Industrial Surfaces Biofilm Reactor
Biofilm Reactor for Intermittently Wetted and Humid Surface Research
The Industrial Surfaces Biofilm Reactor (ISBR) is a bench-top biofilm growth chamber designed for studying biofilm under low shear, high gas transfer, and intermittent wetting conditions. It is the appropriate reactor when the research environment involves surfaces that are periodically wetted rather than continuously submerged, including industrial cooling towers, food preparation surfaces, painted and coated surfaces, and marine environments.
The reactor holds 18 slide coupons (0.6″ x 3.0″) mounted vertically in a rotating polycarbonate coupon holder disc inside a multi-ported glass vessel with a working volume of approximately 275-300 mL. A magnetic stir plate rotates the coupon holder disc under a drip or spray influent port in the ported lid, intermittently wetting each coupon as it passes beneath the nutrient stream. The nutrient stream gravity-flows into a sump at the base of the vessel, where it can be recycled back through the system or drained to waste. All reactor components are autoclavable and reusable.

Includes multi-ported glass vessel, ported lid, lid seal assembly, coupon holder rotor, fluid distribution port, 18 coupons (various materials available), and magnetic stir/hot plate.
Adjustable Coupon Angle
The coupon holder disc supports three adjustable coupon mounting angles: 80, 90, or 100 degrees from horizontal, allowing the nutrient stream to preferentially contact the front face, rear face, or both faces of each slide coupon. This adjustability makes it straightforward to model different wetting geometries without changing the reactor setup. The reactor ships with coupons set at approximately 90 degrees.
Applications
The ISBR is designed for research environments where surfaces are intermittently wetted or exposed to humid conditions rather than continuously submerged. Primary applications include industrial cooling tower biofilm studies, food preparation and food contact surface testing, painted and coated surface evaluation, and marine biofouling research. The reactor is also used for public health biofilm studies on surfaces subject to periodic wetting such as bathroom fixtures, HVAC components, and building materials. The combination of low shear, high gas transfer, and controlled wetting frequency makes the ISBR suitable for growing both wet and dry-phase biofilms on the same coupon surface within a single experiment.
