Why Caliper
Quality you can check, not just read about
A COA for your lot
Every order ships with the certificate of analysis for the specific lot in the vial — not a generic document.
Independently tested
Purity and identity are measured by an analytical laboratory separate from the manufacturer. We publish the result without editing or summarizing.
Batch-specific COA
Full chromatogram and mass spec trace, tied to the lot number on your vial.
Same-day dispatch
Orders before 2 PM PT ship the same business day from California.

Documented, lot by lot
Every vial traces back to a document you can read
A lot number on the vial and a certificate carrying that same lot number in the box. The analysis is performed by an independent laboratory, and we reproduce it as issued — we do not edit it, summarize it, or put our own name on it.
Check the lot number first. If the number on the certificate doesn't match the number on the vial, the document describes different material. Five seconds, and it is the most useful check you can run on any supplier.

How it works
From synthesis to your bench
Manufactured to specification
Material is produced by our manufacturing partner against an agreed specification for purity and identity.
Assayed and certified
Each lot is assayed by an independent analytical laboratory for HPLC purity and LC-MS identity confirmation, and the certificate is issued in that laboratory's name against that lot number.
Checked on intake
We confirm the certificate matches the lot number on the vials received. Material arriving without a matching, legible certificate is not accepted into inventory.
Documented and shipped
The certificate travels with your order and is filed against the lot number. Discreet packaging, tracked delivery.

Common questions
Before you order
RUO material is supplied strictly for in-vitro laboratory investigation. It is not approved by the FDA for any use, is not manufactured under pharmaceutical GMP, and must never be administered to humans or animals. Our scope is analytical: we supply reference standards to testing laboratories, and our team can help with analytical questions about the material we ship.
An independent analytical laboratory, separate from the facility that makes the material. The certificate is issued in that laboratory's name — not ours — and we reproduce it exactly as issued. Cross-check the lot number on the certificate against the number printed on your vial; if they do not match, the document describes different material.
Transfer lyophilized vials to −20 °C storage, protected from light. Lyophilized peptides are stable at ambient temperature through domestic transit, so refrigerate or freeze promptly after receipt rather than worrying about the shipping window.
Yes. We source and screen custom sequences for institutional clients. Send the sequence, required purity, quantity and timeline and we will return a quote, realistic lead time and the analytical package we can provide.
In-stock orders placed before 2:00 PM PT on a business day ship the same day with tracking. Orders after cutoff ship the next business day.
