CDC Biofilm Reactor®


Unlock the Potential of the CDC Biofilm Reactor® for Your Research and Development Needs

Explore the versatile capabilities of the CDC Biofilm Reactor® for a wide range of applications, including product development related to anti-microbial testing, anti-microbial surfaces, and coatings testing, industrial systems corrosion testing, food processing equipment sterilization testing, and medical device testing. Our cutting-edge system is designed to streamline your research processes, making it the ideal choice for scientists, engineers, and academic researchers.


Precise and Efficient Design

The CDC Biofilm Reactor® features eight polypropylene coupon holder rods suspended from a UHMW-polyethylene ported lid. Each holder rod can accommodate three 1/2-inch (12.7 mm) diameter coupons. These components are assembled within a 1-liter glass vessel, complete with a side-arm discharge port. Liquid growth media, biocides, and more can be efficiently circulated through the vessel, with mixing and shear generated by a magnetic stir bar/vane rotated by a magnetic stir plate.


Experience the difference and accelerate your path to innovation and discovery with the CDC Biofilm Reactor®.
