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 of it 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 and a gun hook. It also has a small footprint (just 4x6 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 1/8in. I.D. tubing.
