Our Quality
Commitment
Rigorous batch controls, independent analytical testing, and clearly documented release requirements guide every product we offer.
The Landmark Difference
Our U.S.-based operation applies strict testing, documentation, and batch-release requirements before a lot is made available.
USA-Based Operations
Landmark Biotech is headquartered and operated entirely in the United States. Batch review, warehousing, quality documentation, customer support, and fulfillment are managed domestically.
Controlled Release
Every lot must complete our testing and documentation review before it is approved for research purchase.
Third-Party Tested
Each offered batch is submitted to an independent laboratory for analytical testing. Available Certificates of Analysis are published by lot for direct review.
Results-Based Review
Release decisions are based on the reported analytical results for the finished product. Lots that do not meet our acceptance criteria are not offered for sale.
Our Quality Process
A documented six-step workflow governs how each batch moves from registration through testing, review, and release.
Batch Registration
Each lot is assigned and recorded as a distinct batch so its testing, documentation, inventory, and release status remain clearly associated.
Sample Submission
A batch-specific sample is submitted for independent analytical testing. Results from one lot are never treated as evidence for another.
Independent Testing
Finished-product samples are submitted to an independent analytical laboratory for applicable identity, purity, and content testing.
Results Review
We review the laboratory report against our acceptance criteria before making the associated lot available for purchase.
Documentation
Test reports are associated with the corresponding lot, and available Certificates of Analysis are published so researchers can inspect the reported results.
U.S. Warehousing & Fulfillment
Released inventory is warehoused in the United States and fulfilled with lot identification preserved through shipment.
Our Commitments to You
Independent Verification
We do not rely on presentation alone. Finished products are evaluated through independent analytical testing before release.
Batch Traceability
Every vial can be traced back to its production batch with full documentation and third-party test results on file.
Lot-Level Decisions
Test results apply to the specific lot sampled. Each new lot is reviewed on its own documentation and reported analytical results.
Transparent Communication
We publish available lot-specific test documentation and welcome questions about our quality controls, release requirements, and testing methodology.
Quality you can verify
Review the available lot-specific Certificates of Analysis before purchasing. Product documentation is accessible from the catalog and product pages.
