This pad is to be used in our BIO-Case for the warming of your AI equipment prior to its use. It was designed to help you avoid “cold shock” to the semen and increase technician’s conception rates. Tri-level heating, specific to the ambient temperature conditions, make this the only safe and proven warming unit. In most cases (above 32ºF) the 1st setting would be a most common choice. In cases of below freezing temperatures (below 32ºF) the 2nd setting, and the 3rd used in cases of extreme cold (below 0ºF).
