BioLector Pro - micro bioreactor system THE BioLector Pro is the most advanced microbioreactor system on the market. It combines the proven, scalable BioLector technology with an innovative microfluidic chip. The BioLector Pro is designed to perform high-throughput cultivation in batch or fed-batch mode together with online monitoring and controlling of the most common fermentation parameters. Features include: • 32 parallel microbioreactors • Individual pH control • Individual feeding • All bioreactors and feeding solutions on a single plate • Full disposable platform
The system is based on microtiter plate formats and operates with noninvasive, optical sensors. The disposable 48-well microtiter plate of the BioLector Pro microbioreactor features online measurements of biomass, fluorescence, pH and DO. and at the same time controls pH and feeding rates through micro-valves and micro-channels. These unique microfluidic components realise for the firsttime continuous feeding and pH control on a
Biologically active proteins yield meaningful data Bind, wash, elute and concentrate your protein in the new all-in-one Amicon Pro WHEN you start with consistent yields of active, native-folded protein, you’re giving your experiment the best chance to succeed. If your current protein preps involve juggling columns, dialysers and multiple transfer steps, you could be introducing variability into your data. For your next protein preparation, choose the simple, gentle method that tackles even the most labile and poorly expressed proteins - the Amicon Pro purification system. When your proteins behave, your research will flourish. The device combines affinity-based spin column purification with downstream sample concentration and buffer exchange. Featuring a large reservoir that accommodates a range of sample volumes, the device reduces the need for multiple centrifugation steps. Simply attach the included Amicon ultra filter for simultaneous elution, concentration and
highly efficient diafiltration (>99%) in a single spin. Not only does the Amicon Pro purification system represent a gamechanging improvement in general affinity purification, but it also transforms applications such as depletion of abundant proteins, protein enrichment, buffer exchange and clean-up of antibody labelling reactions. Because of the extremely flexible, modular design of the Amicon Pro system, you can configure the perfect centrifugal purification device for your protein preparation.

Zeutec Grain SpectraAlyzer What it does for you THE SpectraAlyzer is a near-infrared spectrometer which is dedicated to analysing the composition of samples using the near-infrared absorbance characteristics of the sample spectra. It is suitable for the compositional analysis of a wide variety of food products like grains, cereals, oil seeds and flour. All possible parameters of grain products such as protein, moisture, oil, ash, hardness and water absorption can be analysed simultaneously.
microtiter plate format. There are no tubings and no liquid handlers needed anymore; everything is part of the gamma radiated ready-to-use plate. By using the microfluidic-chip technology, an extremely exact and slow dosing down to 50nl can be realised. Two reservoir wells per four individually controllable cultivation reactors are available. All together 32 bioreactor wells and 16 reservoir wells are placed on one plate.
Due to the continuous and rigorous shaking during the optical measurements and over the whole experimental time, it is ideally suited for aerobic cultures in high density. The massive acquisition of relevant bioprocess data allows precise and reliable bioprocess development, strain characterisation, media optimisation and clone screening in short time frames.

Intuitive operation and seamless workflow with cellSens software THE Olympus cellSens software platform creates a uniquely personal and intuitive imaging experience based on the operator’s preferred workflow. cellSens provides full control over the display and placement of icons, toolbars and controls to simplify the desktop and enhance productivity. cellSens is easy to use, powerful and flexible. Using a modular design, the software can be tailored to a budget as well as to the intended imaging applications. This enables the software to grow and adapt to meet evolving research needs.
The sample is top-filled directly into the sample cell of the SpectraAlyzer: there is no need for grinding or other sample preparation at all. The sample is fed through the sample chamber via a robust feeding device and automatically discharged. In order to analyse powder samples such as wheat flour, an optional flour module is an available accessory. Each analyser can be fitted with a test weight module (bushel weight, hectoliter weight) to determine the volume-to-weight ratio of the sample. An automatic path-length adjustment enables the user to quickly analyse a multitude of whole grain and oil seed samples. The instrument is controlled with an easy-to-use icon-driven software, using a modern interface glass panel slider called the ‘Central Operation Slider’, and a colour TFT display with 640x480 pixels.
Features include: • Image capture • Viewing and processing • Measurement and analysis • Collaboration and communication • Fully customisable easy-to-use interface WIRSAM SCIENTIFIC JHB: (011) 482 1060 CPT: (021) 386 9020 DBN: (031) 709 0199 PE: (041) 365 2060 VT: (016) 931 1731 wirsamjb@wirsam.com www.wirsam.com
The innovative graphic user interface and its functions has a similar operability to the AppIe iPod. The user interface is made out of glass for easy hygienic cleaning and years of maintenance-free operation. A web server operating on the instrument allows the direct connection to the World Wide Web so results and maintenance can be done directly from Internet browsers. The web front-end allows remote browser-based instrument supervision and no PC application software is necessary.
