Microscopy Lab

For the analyses of rock, biofilm and tissue sections we apply a broad spectrum of microscopic techniques reaching from conventional thin section petrography to deconvolution epifluorescence microscopy of molecular probe-labeled microtome sections.

Sectioning

  • Preparation of rock thin sections for petrography and microfacies analyses up to 10 x 15 cm in size
  • Hardpart microtome sectioning of resin-embedded biofilm and tissue samples
  • Sectioning of paraffin-embedded samples using a rotary microtome

Light Microscopy

  • Upright epifluorescence microscope with interference contrast and deconvolution system (imaging and signal detection with Visicam-Color CCD camera, Metamorph image analyses and EPR deconvolution software)
  • Inverted epifluorescence microscope with ratio imaging (filter wheels, CCD-camera Coolsnap HQ Monochrome, Metafluor software)
  • Cathodoluminescence microscope
  • additional epifluorescence and polarizing microscopes

Electron Microscopy

  • Scanning electron microscope with element imaging device for standard investigations
  • A field-emission scanning electron microscope (FE-SEM) with cryo-station and EDX
