Welcome to SciK9®, the home of the TADD® (Training Aid Delivery Device) Containment System.

Training aid storage and odor delivery in one convenient containment.

Created for the US Army and designed by canine trainers and scientists, the TADD® containment system can bring your canine training to the next level.

What is the TADD®  containment system?
Most simply, it's a container that lets the odor of your training aid out, but not the training aid. But it's way way more than that... Read below to see what the TADD
® containment system is capable of and how it is revolutionizing scent detection training.


Design considerations ensure that all components of the TADD® containment system are:

  • NASA Outgassing Compliant* to be extremely low odor, so the only scent you train your dog on is the training aid

  • Inert and highly compatible with most training aids

  • Rugged enough for daily use and training

  • Capable of being decontaminated and deodorized of human scent or environmental odors



  • Glass or Plastic material available.

  • 4 Sizes Available*:

    • Small​

    • Medium

    • Large

    • Extra-Large

  • ​*Note: Plastic jars are only available in the small and medium size.

  • Transparent - Allows you to keep a visual on your training aids to ensure they are not decomposing or crystallizing.


  • Comprised of a gas-tight chemical-resistant gasket, hydrophobic and oleophobic membrane, and a custom polypropylene membrane holder with a safety grid to prevent membrane puncture.

  • Safely contains liquids, oils, solids, small particulate, and hazmat



  • Comprised of a gas-tight chemical-resistant polypropylene lid.

Comparison of the TADD® Containment System to Current Training Aid Containment




*All materials pass the NASA low outgassing test (ASTM E595). Developed by NASA to screen low outgassing materials for use in spacecraft, the test determines the volatile content of material samples placed in a heated vacuum chamber. If the collected volatile condensable materials (CVCM) is < 0.1 % and total mass lost (TML) is <1 %, then the material passes the NASA criteria for low-outgassing.

Where can I use my TADD® containment system?

Let your imagination run wild! We and our incredibly creative customers have buried the TADD® in sand, soil, and rubble piles. They have submerged the TADD® in lakes, rivers, and toilet tanks. And, of course, they've performed all of the traditional operational hides in vehicles, warehouses, luggage, cargo, buildings, open areas, and medical settings

Can't bring your actual training aid into your operational environment? Use the Whatman Filter Paper!

Worried about your TADD® containment system getting damaged? Use the Stainless Steel Scent Can!

Need to extend the range of your hide locations high up or low down? Use the Hook Magnet and Disc Magnet with the Stainless Steel Scent Cans!

Want to vary the amount of odor coming off of your training aids? Use the Odor Restriction Cap Set to help decrease your dogs limit of detection (LoD). 

Have an extremely stinky training aid and concerned about it contaminating your other training aids? Combine the TADD® with a Metalized Odor Barrier Bag as secondary containment to ensure you preserve the integrity of your training aids. 

No matter what your concerns are, the TADD® containment system by SciK9® can address them using scientifically sound methods designed to incorporate best practices and treat your canine's olfactory system with the respect it deserves.
