The Evidence

Don't Take Our
Word For It.

Blackwell BioLabs supplies laboratory research materials with product information and batch documentation. Our COA reports include endotoxin, microbial sterility and heavy metal screening. Read the report for your product and batch to see its listed tests, results and limits.

Start with the specific material, its label and the documentation available for its batch.

The Blackwell standard

Made here. Documented by batch.

100% in-house USA manufacturing, ISO 9001-certified quality management, HPLC verification and batch-specific Certificates of Analysis (COAs).

ISO 9001 concerns quality management. CE marking is a separate conformity mark for products covered by applicable EU requirements; refer to the specific item documentation. Neither replaces a batch analytical report.

The Testing Method

What Is HPLC Testing?
Why It Matters.

HPLC (High-Performance Liquid Chromatography) is an analytical method that separates the components of a sample by passing it through a column under high pressure, then measures detector response at each component. For peptides, HPLC quantifies purity by measuring the peak area of the target compound relative to all detected material. It is the industry standard for research-grade peptide quality verification.

Self-reported purity

Ask what method, sample and report support the stated result.

In-house testing

Still a conflict of interest. The lab is owned by the seller. Results are not independently verified.

Third-party HPLC

Check the issuer, analytical method, sample reference and reported result. Independence is one consideration when assessing a report.

The Document

How to Read a Peptide
Certificate of Analysis

A Certificate of Analysis (COA) is a document from an analytical laboratory reporting the results of testing on a specific production batch. A valid COA comes from an independent third-party lab, not the supplier, and is batch-specific rather than generic to a product line.

1

Identify the Issuing Laboratory

The lab name should appear at the top of the document. It must be an independent third-party analytical laboratory, not the supplier itself. If the issuer is the same company selling you the product, the document is not independent verification.

2

Check the HPLC Purity Percentage

Look for the purity figure from HPLC analysis, expressed as a percentage. Interpret the result using the stated analytical method and its limitations. This must be specific to this batch, not a generic product claim.

3

Note the Batch or Lot Number

The COA is only valid for the specific production run it was issued for. Find the batch or lot number on the document, then cross-reference it with the number printed on your product vial or packaging.

4

Confirm the Test Date

Review the sampling and testing dates together with the batch reference and product storage information. Ask the supplier to clarify missing dates.

The Stakes

Why the Source of Testing Matters

The Problem With Self-Reported Purity

A number without a sample reference, analytical method or report is difficult to assess. Ask for the documentation supporting a material specification.

Assess the Report and Its Scope

Identify the laboratory that issued the report and review its methods, sample reference and stated limitations. A third-party report still applies only to its tested sample and scope.

What We Actually Do

Available reports can be opened from our certificate library. Check that a document matches the material and batch you are considering. Contact us if that connection is unclear.
