Silverson High Shear Laboratory mixing equipment
Silverson Laboratory mixers have been sold all over the world, from small start-up companies up to larger international brands.
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.
Silverson Laboratory mixers are used for a variety of mixing processes from simple liquid/liquid blending, forming emulsions and reducing particle size to more complex mixing applications in emerging industries such as electrically charged film for window tinting and exfoliation of graphite for isolation of graphene. They are ideal for all routine laboratory work, research and development, QA analysis and small scale production.
Silverson offers a comprehensive range of Laboratory scale mixers which are used across industries as diverse as food, cosmetics, pharmaceuticals and chemicals. Whether you are processing 1ml or mixing batches of 50 litres, whatever your application, you’ll be sure to find a mixer to suit your needs.
Silverson L5M-A Laboratory mixer
The ‘standard’ L5M-A model is the latest development in high shear laboratory mixing. 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 projected back into the body of the mix at high velocity. With this method, ingredients are fully incorporated and any agglomerates are eliminated.
The L5M-A model will soon be 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.
There are over 40 workheads, screens and assemblies available for Silverson Laboratory mixers. 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.
Silverson Sealed Unit Laboratory mixer
For mixing in clean-rooms and applications in the biotechnology and pharmaceutical industries, the Silverson Sealed Unit Laboratory Mixer is ideal. It has been designed so that processing can be carried out under conditions of absolute safety, since the mechanical seal protects sterile materials from airborne contamination and eliminates the risk of materials escaping into the surrounding atmosphere.
The efficiency of the machine is such that materials are reduced to a fine homogeneous suspension in a few seconds, with virtually no heat rise. In the latest product video from Silverson, see how the mixer’s special Quick-Release mechanism works. This mechanism permits any of the Sealed Unit Mixing Assemblies to be easily attached or removed. Once attached, the mechanism hermetically seals the mixing assembly and vessel, preventing any contamination.
In-Line mixing at Laboratory scale
For applications where an In-Line mixer is required, Silverson offers an In-Line mixing assembly for the L5 Series, converting the L5 mixer to an In-Line mixer/homogeniser with a throughput of approximately 20 litres/minute.
Where higher throughput or a designated In-Line laboratory unit is required, Silverson have designed 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.
Scale up to pilot and full scale production
Some mixer manufacturers specialise in production scale models but have no laboratory scale mixers; conversely some offer high speed laboratory mixers that have no production equivalent. This can make it difficult if not impossible to scale up successfully from the lab to full production. 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.
Silverson offers the largest range of capacities from a single manufacturer - from 1ml laboratory units up to some of the largest disintegrator systems on the market - and because all Silverson mixers are manufactured to the same precision engineered tolerances anything you produce in the laboratory can be replicated in production and scalable results are achievable across the entire product range, without the need for reformulating.
