Trimming of wood segments and cores
Coarse preparation wood surfaces
A precision saw (Buehler Isomet 5000) was modified by our GFZ workshop for dissecting thin cross sections from wood cores or wood segments.
WSL Sliding microtome
UV-Laser Microdissection Microscopes
For high resolution intra-annual investigations of tree rings variuos microtomes as well research microscopes with UV-laser dissection devices are being used. This allows to prepare, dissect and collect samples, e.g. tree-rings and parts thereof of micrometer size/thickness.
Tree-rings of >0.2mm width are being dissected utilizing binoculars (Nikon)
