Silverson laboratory mixer with versatile mixing assemblies

01 Oct, 2025

The L5 Series Laboratory Mixer is suitable for the widest range of applications – mixing, emulsifying, homogenising, disintegrating and dissolving – with an efficiency and flexibility unmatched by other machines. This is achieved through the use of over 40 interchangeable workheads and screens available for the Silverson L5 series, which increases versatility and the number of applications processable in the laboratory.

The L5M-A multipurpose laboratory mixer is supplied with a number of interchangeable workheads as standard, including a General Purpose Disintegrating Head, Square Hole High Shear Screen, Standard Emulsor Screen and Axial Flow Head. Each of these workheads are beneficial in different applications, across different industries. These workheads can be quickly and easily changed. Also available are Slotted Disintegrating Heads, Fine Emulsor Screens and Pump Heads, further increasing versatility in the lab. 

For mixing in narrow-necked containers, Silverson offers a range of interchangeable Tubular Mixing Assemblies. These have a capacity of 1ml – 500ml depending on the product viscosity and are compatible with the L5 Series of laboratory mixers.

Other assemblies which can also be used with the L5 Series  include the Duplex, Ultramix and In-Line Mixing Assemblies:

The Duplex assembly comprises two workheads facing in opposite directions. The upper head pulls materials down from the surface of the mix, and provides a coarse disintegrating action, while the lower head draws material up from the base of the mixing container, further reducing particle size to accelerate solubilisation or suspension. This combined use of two workheads makes the Duplex ideal for high viscosity mixes and applications where light or buoyant material (powders, rubbers and polymers, etc.) need to be drawn down from the surface of a mix and rapidly dispersed.

The Ultramix assembly is designed for applications that are beyond the capabilities of a conventional agitator or stirrer but do not necessarily require the intense high shear of a Silverson rotor/stator mixer.

The In-Line assembly fits onto the model L5 Series Laboratory range and converts it into an In-Line mixer/homogeniser. The centrifugal action of the rotor in the high shear rotor/stator workhead generates a non-positive pumping action which gives a throughput on low viscosity liquids of approximately 20 litres/minute, reducing as the viscosity increases. The In-Line assembly is suitable for use at atmospheric pressure only. 

For further details about the L5 series and other models in the Silverson Laboratory range, including the Verso - a benchtop In-Line mixer and the FMX5 - a laboratory powder/liquid mixer, please visit the Silverson website or contact Silverson to arrange a laboratory trial at your facility.
