An apparatus for training canines to detect complex hazardous substances from an odor mixture developed from at least two separated material components having at least two separated odors respectively. The training apparatus has a chamber base unit having at least two vial wells configured to hold separate containers of the material components and a chamber top unit having a first side facing the chamber base and a second side opposite the first side. The first side of the chamber top unit and the chamber base unit define a primary vapor mixing chamber in fluid communication with the vial wells. A mechanical seal between the chamber top and the chamber base seals the primary vapor mixing chamber. A passageway extends through the chamber top unit connecting the primary vapor mixing chamber to the second side of the chamber top unit.

An apparatus for generating a mixed vapor comprising first and second vapors from first and second separated material components, the apparatus comprising: a chamber base unit having at least two recesses configured to hold the first and second separated material components;a chamber top unit having a first side facing the chamber base and a second side opposite the first side;the first side of the chamber top unit and the chamber base unit defining a primary vapor mixing chamber in fluid communication with the recesses;a mechanical seal between the chamber top unit and the chamber base unit;the chamber top unit having a passageway extending from the primary vapor mixing chamber to the second side of the chamber top unit, wherein the mixed vapor diffuses from the primary vapor mixing chamber through the passageway to the second side of the chamber top unit; anda flow restrictor provided on the second side of the chamber top unit, wherein the flow restrictor has a cap at a first end, a second end extending into the passageway, and a recessed portion in the second end that maintains a fluid conduit through the flow restrictor and the passageway to the second side of the chamber top unit. 2. The apparatus according to claim 1, wherein the mechanical seal includes an o-ring positioned between opposed sealing surfaces on the chamber top unit and the chamber base unit and radially outward of the primary mixing chamber, and at least one mechanical latch configured to urge the sealing surfaces together and to hold the chamber base unit and the chamber top unit together. 3. The apparatus of claim 1, further comprising: a tube configured to be positioned within the passageway with a first end extending into the primary vapor mixing chamber. 4. The apparatus of claim 3, wherein the tube is cylindrical, and wherein a second end of the tube has a lip adapted to rest on a shoulder within the passageway. 5. The apparatus of claim 3, wherein the second end of the flow restrictor has a diameter configured to fit within the passageway, and wherein the cap has a wider diameter that extends radially outward past the circular upper edge of the passageway. 6. The apparatus of claim 3, wherein the flow restrictor comprises a plurality of fluid conduits that extend from the second end to the cap, and wherein a gap is formed between the cap and the second side of the chamber top unit, such that vapor can diffuse from the mixing chamber through the tube, through the fluid conduits, and through the gap to the second side of the chamber top. 7. The apparatus according to claim 1, wherein a recess in the second side of the chamber top unit forms a secondary vapor mixing chamber in fluid communication with the passageway and the primary vapor mixing chamber. 8. The apparatus according to claim 7, further comprising: a lid configured to cover the recess in the second side of the chamber top unit. 9. The apparatus according to claim 8, further comprising: at least one magnetic catch for removably holding the lid over the recess. 10. The apparatus according to claim 7, further comprising: an air inlet at an outside surface of the chamber base unit providing air flow from outside the apparatus into the primary vapor mixing chamber; andan air outlet at an outside surface of the chamber top unit providing air flow out of the secondary vapor mixing chamber. 11. The apparatus according to claim 1, further comprising: a water jacket in at least one of the base unit and the top unit configured to heat or cool the apparatus with warmer or cooler water. 12. An apparatus for training canines to detect a mixed vapor comprising first and second vapors from first and second separated material components, the apparatus comprising: a chamber base unit having at least two recesses configured to hold the first and second separated material components;a chamber top unit having a first side facing the chamber base and a second side opposite the first side;the first side of the chamber top unit and the chamber base unit defining a primary vapor mixing chamber in fluid communication with the recesses;the chamber top unit having a passageway extending from the primary vapor mixing chamber to the second side of the chamber top unit, wherein the mixed vapor diffuses from the primary vapor mixing chamber through the passageway to the second side of the chamber top unit;a tube configured to be positioned within the passageway with a first end extending into the primary vapor mixing chamber; anda flow restrictor having a first end with a cap having a diameter that extends radially outward beyond an outer diameter of the passageway, the flow restrictor having a second end with a diameter configured to fit within an inner diameter of the passageway, where the second end comprises a recessed portion that maintains a fluid conduit through the flow restrictor and the passageway, and where the second end of the flow restrictor is configured to form a gap between the cap of the flow restrictor and the passageway. 13. The apparatus of claim 12, further comprising: an air inlet at an outside surface of the chamber base unit providing air flow from outside the apparatus into the primary vapor mixing chamber; andan air outlet at an outside surface of the chamber top unit providing air flow out of a secondary vapor mixing chamber formed by a recess in the second side of the chamber top unit. 14. The apparatus according to claim 12, further comprising: a water jacket in at least one of the base unit and the top unit configured to heat or cool the apparatus with warmer or cooler water. 15. The apparatus of claim 12, wherein the tube is cylindrical, and wherein a second end of the tube has a lip adapted to rest on a shoulder within the passageway. 16. The apparatus of claim 12, wherein the flow restrictor comprises a plurality of fluid conduits that extend from the second end to the cap, such that vapor can diffuse from the primary vapor mixing chamber through the hollow tube, through the fluid conduits, and through the gap to the second side of the chamber top. 17. The apparatus of claim 12, wherein the second end of the flow restrictor has a friction fitting with the passageway. 18. An apparatus for generating an odor mixture developed from at least two separated material components, the apparatus comprising: a chamber base unit having at least two vial wells configured to hold the separated material components;a chamber top unit having a first side facing the chamber base and a second side opposite the first side;the first side of the chamber top unit and the chamber base unit defining a primary vapor mixing chamber in fluid communication with the vial wells;the chamber top unit having a passageway extending from the primary vapor mixing chamber to the second side of the chamber top unit and allowing vapors to diffuse from the vial wells to the second side of the chamber top;a tube configured to be positioned within the passageway with a first end extending into the primary vapor mixing chamber; anda flow restrictor having a first end with a diameter configured to fit within the passageway, and having a cap with a wider diameter at a second opposite end that extends radially outward past the circular upper edge of the passageway,wherein the flow restrictor forms a plurality of flow conduits that extend from the first end to the cap, and wherein a gap is formed between the cap and the chamber top unit, such that vapor can diffuse from the mixing chamber through the tube, through the flow conduits, and through the gap to the second side of the chamber top. 19.
