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.

Downloadable Certificates of Analysis are available from our website. Sold in packs of 10 individually vacuum-sealed microorganism pellets. Stores in the freezer at -20°C to -10°C, with a product shelf life of 18 months from the manufacture date.
