IMI-400 Transponder (Read-Only)

Injected with a syringe-like action, IMI-400 transponders are pre-loaded in a disposable needle assembly. The ergonomic design of this one-piece tool fully integrates the handle, stainless steel needle, and drive pin. Packaged in boxes of 100, the patented applicator loaded with one transponder is processed through an ethylene oxide cycle for sterilization. No assembly or loading is required. Pick one up, remove the needle cap, implant the transponder, and dispose of the injector. All in one clean operation.
​The IMI-400 is compatible with BMDS™ DASHost software which facilitates importing data into widely used applications such as Excel, offers a menu-driven solution to collecting data from various sources (scales, calipers, etc.) and provides an ingenious method to receive, map, control, and route data. Despite its small size, it has a read distance of 3 inches, making it suitable for universal applications. Designed for harmless implantation, BMDS™ Micro-Transponders is the most convenient, humane, reliable, and cost-effective method for automated animal identification.

The new 6 mm IMI-400 is a miniature glass-encapsulated ‘read-only’ animal transponder. Scanned by an appropriate BMDS™ reader device, the IMI-400 transmits a unique 10-digit alphanumeric code, making animal identification quick, easy, and fail-safe. The IMI-400 is identical to the IMI-500 and classic IMI-1000, except in size. Now only 6 millimeters in length by 1.4 millimeters in diameter, the transponder features a smaller size for specific applications. Compatible with BMDS™ reader systems that read the IMI transponders, the IMI-400 features the same amazing read distance of 3 inches or 8 cm from the reader to the animal. Designed for harmless implantation, BMDS™ transponders are the most convenient, humane, reliable, and cost-effective method for automated animal identification. You can even retrieve data decades after a study ends if you remove the transponder with a tissue sample and place it into long-term storage, in cold or liquid preservative.

About Parylene Coating

Parylene coating will encourage tissue encapsulation to prevent transponder migration. The coating forms a surface that allows for tissue fiber adhesion within the animal subcutaneous layer thereby bonding around the IMI-400 transponder holding it in place. Parylene coatings are used in many animal applications as well as for human medical use. Examples are pacemakers, forceps, catheters, stents, needles, implantable devices, and many more have a parylene coating. The coatings have been proven to prevent rejection of the item and speed up the bonding process with the tissues. Parylene is fully bio-compatible. Parylene has been FDA-approved (with USP XXII Class VI biocompatibility rating) and is safe for use within the human body. Parylene has also passed the ISO10993-1/FDA biocompatibility evaluation tests for cytotoxicity, system toxicity, hemocompatibility, sensitization, and intracutaneous reactivity.
