This is a Bio-Rad Radiance confocal microscope mounted on a Nikon E800 manual upright microscope stand. You can use this microscope for imaging slides and for specimens that can only be imaged in open chambers in aqueous media (e.g. tissue, pupae/embryos, fish). The optional water dipping lenses have working distances in the order of 2 mm. Live mammalian cells can be imaged if the imaging chamber can be inverted so the cells are upside down. There is an optional heated stage adapter for warming the specimen but there is no CO2 supply so the chamber must be sealed to prevent pH change stand. There are three lasers with with six laser lines but there is no 405 nm laser, so you cannot image DAPI or Hoechst. The confocal has three GaAsP detectors for high sensitivity imaging of poorly fluorescent specimens or at low laser power. FRAP and other photo-stimulation experiments are possible Training & BookingSpecificationsObjective LensesStandard Objective Lenses | Magnification | Type | Immersion | NA | DIC | WD (mm) |
