NuVision Technologies (Beaverton, Ore.) launched the 60GX Wireless Stereoscopic Glasses into the international marketplace this month. These glasses are unique in their ability to deliver stereo performance at an affordable price. NuVisions' patented high-speed pi-cell technology allows crisp, clear, and flicker-free images over the entire display. The lightweight glasses can be installed in seconds, fit over prescription glasses, and are fully compatible with all of today's stereo-ready workstations, PCs, and software. They are also compatible with IR emitters from StereoGraphics. Primary users of these glasses are researchers in pharmaceutical and biotechnology companies, specialty chemicals, petrochemical and polymer companies, and in academia. The glasses carry a retail price of $249 (including infrared emitter), come with a two-year warranty, and deliver 600 hours of battery operation. For more information call 1-800-920-9327. Vision Engineering (New Milford, Conn.) recently introduced the new COBRA stereo microscope system with proprietary Expanded Pupil (EP®) technology, which incorporates enlarged eyepieces for fatigue-free viewing. EP viewing increases the distance between the operator's eye and the eyepiece, allowing freedom of head movement in all three planes of motion. Coupled with superior optics, EP viewing enables the user to comfortably view high-resolution images without the eye, neck, and back fatigue associated with conventional eyepiece microscopes. The COBRA features zoom magnification up to 160X with a working distance to 312 mm. COBRA's refractive disk technology and straight optical path improves resolution at high magnification, as well as depth of field and color rendition. A wide rang of mounting, lighting, and photomicrography options are available. For more information call 1-800-644-7264. Beckman Instruments, Inc. (Fullerton, Calif.) introduces the Multimekä 96 Automated 96-Channel Pipettor. Previously sold as the MultiPetteä in the United States by the SAGIAN Division of Beckman, this liquid handling system has been improved to meet the requirements for CE, UL, and C-UL certification. The Multimek 96 is ideal for platewise microplate pipetting applications including microplate replication, reagent addition, and full-plate serial dilutions. It easily handles transfers between 96- and 384-well plates on the same work surface and can be configured for stand-alone operation or integrated into automated systems. The Multimek includes user-friendly Multimek Pro software that provides quick productivity through easy programming. The software is Windowsä-based and adapted from the SAMIä software environment developed by SAGIAN for robotic microplate systems. Intuitive flowcharts are used to program method steps, and a variety of pipetting parameters may be set at the user's discretion. For more information call 1-800-742-2345. Outside the U.S. call 1-714-773-6707. The Turner Designs TD-700 Laboratory Fluorometer, in combination with Molecular Probes' new RiboGreen RNA quantitation reagent, provides an ultrasensitive method for RNA quantitation in solution. This assay can detect as little as 1 ng/ml RNA, which is 1000-fold more sensitive than the most commonly used technique of measuring nucleic acid concentrations by absorbance at 260nm. Even in the presence of several compounds commonly found to contaminate nucleic acid preparations, the linear RNA assay range extends across three orders of magnitude. Although the RiboGreen reagent also binds to DNA, pretreatment of mixed samples with RNase-free DNase can be used to easily generate an RNA selective assay. The TD-700 Fluorometer is a compact, easy-to-use benchtop instrument equipped with a multi-assay filter cylinder and multi-point calibration capability. The instrument is designed for quick, reliable, and accurate measurements of RNA, DNA proteins, GFP, and a variety of other fluorescent compounds.

This new system provides the ultimate tool to easily identify and quantify over 200,000 spots in numerous high-density grid images. The positives or negatives can be exported to the picking robot to facilitate follow-up experiment. The HDG Analyzer accommodates all rectangular grid layouts and makes it very easy to create the reference matrix. A constellation-mapping algorithm requires only three anchor points on a reference image tin order to accurately overlay multiple study images. This method, unlike rigid grid methodologies, compensates for any distortion or skewing that may occur within a sample array. Using proprietary algorithms, the software quantifies the actual spot, not only grid locations. After quantification, clones can be sorted based on the amount of hybridization. Powerful spot database queries can filter information based on the existence of spots, quantitative ratios of matched spots, spot integrated intensities, area and user-defined spot characteristics. The HDG Analyzer supports direct image acquisition, but can also import TIFF format images files from various sources including storage phosphor devices and fluorescent imagers, and Bio Image's soon-to-be-released Biospace Beta ImagerTM direct detection system. For more information, contact Bio Image at 800-246-4624. Loading plastic pipette tips can be frustrating and time consuming. Bellco Glass, Inc. developed the "Tipster" to solve those problems by eliminating the need to manually load plastic pipette tips into tip containers. The "Tipster" automatically loads six templates of tips per container, which are then transferred by use of the pipette tip picker, to tip holders. The "Tipster" can be utilized in cell culture, genetic, chemical and medical laboratories that perform blood serum tests, as well as any laboratory that applies plastic tips to perform tests and scientific protocols. This patented device offers a peg and grommet attachment to fit BellcoOrbital Shakers, is made with lightweight materials, and assures impact resistance for safe operation. This unit also accommodates most brands of tips, and is easy to maintain. The "Tipster" includes one Tipster box, a set of six templates, a collection tray, a template holder, one picker and a holder, and an anti-skid frame that can be mounted temporarily or permanently.
