Avoid the health risks and compliance costs of formalin by using our formaldehyde-free solution, Prefer. This fixative provides the morphological detail of good aldehyde fixation while preserving high levels of immunoreactivity. The principle ingredient, glyoxal, is non-volatile,so there is no inhalation risk. In addition, it is non-sensitizing and non-carcinogenic. Waste fixative can be discarded down the drain in most localities. Each makes 5 gallons of dilute Prefer fixative.
