Laboratory mixer: testing and mastering very high-viscosity products

Introduction

The development of very high-viscosity products requires equipment capable of faithfully replicating industrial conditions on a small scale.

The RMC Marc Guittard laboratory mixer is designed to:

  • test complex formulations
  • validate mixing processes
  • ensure a smooth transition to industrial scale
  • it is a strategic tool for R&D teams and process engineers working on pasty, sticky or no How the laboratory mixer works

How the Laboratory Mixer operates

A scaled-down version of industrial mixing

The laboratory mixer operates on the same principle as industrial machines:

  • two counter-rotating Z-blades (Sigma)
  • a compact tank suitable for small volumes
  • a drive system designed for high viscosities

 

It enables the precise reproduction of:

  • mechanical stresses
  • the rheological behaviour of the product
  • actual mixing conditions

A faithful simulation of the industrial process

 

Unlike conventional laboratory mixers, the RMC mixer allows work to be carried out on:

  • non-flowable products
  • extremely viscous formulations
  • materials that are difficult to dispersen-flowing products.

 

It thus provides a direct link between the laboratory and production.
