Small 8mm × 1.4mm FDX-A implantable PIT tag for individual identification of Australian wildlife, lab animals, zoo species, and small mammals — supplied as a sterile 10-pack with single-use needles.

About this product

The Trovan ID100 Midi is a small glass-encapsulated FDX-A microchip / PIT tag designed for individual identification of small Australian wildlife, zoo and research animals. At just 8mm long and 1.4mm in diameter — substantially smaller than the conventional Trovan ID100C (11.5mm × 2.1mm) — it's the size of choice when the animal is too small for a conventional chip.

Ideal for

• Small native mammals — antechinus, dasyurids, native rodents, juvenile possums and gliders
• Microbats and small bird species — often combined with leg-band or surgical-adhesive PIT-tagging
• Reptiles and frogs — skinks, geckos, small monitors, treefrogs
• Juvenile and small fish — including freshwater natives where a Nano isn't required
• Zoo studbook animals — small primates, exotic small mammals, juveniles of larger species
• Laboratory research animals — rats, mice, guinea pigs, rabbits, ferrets

Why Trovan FDX-A (not FDX-B / ISO)

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 (or at all) 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 requires the dedicated Trovan IM200 (1.4) Midi syringe implanter (re-usable, sold separately). The needle is the only single-use component. Each 10-pack includes 6 adhesive labels per chip showing the microchip number and barcode for record-keeping.
