Silverson laboratory mixers: Versatile, fast and built to last

Sep 26 2024

Silverson Laboratory mixers have been sold all over the world to everyone from small start-up companies to larger international brands. They’re built to last – the oldest Silverson Laboratory mixer known to still be in use has been in service for over 70 years!

The popularity of these multi-purpose Laboratory mixers can be attributed to their versatility; they can be used to mix, emulsify, homogenise, disintegrate and dissolve, with an efficiency and flexibility unmatched by other machines.

The advantage of Silverson Laboratory mixers over simple agitators and stirrers stems from the specially designed high shear rotor/stator workhead. Unlike conventional mixers or agitators, high shear mixers utilise specialised rotor/stator technology to generate extremely high shear rates. This creates a powerful suction effect that continuously draws materials into the high shear zone, where they are intensively mixed, before being projected back into the body of the mix at high velocity.

Leveraging this advanced technology, high shear mixers provide remarkable mixing efficiency, enabling:

Faster processing times and increased production throughput.

Finer and more uniform droplet/particle size distributions.

Improved product quality, consistency, and stability across batches.

A range of over 40 workheads, screens and assemblies makes these Laboratory mixers even more versatile. These easily interchangeable workheads enable any machine to perform a wide range of mixing operations and allow one mixer to perform duties that in the past may have required several different pieces of processing equipment.

As well as the workheads supplied as standard with the mixer, this range includes an In-Line assembly for the L5 Series. This assembly converts the L5 mixer to an In-Line mixer/homogeniser with a throughput of approximately 20 litres/minute. The Duplex mixing assembly converts the L5 series into a small-scale version of the production scale Duplex machine, ideal for disintegration and solubilisation of solids, high viscosity mixes, or the incorporation of powders with a tendency to float.

Other assemblies include Tubular units for narrow-necked containers, Sealed Units for sterile materials and an Ultramix powder/liquid mixing assembly.

Part of the key to our success – and that of our clients – is the accuracy with which we can predict the performance of our production scale mixers based on laboratory trials. There’s no point using a laboratory mixer capable of speeds of 25,000 rpm or more if the results cannot be replicated in production. That’s why our laboratory mixers are designed and built to the same tolerances as our production units; comparable rotor tip speed and shear rates across our entire product line means scalable results, every time.
