Silverson Machines at CHEMUK 2024

This year, Silverson Machines will be exhibiting at CHEMUK on Stand J56. Here is an overview of the products that will be available to visitors to view on the stand.

Laboratory Mixers

Silverson Laboratory mixers have been sold all over the world, from small start-up companies up to larger international brands. The popularity of Silverson 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.

On the CHEMUK stand, visitors will be able to see the ‘standard’ L5M-A model. The L5M-A model is now available with the body finished in white engineered polymer for increased durability and ease of maintenance. The updated radiused edges allow for easier cleaning. With its integral tachometer, ammeter and programmable timer, the L5M-A offers a level of instrumentation invaluable in applications where process validation and repeatability are required.

The advantage of a Silverson over simple agitators and stirrers stems from the specially designed rotor/stator workhead; the high speed rotation of the rotor blades draws materials into the workhead where they are intensively mixed, before being subjected to intense mechanical and hydraulic shear as they are projected back into the body of the mix at high velocity. With this method, ingredients are fully incorporated and any agglomerates are eliminated.

Benchtop In-Line mixer/homogenisers

Where a designated In-Line laboratory unit is required, Silverson have designed the Verso. Visitors to the stand at CHEMUK will be able to see the Verso, a bench top In-Line mixer which can be supplied with a vessel package to replicate a recirculation process at pilot scale. The Verso offers an easy and accurate means of forecasting the performance of larger In-Line mixers under full-scale working conditions.

The Verso is now also available in an Ultra Hygienic specification as the Verso-UHS, and for High Viscosity Mixing as the Verso-UHS-HV. A conversion kit is available allowing the Verso-UHS-HV to be configured as an FMX5 laboratory-scale Powder/Liquid mixer, further increasing the mixer’s versatility.

New Small-Scale In-Line Mixers

Silverson Machines is launching new mixer variants at this year's CHEMUK show. The new mixers have been developed in response to demand for small-scale In-Line mixers and powder/liquid mixers that bridge the gap between the laboratory scale mixers detailed above and production scale mixers currently available in the Silverson product range.

One of these new mixers is the 150 UHS In-Line, which has been specifically designed for Ultra Hygienic applications typically encountered in the pharmaceutical and biotech industries, where the smallest production scale mixers may be too large, but laboratory equipment doesn’t offer sufficient capacity. These mixers are built to the same high specification as production scale UHS mixers and can be supplied with Silverson-designed hygienic single mechanical shaft seals, which can be converted to hygienic double mechanical shaft seals suitable for pressurised flush. They have a crevice-free construction and are designed for Clean-In-Place (CIP) and Sterilise-In-Place (SIP) operation. Ideal for batches of up to 50 litres they can also be supplied with multi-stage rotor/stator workheads, offering intense yet targeted high shear capability.

In-tank Batch Mixers

One of the main advantages when choosing a Silverson Laboratory mixer for R&D or pilot scale production is the ability to scale up from the laboratory to full scale production models with ease.

For in-tank mixing of volumes up to 30,000 litres, Silverson supplies a comprehensive range of Batch mixer models. Capable of performing all of the same mixing process as Silverson Laboratory mixers, it is possible to reduce mixing times by up to 90% when using high shear Batch mixers as opposed to traditional mixing methods such as stirrers or agitators. Small to medium range Batch mixers can be used on mobile floor stands, further increasing their versatility.

New Small-scale Powder/liquid Mixer

Another new mixer launching at CHEMUK is the FMX10. This mixer bridges the gap between the laboratory scale FMX5 and the larger Flashmix product range. It provides a simple, effective and hygienic means of powder/liquid mixing on a small scale, with a batch size of up to 50 litres, depending on viscosity. Featuring the same pumping rotor design as the HV model, the FMX10 is able to process higher viscosity mixes, and the option of a high speed motor, capable of 9,000rpm, and Flameproof specification makes this model even more versatile.

For mixing large quantities of powder, Silverson developed the Flashmix powder/liquid mixer, which will also be on the stand at CHEMUK.

These are just a few of the mixer options available in the Silverson product range, you can find out more about additional models on the Silverson website.
