Send in your product

If your product requires a challenge test, send it over to us. In its final packaging or a different one - as long as it’s at least 200 ml.


Let’s test!

We send the product to the microbial lab. The lab initiates the test. We share weekly scores with you.



After a week or 5 we’ll receive the end result. Positive? This means testing is over. Didn’t make it? We’ll help you take care of this, directly.
