Read more off the label: part number, MW, NFPA diamond, SDS instructions

A bottle scan now also picks up a manufacturer's part number (PN/P-N), the molecular weight printed on the label, an NFPA 704 fire diamond, and any instructions for finding the safety data sheet. Sigma-Aldrich's own "PCode" and "Source" codes are now recognized as the order number and lot number. Re-scan an existing bottle to pick these up.
