Procurement framework
12 questions before a laboratory order
A low unit price becomes expensive when identity, lot documentation, storage, fulfillment or discrepancy handling cannot be verified.
What is the exact identity?
Record the catalog name, SKU, stated format, quantity and lot number. Avoid nicknames.
Is a batch COA available?
“COA available” is not the same as reviewing the current document tied to the expected lot.
Which claims are documented?
Separate general seller statements from evidence supporting the exact material and batch.
What does RUO exclude?
Purchase records, storage and downstream communication must remain consistent with non-clinical use.
Are storage conditions exact?
Capture temperature, light, humidity, freeze-thaw and stability details where documentation provides them.
Which methods were used?
Match identity, purity or quantity claims to suitable methods and a named testing source where available.
What controls conflicts?
Use verified specifications and batch records—not a headline—as procurement evidence.
What are the shipping terms?
Capture cutoff, method, threshold and destination eligibility at the time of ordering.
What is the refund exposure?
Understand final-sale terms before ordering; they increase the value of pre-purchase verification.
Can discrepancies be resolved?
Document support and escalation paths for damaged shipments, lot mismatches or missing reports.
Is the relationship disclosed?
Affiliate compensation must be obvious and adjacent to the recommendation or tracked link.
