The Flystuff® Ultimate Flypad
The Flystuff® Ultimate Flypad is made of 1/8 in (3 mm) easily replaceable UHMW porous polyethylene paired together with metal casing which helps in reducing static. A precision routed maze along the metal casing assures optimal, consistent diffusion of CO2 throughout the staging area. The Flystuff® Ultimate Flowbed features 3 input options to best suit your setup. The ‘zero-edge’ rim makes it easy and safe for removal of flies.

Conductive Black Surface
You’ll never go back! The black Flypad surface is an exclusive from Genesee Scientific and offers several advantages over the traditional white surfaces of Flypads. The conductive porous material helps to reduce static buildup on the Flypad and reduces glare when viewing flies under a microscope. This black surface provides unmatched contrast so viewing your flies is better than ever.

Flystuff® Flypad
The Flystuff Flypad is made of 1/8in (3mm) UHMW porous polyethylene fused to 3/4in (12mm) 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 1/8in ID (3mm) tubing (substitute fitting for 1/4in (6mm) ID tubing available upon request).


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.

Flystuff® Flowbuddy Flow Regulator

The Flowbuddy Flow Regulator adds convenience and precision flow control to any CO2 Drosophila workstation. The Flowbuddy’s toggle switch is used to instantly start and stop fly work with ease. CO2 flow to the 2 barbed outputs is adjusted with the Flowbuddy’s knurled knob flow regulator which allows effortless, user-determined micro adjustment in LPM (Liters Per Minute) with constant, visible confirmation on the flow meter. Since the Flowbuddy Flow Regulator withstands input pressure up to 100 psi, tank gauges can safely be left open, which eliminates the need to fuss with the tank’s knobs and levers to begin and end fly work. Even when CO2 pressure increases or decreases (i.e. when another workstation on the network is shut off or turned on), the Flowbuddy’s Flow Regulator will maintain a consistent unvarying flow. The Benchtop Flowbuddy Flow Regulator features a sturdy base, non-slip feet, gun hook, and has a small footprint (just 4×6 inches!) to fit nicely on a workstation surface. The Wall-Mount Flowbuddy Flow Regulator is engineered for simple, sturdy installation (hardware included) to free up bench space. The barbed input and outputs are nickel-plated solid brass and fit 1/8 in I.D. (3 mm) tubing.

Flystuff® Foot Pedal

The Flystuff Foot Pedal is a simple and efficient tool designed to conserve CO2 and reduce the risk of over-anesthetizing flies. When compared to a standard continuous-flow setup, the addition of this simple foot valve to your Drosophila workstation can conserve CO2 by 500% or more. This can translate into huge savings. in addition to saving on CO2 cost, the Flystuff Foot Pedal saves he time and tedium involved in having to frequently change out CO2 tanks. The solid brass barbed input and output fit 1/8 in I.D. tubing.
The Flystuff Complete foot pedal system includes: 1 foot pedal; 1 Flypad; 1 Flypad frame; 5 feet 1/8 in I.D. (3 mm) Tubing; 1 “T” Fitting; 1 Blowgun with coiled tube and 0.05 x 1 3/16 in needle (long 0.07 in x 1 3/4 in needle can be substituted free upon request)

Control Static!

We adapted technology from the semiconductor and other electrostatic-sensitive disciplines to your flyroom. Introducing 2 new brushes to help control static electricity using grounded conductivity. It starts with a superconductive specialized bristle fiber filament that is chemically bonded with copper sulfide to produce a corona discharge effect. When this fiber nears the surface of static charged material, it will ionize the air, which acts as a carrier of electrons away from the charged materials.
