Clean air delivery system (CADS:CADS-4CPP)

The Clean Air Delivery System for 4-Choice Arena Olfactometers is a 4 push to 1 pull (vacuum) system. This system is designed to be used with a 4-Choice Arena Olfactometer and may also be used as a “CADS” for two Y-Tubes or any other 2-choice, 3-choice or 4-choice olfactometer. The vacuum flow meter may also be used as a pull system for volatile collection apparatus. CADS-4CPP includes 4 X 2.3 LPM clean air source flow meters and one 0-6 LPM vacuum flow meter. The two sets of four holes in the center are for an upgrade to a variable humidity system, two vacuum flow meters allows for three asymmetrical volatile collection, or two positive pressure flow meters for six choice olfactometers.

4-choice olfactometer (Olfactometer-Arena:4-Choice Olfactometer KSB)

The classic 4-Choice Arena Olfactometer (4-COA) is a 12" x 12" x 1", 5-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. 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, 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.

True choice adaptor (Olfactometer-Arena:True Choice Arena Add-on)

Insect Introduction port with Clean Air flowing over the back of the insects. This air flow allows the “True” separation of the odor source and the clean air control. The True Choice Olfactometer™ will allow for conclusive tests of repellents as well as attractants.

Classic y-tube (YT 1922, 2425); Specimen adaptor (SA 1922, 2425); Inline odor source (IOS 1922, 2425); External odor source (OSE 1922, 2425)

Y-Tube Classic Style setup with one Inline Odor Source (OSI), one ¼” tube adaptor External Odor Source (OSE), one Specimen adaptor at the foot of the Y-Tube. All adaptors are locked in place with joint clips.

Guillotine (CHAMBER:Guillotine 14)

Adjustable Height Guillotine stand for up to 12-inch (318 mm) Chambers. Stand is rigidly made to support the largest chambers. The guillotine top is made from 1.5” HDPE with cut groves for locking in place.

Lock in design allows for easy plant placement. Comes with 25” X 2” X ¼” activated carbon strip to seal off the plant stock (about 4 to 6” of strip used for each plant exchange.) Each table comes with one cut grove ring for chamber size.

Dome chamber (CHAMBER:Chamber Solid Dome 10X21)

One Piece borosilicate glass dome 12.5” (318mm) OD by 18” (457mm) internal height. A glass thread for ¼” tubing is fused into the top of the dome for push or pull air flow to the guillotine port. The top center is less likely to be broken during cleaning. 12” IO-Rings and 12” glass sections may be used to increase the height of the chamber.

Chamber body (CHAMBER:Chamber 10 Glass/IO-Ring Add-On)

First sectional set for the 10” Sectional Volatile Collection Chamber. Solid borosilicate glass dome 10” OD; 10X15” heavy wall glass center section; and a 10” IO-Ring with a single port that is vacuum heat treated for removal of all volatiles. An additional 11 ports can be added for a total of 12 ports (see Chamber IO-Ring Port.) This designed can be used for hourly volatile collection with a timed 6, 8, or 12 port vacuum unit.

Smoke Emitter Unit

The Sigma Scientific Smoke Emitter Unit is the perfect tool to adjust your olfactometer for laminar flow. The main smoke adaptor fits the 4-Choice Arena Olfactometers and 24/25 Y-Tubes, has a glass thread for air flow input and an angled smoke pencil holder. The patented (1) smoke-emitting wick that makes this possible is inserted into the clutch pencil and ignited. The smoke pencil is then inserted into the glass smoke adaptor, such that the o-ring creates an air tight seal. You can adjust the wick to provide a continuous stream of a light gray to white smoke. The Smoke Pencil can be easily extinguished by simply replacing the protective cover. Wick diameter is 5.6mm and will burn for approximately 30 minutes each. This cool burning, non-toxic emitter is ideal for air stream balancing to achieve laminar flow in your Olfactometer.
