Fumed Silica, well known by its trade names Aerosil® and Cab-o-sil®, is very difficult to disperse for a number of reasons. The powder is extremely low density so tends to float on the surface of the liquid base.
Conventional mixers and stirrers aren’t capable of rapidly incorporating the powder and activating its thickening effect so formulations often contain excessive amounts of Fumed Silica to compensate for this.
Due to the fineness of the powder, dusting can also cause problems. The high shear action of a Silverson Machines, Inc. mixer can solve these problems while also improving your product quality, stability and mixing times.
Silverson Laboratory Mixers Are At The Forefront Of Graphene Research
A leading university recently placed an order for (13) Silverson Laboratory mixers for their new graphene center. The new facility will help accelerate graphene commercialization. Graphene is a two-dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb structure one million times thinner than a sheet of paper. It is the strongest known material – 200 times stronger than steel, it is highly conductive of both heat and electricity, and yet lightweight and flexible, making it a desirable material for use in many industries including aerospace, engineering, digital electronics, bio-medicines, transport and energy.
Graphene was first isolated from graphite in 2004 using a sticky tape method – removing flakes from a piece of graphite using a piece of sticky tape. By repeatedly separating the graphite fragments, flakes just one atom thick were created. Although this method is still used in laboratories it cannot be replicated on a larger scale, and research into ways of isolating graphene in sufficient amounts to be commercially viable has been ongoing for some years. A process called exfoliation, which is the high shear mixing of graphite in a suitable solvent, has been proven to isolate small but significant amounts of graphene.
Silverson mixers have the high shear necessary to reduce the graphite down to usable defect-free graphene, and the equipment has been used by many of the leading researchers due to the ease of scale up from the laboratory mixers to larger production models. Subsequently Silverson have already sold mixers to research establishments all over the world for this application. The Model L5M-A Sealed Unit, L5M-A standard unit, and the Model AX5, each with a full range of work-heads, is useful equipment for this research work.
Integrated Process Engineers & Constructions, Inc., also known as IPEC, has been providing a wide range of custom modular process systems and components for the pharmaceutical, biotech, food, dairy, chemical, and biofuel industries since 1996. IPEC designs and fabricates complex systems from start to finish.
CESCO was involved in a Media & Buffer Prep System project with IPEC for a large pharmaceutical company. Above are pictures of the final system during the Factory Acceptance Test.

By utilizing flow meters, positive displacement pumps, control values, static mixers and other process sensors, IPEC is able to design and construct blending systems to incorporate ingredients into a continuous product stream. Ingredients can be supplied from totes or skid-mounted vessels while instrumentation and mechanical components work together to blend ingredients dynamically and accurately to user-defined ratios and production rates. Integrated CIP capabilities, product recovery (pigging) systems, and alternating ingredient vessels (for continuous production) are available.
IPEC recently delivered Ultrafiltration/Diafiltration (UF/DF) and Virus Filtration systems to a pharmaceutical client. The customer came to IPEC with desired production rates and preferred 3rd party filtration technologies, and asked that IPEC assist with process development.

DEC Group has solutions for:
The PTS Powder Transfer System is a contained transfer system with a wide range of applications in addition to reactor charging. With the use of vacuum and pressure, the PTS can effectively move powders as if they were liquid. This reliable transfer system is capable of dispensing both dry and wet powders and granules.
DEC Group’s PTS-Feeder offers a single step solution to emptying process equipment and filling bags, drums, and big bags with accuracy. The discharge of the Feeder is effected by vibration and accurate dosing is guaranteed by an adjustable piston valve at the outlet. This device discharges most equipment into a wide range of different types of packaging, proving particularly effective when space above or below the equipment is limited. The PTS-Feeder is highly flexible and mobile, which allows for simple integration into existing processes. With the use of the one step PTS-Feeder, there is not a need for conventional feed hoppers and intermediate silos.
TheBatchmixerprovides ultimate speed and flexibility while reducing overall process times compared to traditional systems. Operators of the Batchmixer are able to mix powders with different characteristics in a contained environment. This system is beneficial for pharmaceutical applications where active substances must be handled without contamination or changes to physical properties.

Cleaning a Platular® Heat Exchanger
The Platular® heat exchanger was designed for easy maintenance and a reduction in maintenance costs.
The corrugated plates in this model increases turbulence with local vibrations of the fluid’s speed. These plates permit chemically cleaning without having to open the unit.
For simple maintenance, the Platular® was designed with a lack of of gaskets at the exchange surface level. The only gaskets are flat gaskets on the door and do not need to be changed at each opening.
The units are equipped with hinged doors which allows for the Platular® to be opened rapidly in order to perform mechanical cleaning with high-pressure cleaners. This process is typically performed during plant shutdowns.
