Training Bloods were developed in order to fill a need to eliminate the possibility of pathogens originating from the use of human and non-human blood in the classroom or lab. Spatter blood was formulated to mimic the physical properties of fresh human blood. Excellent for demonstrating the properties of fresh blood spatter when dripped, poured, or splashed onto any surface. Ideal for training. Provided as 8 oz. premixed bottles.
