BioGnost’s BioMount Aqua synthetic medium for covering microscope sections and mounting medium for cover glasses provides expected transparency of sections. It also provides a refractive index similar to refractive indexes of a glass slide and cover glass, which in turn does not lead to unwanted refraction of light. This in turn results in a clear and detailed image of the section. It is used for processing sections tested for enzymes and lipids, i.e. for testing samples that must not be dehydrated through a series of ascending alcohol solutions and be cleared using xylene and xylene substitutes. A small amount of BioMount Aqua medium should be applied to the test sample in order to create a fixed permanent preparation (along with the solvent evaporation).
