The FlyStuff Flypad is the highest quality carbon dioxide flow bed available for Drosophila research and is the perfect accessory for your fly work station. This CO2 apparatus is made of 1/8" UHMW porous polyethelene plastic fused to a 3/4" acrylic base. The large sized Flypad provides an additional ~45cm3 of surface area compared to the standard Flypad for even more convenience and ease. A precision routed maze runs through the base and 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" ID (3mm) tubing (This can be substituted for a that fits 1/4" (6mm) ID tubing upon request).
