“…it’s made working with anaerobes a lot easier”
“Reliable and easy to use. Pre-reduced is an added benefit”
OxyPRAS Plus® Plates vs. Other Plates
To isolate and grow anaerobes the literature teaches that you need:
- An anaerobic environment
- Chemically reduced media
- A medium prepared for anaerobes which is Pre-Reduced Anaerobically Sterilized
Here is how the OxyPRAS Plus® Plates stack up to the competition. Click here to download a pdf summary outlining the full features, advantages and benefits of OxyPRAS Plus® Plates when compared to Other Plates.
