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. Synthetic blood was formulated to mimic the chemical reactions to common chemical tests for blood such as Luminol and Phenolphthalein, and protein enhancement techniques such as Leucocrystal Violet or Amido Black. Ideal for training. Provided as 8 oz. premixed bottles.
