Preserved cow organs are perfect for use in biology and anatomy classroom studies. Cow organs are generally larger than other mammal organs which allow students to easily identify structures. At Carolina you will find cow eye, cow heart and cow spinal cord specimens. You have a choice of standard formalin preserved cow organs or Carolina's Perfect Solution® preserved cow organs. Organs preserved in Carolina's Perfect Solution® are more lifelike in color and texture, have no formalin order or dangerous off-gassing.
