01
Reverse-phase HPLC
Purity measured against reference standards for the documented assay result.
Quality System
Documented, Not Claimed
A research material is only as useful as the documentation behind it. Nexora Labs pairs every available lot with independent analytical records and a traceable review path.
01 — The checks
Seven checks on every lot
02
Mass spectrometry
Molecular identity checked by mass-to-charge analysis.
03
Net peptide content
The measured material quantity is documented separately from the label claim.
04
Endotoxin screening
LAL screening is used to assess bacterial endotoxin levels.
05
Appearance & solubility
The lyophilized presentation and reconstitution behavior are reviewed.
06
Heavy metals
Trace elemental contaminants are screened against defined limits.
07
Lot-level archival
Each lot receives a unique identifier tied to its certificate record.
02 — The process
From synthesis to your bench
01
Synthesized to specification
Material is produced to a defined specification and prepared as a sealed lyophilized powder.
02
Independently assayed
A sample is evaluated by a third-party analytical laboratory for purity and identity.
03
Certificate recorded
The COA is connected to the specific lot record before the compound is presented in the catalog.
04
Prepared for research
Materials are sealed and released with documentation available for review.
03 — The record
Every certificate points to a lot
Published COAs identify the compound, lot, analytical methods, assay result, and testing laboratory. Review the available records in the archive, or email sales@nexoralaboratories.com with a documentation request.
