What are CADS in this context?
They are clean air delivery systems designed to provide contaminant-free air flows in experiments involving insects and other organisms in an arena olfactometer.
insects are exposed to different odor sources to study their behavior. CADS ensure that:
✅ The air supplied is clean and free of impurities that could alter the results of the experiment.
✅ The air flow is constant and controlled, avoiding variations that could influence the response of the insects.
✅ Odors are accurately transported from source to test system without unwanted contamination.
The classic 4-Choice Arena Olfactometer, as shown in Figure A (4-COA) is a 12" x 12" x 1", 4-Port Arena Olfactometer w/removable lid. The main body and all inlet & outlet ports are made from solid UHMW-Poly Ethylene (PE) with a 1/4" thick clear Plexiglas removable Lid.
System includes a bottom fed insect inlet adapter made of borosilicate glass with glass frit to stop insects from moving into the vacuum system.
NOTE: Specify insect size at time of order.) 4-COA includes four sets of borosilicate glass 2-piece combination ¼” Teflon™ tube adapter and Insect Isolation Traps (IIT) which collect insects responding to an odor source and prevents them from returning into the arena or reaching the odor source.
We include 2 Inline Odor Source Chambers (Figure B), 24/40 with stainless steel screen fused into the glass with UHMW double o-ring end cap to ¼” tube adaptor. Unit also includes a 2-CHOICE ADAPTER insert which allows the olfactometer to be converted to a two choice system by blocking off half of the arena area. Olfactometer is supported by (4) - 6" removable legs.
To operate the system a 4 push with 1 pull Clean Air Delivery system is needed. Figure C is a diagram which shows a complete system with both a 4-Choice Arena Olfactometer hooked up to our Clean Air Delivery System, CADS-4CPP which is sold separately.
The CADS-4Push-1Pull has 4 filtered air otputs and 1 vacuum input for air flow control. The 4 push flow meters produce 0-1.3 LPM of clean air and the vacuum side has a 0-6 LPM vacuum flow-meter to be connected to bottom insect trap on 4-Choice Olfactometer, installed in single lighted and lockable chest. System requires compressed air source at 50-100 PSI pressure.
Port A1 is using an External Odor Source like a potted plant in a sealed Multi-Use Chamber. Also guillotines stand with our Multi-Use Chamber Dome and the ¼” tube adaptor for use with just the top of a plant.
Port A2 and A3 are using our Inline Odor Source Chambers for the use of small odor source such as SPME or insects.
Port A4 is a direct connection to the Clean Air Delivery System (CADS) providing a control port or ports of clean non-odor air into the choice schematic.
