High-Shear Laboratory Mixers
The latest development in high-shear lab mixing – the Silverson L5M-A – is ideal for all laboratory work, research and development, QA analysis and small-scale production in all industries.
The L5M-A Laboratory Mixer is suitable for the widest range of applications – mixing, emulsifying, homogenizing, disintegrating and dissolving – with an efficiency and flexibility unmatched by other machines.

How It Works
The advantages of Silverson’s high shear rotor/stator laboratory mixer over simple conventional stirrers or agitators stem from the multistage mixing/shearing action as materials are drawn through the specially designed Silverson workhead – the heart of every machine.
Stage One
The high-speed rotation of the rotor blades within the precision-machined mixing workhead exerts a powerful suction, drawing liquid and solid materials upwards from the bottom of the vessel and into the center of the workhead.
Stage Two
Centrifugal force then drives materials towards the periphery of the workhead where they are subjected to a milling action in the precision-machined clearance between the ends of the rotor blades and the inner wall of the stator.
Stage Three
This is followed by intense hydraulic shear as the materials are forced, at high velocity, out through the perforations in the stator and circulated into the main body of the mix.
Stage Four
The materials expelled from the head are projected radially at high speed towards the sides of the mixing vessel. At the same time, fresh material is continually drawn into the workhead maintaining the mixing cycle. The effect of the horizontal (radial) expulsion and suction into the head is to set up a circulation pattern that minimizes aeration caused by the disturbance of the liquid’s surface.
