Tissue Sectioning Equipment (Histology)

The Imaging Facility is equipped with a number of tissue sectioning tools to prepare samples prior to microscopy. The Facility has very limited capacity to provide histology services, but full training on all of the equipment is available, with expert assistance on-hand to support inexperienced users.
