Equine Slim is a bio-compatible, polymer equine microchip that comes pre-loaded in sterile syringes ready for implantation and designed for ease-of-use. The thin 14 gauge needle allows for smooth and gentle implantation with minimal penetration force. Each implantation is as small as a thin grain of rice, weighs a fraction of standard glass microchips and contains a permanent ID code that is unique to that animal. The ISO-compliant ID can also serve as verifiable proof of ownership for competitions and personal insurance.
