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.
reconstituted clean, no cloudiness
handled well in transit
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.
Good vial quality no issues
COA checked out on our HPLC
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.
arrived faster then expected. sealed well
vial seal intact, good
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.
purity matched the coa exactly.
no complaints, tested fine
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.
consistent with the last order
labeling clear and correct
