EnglishHow to Request a Certificate of Analysis (COA) from Capitol Scientific
Updated
Capitol Scientific provides a Request COA entry point on its website for customers who need a Certificate of Analysis, typically to confirm the quality and specifications of a chemical lot. You can also use the Procurement Portals link if your institution routes purchases through a procurement system, or call customer assistance at 512.836.1167 if you need help locating the right document. The site does not state a turnaround time or whether a login is required for the COA request itself, so treat those as things to confirm when you submit the request.
What a COA Is and Why You Need It
A Certificate of Analysis is a document issued for a specific lot or batch of a chemical or reagent. It records the specifications tested and the results for that batch, which is why it is tied to a lot number rather than to a product page alone.
Typical uses:
- Confirming a reagent meets the grade or purity your protocol requires
- Documenting incoming material for a lab’s quality records
- Matching a received bottle to the batch documentation supplied by the manufacturer
Because the certificate is lot-specific, the more identifying information you can supply, the faster the request can be matched.
How to Submit a COA Request
- Go to capitolscientific.com and locate the Request COA link in the site’s utility/navigation area (it appears alongside Login | Register, Store Locator, Procurement Portals, and Quick Order).
- Provide the product and lot identification for the material you received — the catalog number and the lot number printed on the container label are the key inputs.
- Submit the request and wait for the document to be returned or for a representative to follow up.
- If you do not have the lot number, or the request does not resolve, call 512.836.1167 for assistance.
Expected result: you receive the analysis documentation for the specific batch in question, which you can then file with your receiving or quality records.
Information to Have Ready
| Item | Where to find it | Why it matters |
|---|---|---|
| Catalog / product number | Product page or container label | Identifies the exact item |
| Lot or batch number | Container label | COAs are lot-specific |
| Order or invoice number | Your purchasing records | Helps match the request to your transaction |
| Quantity and date received | Packing slip | Useful if the lot is ambiguous |
If You Buy Through a Procurement System
Capitol Scientific lists Procurement Portals as a site entry point. If your organization places orders through a procurement platform, that route is the one intended for institutional purchasing workflows. For document requests tied to those orders, the same catalog and lot details apply, and customer assistance at 512.836.1167 is the fallback when the portal does not surface the document you need.
Common Snags
- No lot number. Without it, the request may need to be traced through your order history. Have your order number ready before calling.
- JavaScript disabled. The site notes that JavaScript must be enabled (or the browser upgraded) to view the site, so the Request COA link may not function if scripts are blocked.
- Discontinued items. Some manufacturer lines are flagged as discontinued (for example, the PRO Scientific discontinued items listing). For these, confirm with a representative whether batch documentation is still obtainable.
- Assuming instant delivery. The site does not publish a response time for COA requests; plan for a follow-up rather than same-minute delivery.
When to Call Instead
Reach 512.836.1167 if you cannot find the Request COA link, do not have the lot number, need documentation for a discontinued product, or need the certificate routed to a specific quality or procurement contact. A representative can also help you plan ahead if your supply is running low, which is useful when a COA is needed for a reorder of the same material.
