to be used as reference material for authentication and titration of botanicals or plant based products.

qRE are hydro-alcoholic extracts of plants grown in ISV's own botanical gardens, ensuring full identity and traceability.

qRE are delivered in powder form, as 100mg samples in an amber borosilicate vial, with a Certificate of Analysis identifying and quantifying the molecular composition of the reference extract, a Technical Documentation specifying the HPLC and HPTLC methods used, and a Safety Data Sheet.
