Certificates on this page are third-party analytical reports supplied with the research materials we stock. Progressive Bioscience reviews this documentation against the product identity, specification and material received before inventory is released for sale. Reports are published where applicable. For questions about the documentation for your order, email contact@progressivebioscience.com with your order number.

Reading these results

  • Identity (LC-MS) confirms the material’s molecular mass matches SS-31.
  • Net content is the measured amount in the vial compared with the label amount.
  • Purity (HPLC) is the main peak as a percentage of all detected material. Both batches exceed the 98% specification.

Verifying a certificate

Kovera Labs certificates list a report number and access code with a QR code for the lab’s verification page, and SteriGenix certificates carry a report number. Compare the report number, batch and results on the lab’s site with the certificate.
