NEW PRODUCTS Titrator JM Science’s AQUACOUNTER® Volumetric Karl Fischer Titrator (AQV-300) is reliable, easy-to-use and has state-ofthe-art performance features which allows measure of moisture content from low to high concentrations quickly and accurately. The AQV-300 has six built-in calculation modes to accommodate solid, liquid and gas samples. It includes a statistics package with one-touch calculations. Four files with preset conditions can be stored in memory and allows instant recall of data for up to 20 samples. A built-in detector monitors titration status and a direct key access allows entry of titration parameters. This compact unit comes with DVD training movie, plasticized Quick-Start guide for use in the lab, paper and pdf manual. Also included, complete accessories, download software for transferring results to a laptop or PC, RS-232 cable, and AQUACOUNTER® KF Reagent starter kit. Choice of thermal printer or impact printer is available.
Reply Card #4926 Pipette Biohit Inc. has introduced a new eLINE Pipette with a range from 0.1 µl to 5 µl and super pipetting feature. Extremely rapid piston movement allows complete emptying of the tip, making it possible to dispense the very small volumes from the air which is not possible with the regular pipettes. Pipetting small volumes against receiving vessel wall or under the liquid surface to get all liquid out of the tip causes contamination risk, decreased precision, and slow pipetting work. Usually contaminations can be avoided by changing the tip between dispensing, but with the eLINE 0.1 - 5 µl 26 BIOTECHNOLOGY FOCUS JULY/AUGUST 2011
dispensing from the air enables continuous work with the same tip as there’s no need to touch the vessel or liquid. The super pipetting feature makes it possible to get the dispensed volume inside e.g. the microplate well when the problem is the electricity of the microplate causing the drop stick to the surface of the well.
fragile protein samples. The instrument also features a temperature control capability, making it suitable for performing automated temperature studies.

workstation automates protein sample preparation, allowing users to start with serum and have peptides ready for LC-MS analysis in as little as ten minutes. In addition to a dramatic reduction in sample prep time, the system generates CV values of less than ten per cent for the overall process of affinity selection, proteolysis, and peptide assay. This automated process removes much of the equipment and manual labor associated with more common sample preparation techniques of proteins for LCMS analysis, freeing the scientist up to dedicate more time to more intellectually challenging activities.
Reply Card #4928 Mobility Instrument Wyatt Technology Corporation Möbius™ electrophoretic mobility instrument can measure precise protein charges. With innovative optical design, Möbius boosts the sensitivity of mobility measurements, enabling protein net charge characterization at much lower concentrations than previously possible. The key to the successful measurement of a proteins’ mobility lies in a much shortened measurement time and the availability of sufficient data to average away molecular diffusion. The Möbius achieves these goals through massive parallelism of its light scattering detection and extends the measurable molecular size range below two nm. A reduced measurement time of fewer than 60 seconds, in most cases, contributes to excellent preservation of precious and
EASY-nLC 1000 The Thermo Scientific EASY-nLC 1000 is the newest addition to the EASY-nLC family of nano-LC products. The EASY-nLC 1000 is unique in its ability to facilitate dedicated separation of biomolecules, such as proteins and peptides, at ultra-high pressures. The instrument can seamlessly integrate with the complete range of Thermo Scientific mass spectrometry (MS) systems for instant, trouble-free operation and uses shorter gradients on 50 µm UHPLC columns with 1.9 µm beads. The EASY-nLC 1000 facilitates peptide and protein identifications by providing higher pressure ratings, along with independent and simultaneous variations of bead size and column length. The device operates on the Thermo Scientific Xcalibur software platform, easily connecting and interfacing with the full suite of Thermo Scientific LC-MS systems. Additionally, the split-free, nano-flow capability of the new system provides excellent retention-time reproducibility (below 0.4 per cent RSD), even for very complex samples. The simple integrated configuration is both easy-to-use and robust.
