THE CLASSIC FOUR-ARM 4-CHOICE ARENA OLFACTOMETER

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 outputs 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.
