detector The new Metrohm 887 UV/VIS detector is paired with an 881 Ion Chromatograph and Dosino® PCR delivery system for ultra-low determination of hexavalent chromium. In fact, calibration levels down to 12.5 ppt have been achieved. Key features of the 887 UV/VIS detector include a diode array with 512 diodes, and the ability to select up to 8 variable wavelengths from 190 – 900 nm. The system is capable of recording the spectrum any time during the run, and up to 10 absorption maxima of any spectrum may be obtained to optimize the wavelength for a particular application. As is customary with all instruments available through Metrohm, 887 is backed by expert application and service support. Reply Card #4892

transfection Kit EMD Millipore

launches its new NovaCHOice™ Transfection Kit that accelerates protein production from the suspension Chinese hamster ovary (CHO) cell line. This new reagent is the first kit optimized specifically for this popular cell line, which produces active, soluble forms of recombinant proteins used in research, drug discovery, preclinical studies, or patients. Suspension CHO cells are widely used for recombinant protein production because they are easy to scale-up for cell culture and protein purification. However, suspension CHO cell transfection has been challenging because few optimized transfection reagents were available. EMD Millipore’s NovaCHOice transfection kit overcomes this challenge by enabling efficient delivery of DNA into the cells, resulting in high levels of gene expression and superior protein yields. The NovaCHOice transfection kit can also improve the large-scale production of therapeutic recombinant proteins, such as therapeutic monoclonal antibodies, of which kilogram-scale yields are required per batch.

Cyclone Mill The Retsch cyclone mill TWISTER is specially designed for the processing of foods and feeds for subsequent NIR analysis. The optimized form of rotor and grinding chamber generates an air jet which carries the ground sample through the integrated cyclone into the sample bottle. The air jet prevents the material from heating up, thus preserving the moisture content. The provided sieves guarantee an optimum particle size distribution so that it is not necessary to recalibrate the NIR spectrometer. The rotor speed can be adjusted in three steps allowing for perfect adaptation to the sample requirements. Cleaning the mill is quick and easy as the air jet affects a complete discharge of the material from the grinding chamber. Reply Card #4895

Moisture Analyzer Shimadzu Scien-

tific Instruments announces the availability of the MOC63u moisture analyzer with UniBloc sensor technology for reliable laboratory testing. First introduced by Shimadzu for precision balances in 1989, UniBloc ensures stable temperature characteristics, excellent response time and stable corner-load performance during analyses. The MOC63u features a variety of measurement modes, including multiple ending and drying modes, to suit the sample characteristics. The easy-start mode allows for a fast response time during testing, and the simple keypad permits easy operation. The long-life halogen heater prepares samples efficiently for quick and accurate measurement. In addition, this compact analyzer has a built-in USB port, a large pan size and an illuminated easy-to-read display. Windows® Direct capability lets users integrate weighing results with laboratory software without a special application. Reply Card #4896

Freezer SANYO biomedical solutions division introduces its new, larger 25.7-cubic foot Twin Guard Series -86°C Ultralow Temperature Freezer, the MDFU700VXC, featuring dual cool technology. Designed to preserve the most sensitive, high-value biological, the MDF-U700VXC serves as the ideal critical storage appliance in repositories and medical research facilities. The new freezer has more flexibility in storage space, storing up to 576 boxes (2-inch). The larger storage cabinet combines with dual refrigeration systems for maximum protection. Because of the two-in-one freezer design, no additional backup freezer or its additional footprint and energy use is necessary. The cool safe refrigeration compressors feature innovative refrigerant feedback processes to reduce compressor temperature, extending compressor life and minimizing heat output. Reply Card #4897

Spectrometer Ocean Optics has launched a family of aberration-corrected holographic concave diffraction grating spectrometers that delivers low stray light, high throughput and excellent thermal stability for applications ranging from absorbance measurements of optically dense solutions to fluorescence measurements in solutions and powders. Torus is a compact visible spectrometer (360-825 nm) with greater throughput and less stray light (~0.015% at 400 nm) than planar-grating and other miniature spectrometers. A flat field optical design and a reflective holographic concave grating disperses light; the concavity of the Torus’ grating reflects and focuses the light and the grating groove pattern disperses the light. The toroidal nature of the grating further enhances the aberration correction and efficiency. For convenient experiment setups, the Torus Spectrometer interfaces to a computer via its USB port and couples to Ocean Optics accessories. The Torus model is available with a variety of slits, filters and other optical bench accessories for optimizing configurations. Free-space optical coupling is accommodated with standard C-mount adapter.

Spectrometer Thermo Scientific introduces the iCAP 6200 inductively coupled optical emission spectrometer (ICP-OES). Designed for a wide variety of applications, including food and consumer safety, environmental, mining and WEEE/ RoHS testing, the iCAP 6200 ICP-OES is a powerful and cost-efficient trace elemental analysis solution. The iCAP 6200 ICPOES now incorporates a wider wavelength range of 175-847nm. This enables users to measure a broader range of analytes during multi-element analyses and access more sensitive wavelengths for improved analyte detection capability. The instrument is a simple, multi-element analysis solution for laboratories that perform routine analyses of up to 100 samples per day. With its enhanced specifications, the iCAP 6200 can now measure sulfur as part of a multi-element method in addition to the most sensitive mercury, thallium, carbon, tin, phosphorous, arsenic and iodine wavelengths. Enhanced analytical performance is combined with award-winning design features that reduce running costs and simplify operation. Compact, the iCAP 6200 ICP-OES requires minimal bench space and ensures excellent signal stability, analyte detection and wide dynamic range. Reply Card #4899
