Viso Guard Gel has been developed for cases where high penetration and odor control are needed. Viso Guard Gel is a surface embalming material of high viscosity designed to cling very well to tissue. It contains proven preservatives, deep penetration agents, and gas and odor control chemicals. As a result, it will deodorize and preserve putrid tissue as well as areas of the body that arterial embalming may have missed.
