"The FlyStuff Flypad is made of 1/8"" UHMW porous polyethylene fused to 3/4"" acrylic base.
The precision routed maze maintains a flat, warp-free surface and also assures optimal, consistent diffusion of CO2 throughout the staging area. The FlyStuff Flypad features a nickel-plated brass threaded hose barb input that fits 1/8"" I.D. tubing (substitute fitting for 1/4"" I.D. tubing available upon request). Footprint: 8.1cm x 11.6cm (about the size of a standard pipet tip tray). Compatible with the Fly Condo."
"The FlyStuff Flypad Frame is a white acrylic frame with a precision routed recessed groove that
fits precisely on top of the FlyStuff Flypad. The fit allows for easy one-handed removal, and the recessed gravity fit keeps the frame securely in place when in use. The benefit of this frame is two fold: 1) CO2, being heavier than air, is more efficiently contained within the frame. This is especially beneficial when the FlyStuff Foot Valve is used. 2) The frame adds protective walls to the flypad surface to best contain flies and assure that they will not inadvertently be swept off the flypad."
