    Brief

    Laboratorie-, optisk- og presisjonsutstyr

    ETH Zürich - Abt. Procurement & Export Services needs a new scanning electron microscope (SEM) equipped with a field emission gun, secondary electrons detector (SE) and high-performance backscattered electron detectors (BSE), and a state-of-the-art large area (≥ 100 mm2) energy dispersive spectrometer (EDS) for imaging and quantitative analysis in geological samples. The instrument should have a large chamber to allow a minimum of 3 petrographic thin sections and 6 one-inch epoxy round mounts, and be programmable for automated quantitative EDS analyses lasting over 24 hours. The main goal is to provide precise and accurate quantitative analyses by EDS using a rigorous quantification protocol. The delivery location is Zürich. Offers for panchromatic and/or entry-level monochromatic cathodoluminescence detectors are also welcome. The award criteria are based on quality.

    About the bid

      The Institute of Geochemistry and Petrology at ETH Zürich is seeking to upgrade its existing analytical scanning electron microscope (SEM) for a new SEM equipped with a field emission gun, secondary electrons detector (SE) and high-performance backscattered electron detectors (BSE), and a state-of-the-art large area (≥ 100 mm2) energy dispersive spectrometer (EDS). Among several options, we welcome offers for panchromatic and/or entry-level monochromatic cathodoluminescence detector. The main goal of this instrument will be to provide precise and accurate quantitative analyses by EDS using a rigorous quantification protocol that includes the use of reference materials and a full matrix correction (ZAF, phi-rho-z, or equivalent). The instrument should have a large chamber to allow a minimum of 3 petrographic thin sections and 6 one-inch epoxy round mounts. It should be programmable so that we run series of >24 hours of automated quantitative EDS analyses. For further details, please refer to the specifications.

      Laboratorie- og analyseutstyr

      Beschaffung eines cryo-konfokalen Fluoreszenzmikroskops

      Das Institut für Biochemie und Molekulare Medizin benötigt ein fabrikneues kryo-konfokales Fluoreszenzmikroskop (kryo-kFM) zur Integration in einen kryo-CLEM-Workflow für zelluläre Kryo-ET und In-situ-Strukturbiologie. Das Mikroskop soll mindestens vier Fluoreszenzkanäle (Laser) und ein hochsensitives, hochauflösendes Detektorsystem für die Konfokalmikroskopie besitzen. Es muss zwischen Konfokal- und Widefield-Fluoreszenzmikroskopie wechseln können, mit entsprechenden Lichtquellen, Filtern und Kamera ausgestattet sein und über mindestens ein kryo-kompatibles Luftobjektiv mit hoher numerischer Apertur und mindestens 50-facher Vergrösserung verfügen. Eine kryo-Stage, die Proben (kryo-EM Grids mit vitrifizierten Zellen) bei < -150°C laden, abbilden und entladen kann, ohne Temperaturerhöhung oder Kontamination, ist ebenfalls erforderlich. Die kryo-Stage muss mit gängigen kryo-EM Grids und AutoGrids kompatibel sein und in die Software-Benutzeroberfläche des kryo-kFM integriert sein. Hohe Bildgebungsqualität, Robustheit bei der Probenbergung und Benutzerfreundlichkeit sind besonders wichtig. Die Lieferung erfolgt in Bern.
