Open a lot record
A lot that has not been released has no record to open. That is the answer, not an error.
How it works
Three steps, no account
Nothing here is gated. There is no login between a lot number and its record.
Find the identifier
It is printed on the vial label and repeated on the top panel of the carton, so a vial separated from its box can still be traced.
Open the record
Type it into the field above. The lookup resolves the identifier against the released lots on this site and nothing else.
Read it as written
Result, unit, method, method version, laboratory, scope and dates. Where a test was not run, the record says so in words.
What a record carries
The measurement
The result with its unit and detection limit, and the method and method version that produced it. A figure with no method attached is not published at all.
The laboratory
The name of the independent laboratory that performed the work and the scope of its accreditation. Naming it is what makes the result checkable by somebody who is not us.
The dates
When the sample was received and when it was tested. A purity figure describes the sample submitted on the stated date, not the vial forever.
The state
One of six, written in words: no lot released, held pending test, current, historical, superseded, or rejected before sale. Superseded and rejected lots keep their addresses rather than disappearing.
Records
Published in full when a lot is released
Records appear at the lot lookup as lots are released.
