Conventional 11.5mm × 2.1mm FDX-A implantable PIT tag for Australian wildlife, zoo, and research animals — supplied as a sterile 10-pack with single-use needles. Best read range of the ID100 range.

About this product

The Trovan ID100C is the conventional-sized FDX-A microchip / PIT tag — 11.5mm long and 2.1mm in diameter. It's the standard chip used in larger Australian wildlife, zoo studbook programs, and laboratory research where the Midi (8mm × 1.4mm) isn't required and best read range is preferred.

Ideal for

• Larger Australian mammals — possums, gliders, bandicoots, quolls, Tasmanian devils, wombats
• Larger reptiles — pythons, larger monitors, freshwater turtles, larger lizards
• Larger bird species — raptors, larger waterbirds, parrots and cockatoos
• Zoo studbook animals — medium and larger species, primates, hoofstock
• Laboratory research — adult rabbits, ferrets, primates and similar
• Long-term monitoring projects where read-range matters at remote monitoring stations

Why Trovan FDX-A

The Trovan Unique ID100 (FDX-A) protocol is the most widely-used implantable RFID system in Australian wildlife research, zoo studbook management, and laboratory research. FDX-A tags work with the full range of Trovan remote monitoring systems — pop-hole antennas, nest-box readers, swim-through tunnels, and weigh-scale integration — whereas ISO FDX-B tags often can't be read reliably by fixed antenna systems.

Note: Trovan FDX-A microchips are NOT registered with Central Animal Records and are NOT suitable for companion dogs, cats or horses in Australia — Australian legislation requires ISO FDX-B microchips for companion animals.

Format and supply

Each microchip is pre-loaded into an individual single-use sterile needle. Implantation uses the re-usable Trovan IM200 syringe implanter (sold separately). Each 10-pack includes 6 adhesive labels per chip showing the microchip number and barcode for record-keeping.
