Scalable Lab System

5 processing solutions in one

Results from R&D testing are fully scalable to production size.


Benefits of the Scalable Lab System™ (SLS)

One machine offering five milling and processing solutions.  Using Smart-Detect technology, the heads can be swapped within seconds with no set up required.

Scalable Lab Milling System by Quadro

The SLS gives the reassurance that particle sizes and distributions achieved in the lab can be directly transferred to the production-scale equipment.  The operating parameters are simply transposed from small-scale to full-scale production.

Key size reduction and material processing technologies are possible from one single platform.  Using the interchangeable heads you can achieve labscale conical milling, hammer milling and screening.  Its bench-top size is space-saving as well as cost-effective.



Conical Milling

Wide range of screens and impellers offering tight granulometry.


High Energy Milling

Predictable narrow PSDs ideal for API and fine chemical applications.


Security Screening

Test in-line security screening and deagglomeration.


Hammer Milling

High impact milling capabilities for finer particle size ranges.


Supported Industries

These products are extensively used in the following applications:

OSD Pharma

Effectively conditioning powders for the pre-compression processing stage.


API Pharma
