The Prestige standard

Five checks before a lot is released

Nothing ships on a supplier’s word. Each lot is re-tested in the U.S. and held until every result clears.

01
Identity
Mass spectrometry
Molecular weight confirmed against the expected sequence before anything else runs.
02
Purity
RP-HPLC
Peak area quantified and reported to one decimal; below 99% the lot is rejected.
03
Water content
Karl Fischer
Residual moisture measured to confirm the lyophilization cycle ran to completion.
04
Sterility
USP <71> culture
Fourteen-day culture on every fill lot before release is signed off.
05
Endotoxin
LAL assay
Bacterial endotoxin quantified in EU/mg and printed on the CoA.
Batch record
Released
Lot PBP-2604-A

The paperwork you can cite in a lab notebook.

Every CoA is issued against the lot number printed on your vial: measured purity by RP-HPLC, mass confirmation, water content, sterility and endotoxin results. Chromatograms are archived five years and re-issued on request.

Why buy from us

Built around the way labs actually order

Supply
Stock that holds
High-turn compounds are kept deep enough that an active protocol never waits on a backorder email.
Pricing
Volume without compromise
Multi-vial and standing orders drop the per-vial cost, tested to the same release standard as a single unit.
Shipping
Protected in transit
Rigid, temperature-aware packing with tracking on every parcel, and free reship if a shipment is lost or arrives damaged.
Documentation
Paperwork on demand
Pull the CoA for any lot you have ever received, and request full chromatograms without opening a support ticket.
Testing
Independent verification
Purity and identity confirmed by an ISO 17025 U.S. laboratory before a lot is cleared for release.
Support
Answered by people
Order, documentation and handling questions answered same business day by staff who work with the catalog daily.

What our customers say

4.9 average · 1,240 verified orders
The CoA actually matches the vial lot. That alone put them ahead of the two suppliers we used before.
Research associate · university core lab
Chromatograms on request within a day. Our QA reviewer stopped flagging these orders.
Lab manager · contract research org
Six reorders, six consistent purity results. Packaging survives cross-country transit intact.
Principal investigator · private lab
Ordered Friday morning, on the bench Monday. Cold pack still cold, vials undamaged.
Postdoc · academic research group
Support answered a lot-history question in two hours with the actual chromatogram attached.
Procurement lead · biotech startup
Pricing at volume is genuinely competitive, and the documentation did not get thinner with the discount.
Operations manager · diagnostics lab
We audit every incoming supplier. Prestige was the first in a year to pass without a follow-up request.
QA specialist · CRO
Stock levels on the site are accurate, which sounds small until you have been burned by the alternative.
