The Cervical Dislocator is a completely humane and efficient means of sacrificing laboratory rodents bloodlessly. Evidence indicates that the brain stem is terminated instantly by a blow from the metal bar.
There is no external wound, and so there is no blood to clean up, and no smell of blood to alert remaining animals. Pathogens or viruses are not spread. Blood and internal organs remain uncontaminated.
When used with the plastic restraint cones (No. 51361), the animal can be effectively and safely restrained during transfer between cages or through all necessary handling. The 5 cm opening is sufficient for most laboratory rodents. A 6 cm model (#51365) is also available.
