The IMI-500 is a miniature glass-encapsulated ‘read-only’ transponder. Scanned by an appropriate BMDS™ reader device, the IMI-500 transmits its 10-digit alphanumeric code, making animal identification quick, easy, and fail-safe. The IMI-500 is identical to the classic IMI-1000, except in size. Approximately 8 millimeters in length by 1.4 millimeters in diameter, the transponder features a new smaller size for specific applications. Compatible with BMDS™ reader systems that read the IMI-1000, IMI-500 features an amazing read distance of 3 inches. 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-500 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.
