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


Training aid storage and odor delivery in one convenient containment.

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

What is the TADD?
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 is capable of and how it is revolutionizing scent detection training.


Design considerations ensure that all components of the TADD 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

  • Cleaned according to EPA standard methods

  • 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.

*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.

We listen to our end-users and are constantly collecting feedback in order to improve our product, educate ourselves on the capabilities and limitations of the TADD, and share this knowledge with the K9 community. Below is a list of known issues, what we are doing about it, and feedback from the field has made us aware of the following potential issues that we would like to disclose and share with our end-users:

  1. Nosework essential oils (birch, anise, and clove) are incompatible with the TADD gaskets. These oils are highly reactive and have very specific packaging/containment requirements. We are investigating this issue in the laboratory and experimenting with an alternative gasket material. HOWEVER, the TADDs are fully compatible with the National Association of Canine Scent Work (NACSW) style essential oil odor absorption method, using 100% cotton swabs, cut in half and scented with one of the three essential oils: Birch, Anise, and Clove.

    • SOLUTION: Use the odor absorption method of presenting essential oils. AND... standby as we prototype the TADDpole (TM) miniature TADD that will be compatible with essential oils.

  2. The plastic TADD jars can become deformed in extreme temperatures (e.g. >150F/65C). These temperatures can be reached inside vehicles during hot days. 

    • WORKING ON IT: We are exploring other jar types that may have better temperature tolerances while also meeting our strict low out-gassing requirements. In the meantime, keep your plastic TADDs out of the extreme heat.

  3. During water submersion hides, at some depth beyond 9 feet (2.75 meters), the TADD membrane may become compromised and slip off of the gasket into the TADD jar due to hydrostatic pressure. We are experimenting with different methods of submerging TADDs beyond those depths while maintaining the TADD's seal.

    • SOLUTION: When submerging the TADD at >3m (9ft) depths, please do the following: invert the TADD so the membrane is facing down toward the bottom of the body of water, and make sure the TADD submerges and resurfaces slowly to allow for equilibration time, if possible.

  4. Some of the metallized odor barrier bag (SKU: MOBB) seals have been ripping after repeated use. We are exploring using other brands, sources, and seal technologies of MOBBs and will update our product list if/when we find a superior offering. 

    • FIXED: We have found a metallized odor barrier bag with a durable, child-resistant (ASTM D3475) double seal. End-user feedback has been really positive, noting that the bags withstand hundreds of openings. Thank you to our beta testers!

Who is using the TADD and What are they putting in it? 

  • LEO: explosives, narcotics

  • SAR/HRD: human remains, blood, bone

  • Conservation: scat, bedding, fur, bats

  • Pest: bed bugs, scat, eggs

  • Medical: clinical samples, COVID-19 patient samples, biopsy tissue

  • Arson/Fire Inspection: accelerants

  • K9 Vendors & Trainers: ScentLogix (TM), Precision Explosives (TM) training aids

  • Specialty Trainers: Human scent samples

Where can I use my TADD?

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 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 Metallized Odor Barrier Bag as secondary containment to ensure you preserve the integrity of your training aids. 

No matter what your concerns are, the TADD 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.

What Have you Done for Me Lately?

We're constantly improving our products and processes to bring you the best scent detection tools. We also listen to our clients and take your feedback seriously. To that end, we are working on quite a few initiatives.


  1. TADDpole (TM), a smaller version of the standard TADD, better suited for operational hides and nose work essential oils. 

  2. TADD Sample Collection Kits (TADD SaCKS) for patients with medical alert dogs in training. These kits will include the TADD and protocols for sample collection, preservation, and storage, thus lowering the burden on patients and their families while undergoing the sample collection process. Additionally, the kits will aid canine training by helping to standardize the process for how patient samples become canine training aids for the deployment of diabetes, epilepsy, and other medication detection & alert dogs.

  3. The SciK9 High Hazard Explosive Powder Odor Delivery Vial. This product is a request from the field and will be available to Government and Law Enforcement only. Contact us for more information!

We will be sure to let you all know via this site and our email list when these products become available. We're aiming for a mid-2022 launch. In the meantime, they'll need to undergo a TON of testing to ensure they meet the SciK9 standard of excellence of leak-proof containment of canine training aids.
