Lexar Montreal keeps a short catalogue on purpose. Two characterized compounds, the standards that calibrate them, and the consumables that keep a shipment intact.

Every lot is separated by reverse-phase HPLC, matched against a reference standard, and released only once an independent laboratory has signed the certificate. Nothing leaves the cabinet on a shipping deadline.

The store is the same operation, opened to order directly. Same lot numbers, same paperwork, same cold room.
