Verified Potency: Every Single Vial
High-Performance Liquid Chromatography (HPLC) confirms that every material meets its labeled concentration. We reject any batch that falls below 99% potency before it ever reaches you.
HPLC Verified Labeled Concentration Confirmed 3rd Party Lab
Average Potency Across Catalog99.4%
Batches Passing First Test97.8%
Molecular Identity: Confirmed by Mass Spectrometry
LC-MS (Liquid Chromatography–Mass Spectrometry) verifies the exact molecular structure of every material. This eliminates counterfeits and confirms you're receiving exactly what the label says.
LC-MS Verified Molecular Identity Confirmed Zero Substitutions
Purity (Chromatographic)>99%
Molecular Match Accuracy100%
Long-Term Stability: Lyophilized Form
All reference materials are supplied in lyophilized (freeze-dried) powder form, a format selected for analytical stability and long-term storage of the material under laboratory conditions.
Lyophilized Form 24-Month Shelf Life Cold-Chain Shipped
Potency Retained at 12 Months (−20°C)>98%
Endotoxin & Microbial Safety Testing
Every lot undergoes Limulus Amebocyte Lysate (LAL) testing for bacterial endotoxins and microbial contamination screening, documenting suitability for in-vitro laboratory research environments.
LAL Endotoxin Test Microbial Screen Research Grade
Heavy Metal & Solvent Residue Testing
ICP-MS testing screens for trace heavy metals (lead, arsenic, mercury, cadmium) and residual solvent analysis confirms that synthesis solvents are removed to below detection limits, ensuring research-grade cleanliness.
