ZeptoMetrix - Analytical Reference Materials Products & Reviews

PT samples have to be right. Your laboratory’s accreditation is at stake, so anything less than 100% confidence is just not good enough. That’s why we bring over 25 years of multidisciplinary reference material manufacturing and certification experience into every step of our process. And that’s why our analytical validation specifications are more stringent than the current TNI standards.

We offer ISO-accredited microbiological certified reference materials. Validated and traceable cultures are no more than two passages from the primary reference culture ensuring genetic traceability to the primary cell line. Each lyophilized culture is preserved in our proprietary Microgel-Flash™ quick dissolve matrix. Pellets dissolve instantly once hydrated. Manufactured and tested under ISO 17034 and 17025 accreditations.

PFAS testing can be highly challenging which is why we make it easier with our convenient portfolio of PFAS reference materials. Advance environmental and health safety with standards you can trust.
