** measurement of flow through orifices, a key indicator of powder flowability.
- **GranuCharge:** measurement of the electrostatic properties of metal powders.

### Our additional services

GranuDrum measurement is part of a comprehensive material characterization strategy. The results can be correlated with:

[Chemical composition analysis](https://filab.fr/en/our-services/our-analysis-services/chemical-analysis-laboratory.md) of metallic powders using [ICP-AES, ICP-MS](https://filab.fr/en/our-technical-resources/laboratory-analysis-icp-icp-ms-icp-aes.md) and/or using C/S, O/N, and H elemental analyzers

[BET specific surface area measurements](https://filab.fr/en/our-technical-resources/laboratory-analysis-bet.md)

[Density measurements](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-nanomaterial/helium-pycnometry-analysis-laboratory/) in accordance with the ASTM B527 and ISO 3953 standards

[Granulometric analysis](https://filab.fr/en/our-services/our-analysis-services/laboratory-granulometric-analysis.md) using [laser granulometry](https://filab.fr/en/our-technical-resources/laboratory-analysis-laser-granulometry.md) in accordance with the ISO 13320 standard

[Flowability testing](https://filab.fr/en/our-services/our-analysis-services/laboratory-analysis-powder-characterization/laboratory-flowability-testing.md) in accordance with the ASTM B213, ISO 4490 and ASTM B964 standards

[SEM FEG EDX](https://filab.fr/en/our-technical-resources/laboratory-analysis-sem-scanning-electron-microscopy.md) or [Optical Microscope](https://filab.fr/en/our-technical-resources/laboratory-of-analysis-and-observation-by-optical-microscope-mo.md) morphological analysis

This comprehensive approach helps to identify the root causes of a flow or spreading problem, and to guide corrective actions tailored to your process.

## Our FAQ

 How to get a quote from FILAB?
To obtain a quote, you can contact our team via our contact form, by phone, or by email.

Simply tell us your requirements (type of material, desired analysis, applicable standards, urgency, quantity of samples, etc.). We will then send you a personalized technical and pricing proposal within 24-48 hours.

 What is the typical duration of the analysis?
Turnaround times vary depending on the nature of the analysis and the complexity of the expert assessment project.

However, FILAB is committed to providing fast turnaround times tailored to your industrial constraints and urgent needs.

 What is the difference between GranuHeap, GranuDrum and GranuPack?
The three instruments are complementary:

- **GranuHeap**: measures static fluidity via the angle of repose.
- **GranuDrum**: characterizes cohesion and dynamic rotational behavior.
- **GranuPack**: analyzes bulk density, packed density, and compressibility.

By combining these three approaches, it is possible to obtain a comprehensive view of a powder's behavior.

 In what situations should GranuHeap be used?
The GranuHeap is particularly well-suited for:

- Routine quality control
- Supplier comparison
- Rapid flowability assessment
- Raw material qualification

It is ideal for detecting behavioral drift between batches.

 Can these results be correlated with production performance?
Yes. Expert data interpretation allows us to link the measured parameters to:

- Line flow difficulties
- Compaction defects
- Mass variations
- Homogeneity problems

At the Filab laboratory, analysis goes beyond measurement: it is contextualized within your process.
