What the lab found.
The three numbers on the certificate.
Measured by Eurofins Food Testing UK Ltd. Certificate AR-25-UD-075543-01.
01 Β· Why we pay for this
We pay for the test. The lab has no stake in the result.
Most sellers in this category publish nothing. No certificate, no reference number, no lab named. The cost of testing per batch is one reason. A document that can be checked is the other.
Eurofins is UKAS accredited to ISO 17025. That is a fact about the laboratory: its methods and competence have been assessed by an independent accreditation body. It is not a statement about our product.
What the test tells you is what was in the sample they received, measured by stated methods, against stated limits. Heavy metals came back within UK safe limits.
What it does not tell you is anything about effects. A contaminant test measures contaminants. We publish it so you can check the material, not so we can imply anything else.

Food-grade stainless Β· filtration02 Β· How to read it
Three things to check before you believe anyone.
Including us. These are the parts of any certificate of analysis worth looking at.
AR-25-UD-075543-01. A certificate without a reference is not a certificate. This is the string you quote back to the lab or to us.
Eurofins, named on the document, UKAS accredited to ISO 17025. Check the lab exists and that the accreditation is real before you read anything else.
Each row is one parameter, with the result, the limit it was assessed against and the method used. Anything not in the table was not tested.
What is Eurofins?
An independent testing laboratory group. The UK laboratory that tested our resin is UKAS accredited to ISO 17025, which means an independent body has assessed its methods and technical competence.
Who paid for the test?
We did. That is worth stating plainly, because it is the obvious objection. The lab is paid to run stated methods and report what they find; it has no stake in the outcome and no commercial relationship with us beyond the invoice.
What does "within UK safe limits" mean?
It means the heavy metal results fell inside the maximum levels applied in the UK for this kind of product. It does not mean none were detected, and we will not phrase it that way.
Does this test prove the product works?
No. It is a contaminant and identity test. It says what was in the sample and what was not. It says nothing at all about effects, and any seller who presents a purity certificate as proof of benefit is misreading their own document.
Can I see the raw report?
Yes. The certificate is published in full on this page and downloadable as a PDF. Not a summary, not a quote from it. The document.
