The tree-ring laboratory at the Gutenberg-University in Mainz offers the opportunity to sand wood samples, prepare micro cuts and measure tree-ring widths. It includes three Lintab measuring devices and 20 additional binoculars, which can be used to teach classes including 20-30 students. An X-ray radiodensitometry device will be installed in the laboratory to facilitate maximum latewood density measurements for palaeoclimatic analyses. The laboratory includes equipment to monitor tree-ring growth and collect material from living trees and historical wood structures.
