Each transponder is pre-loaded into a disposable implanter, sterilized by EO gas and individuallypacked with 6 adhesive bar-coded labels. The syringe is designed for maximum ergonomiccomfort (thanks to its lugs for the index and middle fingers).It allows the most natural approachand body language during the implantation process (it can be easily held in one hand withoutfrightening the pet) and it comes ready to use (no assembly required). Plus, its no-return clicksystem is an additional safety feature for the practitioner: it blocks the injector in the‘‘depressed position’’ which stops the transponder being sucked back into the syringe by thepiston. This little ‘’click’’ indicates that the transponder has been correctly positioned.
