Our Standards

What Every Lot Is Tested For

Independent third-party testing is conducted on every lot before it ships. Here's what's verified on every compound we carry.

Identity & Purity

HPLC and mass spectrometry confirm compound identity and purity to ≥99% on every lot. No lot ships without passing this threshold.

≥99% Purity

Microbial Sterility

Two independent sterility labs test each lot for microbial contamination. Dual-lab verification eliminates single-source error.

2× Independent Labs

Bacterial Endotoxins

LAL (Limulus Amebocyte Lysate) testing is performed per lot to detect bacterial endotoxins that can interfere with in-vitro research outcomes.

Per Lot

Elemental Impurities

Heavy metal and trace element screening per ICH Q3D guidelines. Ensures no elemental contamination that could confound analytical results.

ICH Q3D

Lot Consistency

Multi-point analytical verification ensures consistency across vials within a lot and across sequential lots of the same compound.

Full Traceability

Certificate of Analysis

A full lot-specific CoA is generated for every product. Available upon request via email — typically sent within one business day.

Common Questions

Testing FAQ

ISO/IEC 17025:2017 is the international standard for testing and calibration laboratories. Accreditation by an authorized body means the lab's methods, equipment, and personnel have been independently audited and verified to meet a globally recognized quality standard. It's the highest level of third-party lab credentialing available.
CoAs are available upon request rather than included automatically with every shipment. This keeps our packaging clean and our process efficient. Simply email us with your order number and product name and we'll have it to you within one business day — usually much faster.
Yes. If you'd like to review testing documentation before purchasing, email us with the product name and we'll share the most recent lot CoA. We're happy to provide this for any product we carry.
Every lot is tested — not just representative samples. Each new lot of each compound undergoes the full testing panel before it's made available for sale. This includes identity, purity, sterility, endotoxin, and elemental impurity screening.
We work with U.S.-based ISO/IEC 17025:2017-accredited third-party laboratories. We use multiple labs for different testing panels, including dual-lab sterility verification. Specific lab names are available upon request alongside the CoA documentation.
Reach out directly — email team@redhandresearch.com or call (636) 556-GLOW. We're happy to walk through any CoA result with you and answer technical questions about what the data means for your research application.
