Supporting Research in the Synthesis of Inorganic Nanoparticles


The Department of Chemistry & Biochemistry at Brigham Young University (BYU) has chosen the NanoSight LM-10 system to support their research into the synthesis of inorganic nanoparticles, principally metal oxides. The BYU research team of Dr Brian Woodfield are working on the development of an elegantly simple process that allows the group to make a nearly unlimited array of well- defined inorganic nanoparticles that have controlled sizes from 1nm to bulk. The particles are highly crystalline with well defined shapes (usually spherical but also rods). The method produces them with chemical and phase purities as high as 99.9999% while the particle size distribution is controlled to approximately ±10%. Dr Woodfield projects with confidence that they can make industrial size quantities with manufacturing costs significantly less than any other current technique.


Principal user is PhD candidate Betsy Olsen. She has been very impressed with the instrument: “The NanoSight is used to measure particle size as one way to quantify the amount of agglomeration in the process and to see if our de-agglomeration/dispersion techniques are working.” Olsen continued: “The system is used along side other techniques such as TEM and DLS. However, the NanoSight is much faster, less expensive and easier to run than TEM. It provides more control compared to DLS and other traditional particle size analysers as it allows you to visualise what you are measuring particle by particle. For example, this means you can follow a polydispersed system more accurately.” NanoSight’s approach, known as Nanoparticle Tracking Analysis (NTA), has been shown to be ideally suited to both research and process control use. The system is an extremely powerful nanoscale research and development tool for looking at a broad range of particle types and concentrations.

The new three-channel vacuum display and controller COMBIVAC CM 51 from Oerlikon Leybold Vacuum GmbH for industrial and research applications, monitors and controls the complete vacuum range from atmospheric pressure (1000 mbar) down to the ultra high vacuum range (10-9 mbar). All channels can be operated simultaneously and absolutely independently.


The vacuum gauge is designed for Pirani and Penning passive (passive, as there are no electronic parts inside the sensor) sensors, which are radiation resistant and bakeable. The COMBIVAC CM 51 operates in harsh and highly corrosive industrial applications. It is also suitable for use in areas with high levels of radiation and systems requiring high temperature bake out where only passive sensors can be operated.

New Incubators Offer Performance and Value


The new INB-203 CO2 incubators from IKS International offer an exceptional price/performance ratio and are ideal for applications in IVF, cell culture, haematology, cell biology and pharmaceutical laboratories. The INB-203 model is a direct-heat incubator with a capacity of 42 litres and a temperature range from ambient +5°C to 60°C. For those needing lower temperatures, the INB-203C has the added facility of peltier cooling down to ambient -5°C. This will be particularly useful for laboratories without adequate air conditioning, providing unprecedented security against loss of temperature-sensitive material. The larger INB-203 XL is a direct-heat incubator with a generous capacity of 179 litres and a temperature range from ambient +5°C to 60°C.


The design of the INB-203 range shows careful attention to detail. The combination of heating from all 6 internal surfaces with fan-assisted circulation means that


temperature and CO2 levels stabilise quickly and that good temperature accuracy (± 0.25°C at 37°C) is achieved. As an option, the inner glass door can be subdivided into 6 sections (8 in the case of the INB-203XL), to minimise the environmental impact on sensitive samples when the door is opened. Temperature and CO2 levels are monitored by reliable PID and infra-red sensors and there is optional battery backup in case of power failure. These incubators are fully compatible with IKS’ market-leading XiltriX®


laboratory monitoring system. The inner chamber has rounded corners to facilitate cleaning and is condensation-free, helping to reduce the risk of contamination. Units can be stacked to conserve valuable laboratory space.

Innovative Minibioreactors Allows Multiple Simultaneous Cell Culture Trials


Telstar is introducing into the market a completely innovative minibioreactor model to perform animal cell culture screening studies on a scale applicable to R&D. Planned for March 2010, this equipment will be launched on the market under the brand name of Telstar Hexascreen.It is the first minibioreactor on the market to enable animal cell culture trials and experiments on a scale of 10 to 15m, with the capacity to handle six cultures at a time, and a workstation accommodating single-use interchangeable plates to guarantee sterility and speed up the start of the bioprocess. These units offer change of medium, monitoring and control facilities, which enable the collection of information on the main culture variables, such as the temperature, dissolved oxygen/oxygen consumption, pH, optical density and measurement of the spectrum in the visible range, while simultaneously monitoring growth (absorbance) and metabolism (indirectly from acidification/ oxygen consumption).


All these features make the Telstar Hexascreen the most innovative equipment for the pharmaceutical and biotechnology industry market because it speeds up the bioprocess and multiples the opportunities for experimentation by being able to develop six simultaneous cultures and it facilitates the start of the bioprocess by the use of replaceable plates which ensure sterility, requiring the user merely to inoculate the cultures before placing the plate in the workstation. This innovation overcomes the complexity of use usually found in bioreactors, which involve laborious preparation, sterilisation and calibration processes before the start of the cultures, often requiring highly qualified personnel. During 2010, Telstar will develop a new stage in the Telstar Hexascreen minibioreactor by incorporating the fed-batch model for growth and increased productivity of the cell culture.
