ReadyNow™ Biofilm Test Carriers

        ReadyNow™ Biofilm Test Carriers by Stratix Labs™ are a simple way to conduct anti-biofilm testing. These are pre-grown, ready-to-use biofilm carriers for disinfectant efficacy testing using Pseudomonas aeruginosa or Staphylococcus aureus. The carriers are stable at 4°C for more than twelve (12) months. Twenty-four (24) biofilm test carriers are included in each kit, resembling a full CDC Biofilm Reactor® sample run.

       These test carriers are available through BioSurface Technologies Corporation as a preliminary tool to help assess your liquid disinfectant formulations before launching full biofilm reactor studies using one of our many reactors currently available.

ReadyNow™ Biofilm Test Carriers (Pack of 24)

ReadyNow™ Biofilm Test Carriers Packaging

Reducing prep work and setting a new level of standardization.

Pre-grown, preserved biofilms with the requisite cell counts for the EPA MB-20 and ASTM 2871 Single Tube Method. With ReadyNow™, you eliminate the need to spend valuable time preparing test samples, and eliminate the uncertainty associated with consistently hitting your cell count targets.

All ReadyNow™ Biofilm Test Carriers are manufactured using authentic, high quality ATCC® microorganisms. They can be conveniently stored between 2ºC to 8ºC for more than a year and comes with a Certificate of Analysis detailing the mean colony forming units for each batch produced – improving your ability to standardize your testing.

ReadyNow™ Biofilm Test Carriers are not currently approved by ASTM or the EPA for product validation and should be used as a tool for preliminary testing only.

ReadyNow™ Biofilm Test Carriers are the easiest way to conduct preliminary anti-biofilm testing.


  • Can be utilized to evaluate biofilm kill or biofilm removal efficacy of disinfectants

  • Recoverable cell counts can be assayed with CFU enumeration or using stains (e.g., crystal violet stain)

  • Eliminates uncertainty associated with producing inoculated carriers in-spec; each product comes with a Certificate of Analysis detailing mean CFU count for that batch

  • Simply rehydrate for 20 minutes and you’re ready to conduct your assay

  • Stable for >1 year from manufacture date when stored between 2°C to 8°C
