The AccuMAX Series of digital radiometers/photometers provide accurate readouts for ultraviolet (UV) irradiance, visible illuminance, and luminance light readings. The readout units are specially calibrated for use with a full line of interchangeable sensor detectors. When equipped with a sensor detector, the AccuMAX readout unit can satisfy nearly any laboratory or life science application, including fluorescent inspection and UV dosing. Single-wavelength sensor detectors are available in both standard range and extended range. The standard range provides UV readings from microwatts to milliwatts and the extended range provides measurements from milliwatts to watts. All sensors are ideal for checking the intensities of fluorescent UV tubes and HID UV bulbs. AccuMAX meters are microprocessor-controlled with software-driven functions. The readout unit has user-customized settings to work with a wide variety of interchangeable sensor detectors. Powered by two 9 V alkaline batteries, the readout unit is lightweight and portable with a large, easy-to-read LCD screen


The new Orbitor BenchTrak is a fully customizable plate mover with quick-connect modules. The Orbitor BenchTrak significantly extends the functionality and versatility of the renowned Orbitor RS plate mover, providing a fully customizable automation solution that fits into existing laboratory space. Multiple Orbitor BenchTraks can connect to form complex system layouts, and a range of "click-in" components, such as instrument loading platforms, mezzanines, guarding, and microplate stores, can be easily incorporated to address almost any workflow requirement. The PC-driven Orbitor BenchTrak features the Momentum 3 software, which enables users to configure it for a wide variety of benchtop workflows including sample preparation, ELISA, nucleic acid and protein purification, cell or biochemical assays, real-time polymerase chain reaction, and next generation sequencing. A new LOCaMotion touch screen teaching wizard guides users through the configuration process. The Orbitor BenchTrak empowers the user to create and customize a benchtop workstation that is ideal for automating their unique workflow applications.


With clean lines, a smaller footprint, and a host of new features to benefit the operator, the new YSI 2900 advanced biochemistry analyzer is a perfect combination of YSI's trusted enzyme electrode technology with everything users would expect. Able to handle the widest range of sample containers, up to and including a 96-well plate, the YSI 2900 produces a result in approximately 60 seconds for glucose, lactate, ethanol, and 12 other important bioprocess parameters with accuracy comparable to HPLC. The icon driven user interface and built-in training videos make operation simple, while the up-to-date hardware ensures a rapid, highly accurate result with robust sampling of viscous samples or high cell counts. The system's built-in sample handling capability eliminates the need for a separate autosampler and enhanced connectivity options including USB and Ethernet, ensure fast and straightforward data downloads.


The Milliplex Map EpiQuant Receptor Signaling Pathway panel has been designed for assessing the functional states of cells by profiling a range of receptor signaling pathway proteins. The Luminex-based approach enables the profiling of 26 analytes including total and phosphorylated receptor tyrosine kinases, nonreceptor tyrosine kinases, cellular kinases, and a phosphotase with picomolar sensitivities. Users can easily design customized panels by selecting only the analytes of interest. Site-specific, quantitative measurements with picomolar sensitivity support diverse sample types and many research and drug discovery applications. Compared to traditional detection techniques such as Western blots, mass spectrometry analyses, and radioactive phosphorylation assays, the EpiQuant Receptor Signaling Pathway panel provides faster results, increased assay throughput, and specificity. The new panel provides highly validated and characterized immunoassay antibodies, all necessary reagents, and optimized protocols.


A new, highly sensitive two-step polymerase chain reaction (PCR) assay can be used to detect several important Pospiviroids known to cause significant damage in ornamental, citrus, and solanaceous crops. Agdia's own conventional two-step reverse transcriptase PCR (RT-PCR) is ideal for testing crops subject to phytosanitary restrictions and requirements. The Agdia designed RT-PCR can detect the presence of these destructive pathogens at levels 10 times lower than possible with commonly used single-step RT-PCR. Fast and highly reliable, the Agdia Pospiviroid PCR will screen for the following viroid infections: Potato spindle tuber viroid (PSTVd), Tomato chlorotic dwarf viroid (TCDVd), Tomato apical stunt viroid (TASVd), Tomato planta macho viroid/Mexican pepita viroid (TPMVd/MPVd), Chrysanthemum stunt viroid (CSVd), and Citrus exocortis viroid (CEVd). Agdia's Pospiviroid primers are not degenerate and allow for highly specific sequencing matches, when needed.
