Telescope Spectrograph Optics
Benefiting from a unique facility where temperatures remain constant year-round and vibration is practically nonexistent, Optical Surfaces is able to routinely produce and test demanding telescope spectrograph optics (aspheres, flats, lenses, mirrors, and prisms) that stretch the limits of conventional optical fabrication techniques. Using a spectrograph, researchers can study the chemical and physical conditions that exist in a cross-section of space. Combined with a land- or space-based telescope, a spectrograph can reveal valuable information about the spectral distribution of light from a distant astronomical object. Optical Surfaces maintains a range of interferometers that allow one-to-one testing of even the largest-diameter spectrograph optics. Topographic and fringe analysis provides precise testing of surface roughness and confirms the wavefront of various surface forms. Operating a rolling program for calibration of test optics (where possible) to national standards and production approval to ISO 9001-2015 ensures that our optics are second to none.
Biotinylated Antibodies Quantification Kit
Quantification of biotin after biotinylation of antibodies (or other proteins of interest) can be an important step for development, manufacturing, or quality control of immunoassays. Traditional biotin quantification methods, such as the HABA (4′-hydroxyazobenzene-2-carboxylic acid) assay, suffer from long and complex hands-on protocols as well as accuracy and reproducibility issues. The Biotin Q Conjugation Kit (with inbuilt quantification) from Expedeon provides immunoassay developers with a short and simple hands-off protocol, along with accurate and reproducible measurements. Spectrophotometric readings can be made directly on conjugated antibodies or other proteins of interest after biotinylation.
Silicone Lids
Instead of using aluminum foil or plastic wrap to cap beakers and flasks, scientists can now use KIMBLE Silicone Lids. The lids stretch and conform to beaker tops for a tight, secure seal providing a safer closure. Available in three sizes and colors, the user-friendly lids fit on beakers, flasks, bottles, and cylinders. The stretchy silicone material creates a seal on spouts, beaded tops, or threaded necks on glass or plastic vessels. Resistant to heat and chemicals, the lids are designed with tabs so they are easy to put on or take off, even when wearing gloves. Dishwasher-safe and reusable, the lids are a popular, sustainable solution for environmentally conscious labs.
Vacuum Ultraviolet Spectroscopy Workstation
McPherson offers two new deep-UV spectroscopy workstations to facilitate teaching and experimentation in vacuum and ultraviolet physics. The workstations are ideal for spectroscopy experiments in the vacuum ultraviolet regime, potentially advancing quantum information science and engineering. There are two experimental kits available: diagnostic and analytical. The diagnostic system equips the spectrometer with a sensitive charge-coupled device (CCD) detector and can be used to measure spectral emission of laser interaction, high-harmonic generation, plasma formation, luminescence, and fluorescence. The analytical system comes with a tunable deep-UV light source, rather than the CCD detector, and is ready to explore Einstein’s photoelectric effect, one of the earliest predictions of quantum physics. The configuration is also good for measuring transmission, photocathode response, and reflection. Key features of these workstations include a versatile and convenient spectrometer; filters; an open-concept, high-vacuum sample chamber with a built-in optical breadboard; and an easy-to-use vacuum pumping system. Systems may also have a deep-UV light source. Students and experienced researchers will have more time to consider setups and interpret results when using these systems.
Plate Sealer
The Thermo Scientific ALPS 5000 has been developed to increase the efficiency of the heat plate-sealing process and offers maximum flexibility to support high-throughput applications, from polymerase chain reaction and high-performance liquid chromatography to NGS, compound storage, and flow cytometry. It facilitates easy, tool-free foil loading and does not require the use of adapters to change between different plates. The system is operated via a large, intuitive touchscreen with a modern user interface that allows for precise control over sealing parameters, ensuring repeatability while including programming parameters for integration into automation or robotic workflows. Users can program sealing time, temperature, and pressure parameters to suit their specific requirements. The instrument offers fast sealing times of up to four plates per min and features a compact footprint to save valuable bench space. Furthermore, the ALPS 5000 has been equipped with an Eco Mode, which triggers a temperature reduction down to 30°C when the system has been inactive for a prespecified amount of time, allowing for considerable energy savings.
Robot-Compatible Solvent Removal Workstation
The new UltraVap Mistral XT 150 from Porvair Sciences provides unmatched, automated drydown of organic solvent-based samples in tubes and microplates up to 150 mm in length. Designed for easy integration with linear laboratory robots, the workstation uses a sample shuttle that can serve and retrieve long tubes or microplates from the deck of Perkin Elmer, Tecan, Hamilton, and Beckman liquid handlers. Controlled via an intuitive color touchscreen, the XT 150 comes complete with clear safety side screens and full integral fume management. Installation requires only connection to a gas supply and mains electricity. Safety of solvent removal operation is ensured, as this compact, CE-marked unit fits into all fume cupboards.
