batch number matched the certificate

purity matched the coa exactly.

ordered for a comparative assay and it dissolved cleanly in bac water, no visible particulates. HPLC trace lined up with the posted COA within tolerance. packaging was adequate and the batch label matched. would use again for this workflow.

packaging was discreet 👍

consistent with the last order

honestly wasnt expecting much but the documentation was thorough — coa, hplc and mass spec all linked and the batch numbers matched what shipped. purity read high on our end. only note is the box was a little dented but the vials were fine inside.

reconstituted clean, no cloudiness

handled well in transit

Third order from them now. consistency between lots has been good which matters for our reference standards. delivery to the university took a few days but tracking was accurate the whole way. vials well sealed, no leakage.

Good vial quality no issues

COA checked out on our HPLC

received quickly, reconstitution was straightforward and stayed in solution. we cross-checked against the certificate and identity confirmed. support answered a batch question within a day. discreet packaging which we appreciate for the dept mailroom.

arrived faster then expected. sealed well

vial seal intact, good

the lot we got tested within spec on our instrument, purity slightly above the stated value actually. appreciated that every product links its own coa/hplc/ms — makes record keeping easier. shipping was tracked and fast. minor: label font is small but readable.

no complaints, tested fine
