Product and lot
Choose one compound, strength and intended lot for a focused trial. Confirm sample availability and request its COA before payment. Sample order process →
SeqLine Bio · Trial order
Trial first · B2B research procurement
Trial one kit before you scale.
Set acceptance criteria before payment. Most catalog compounds start at 1 kit: 10 vials of one compound and strength. Confirmed stock: within 3 business days after written payment confirmation; samples requiring preparation: 3–7 business days after specification and payment confirmation. Stock and the dispatch date are confirmed before payment. Review material, documents and delivery before scaling. Made-to-order products start at 100 kits.
Plan the trial
Agree what you will accept before ordering.
Tests and limits
If independent testing is needed, choose a laboratory and agree methods and acceptance limits in advance. HPLC purity and MS molecular-weight evidence answer different questions. Arrange testing →
Delivery and remedy
Confirm the contracting entity, payee, dispatch window, destination documents and written quality-claim terms. Verify the order →
Acceptance sheet
Record evidence for each decision.
| Check | Evidence to retain | Acceptance condition |
|---|---|---|
| Product and lot | Quotation, COA, public lot record and photographs of labels. | Compound, strength and lot match across the confirmed order, COA and received labels. |
| Identity evidence | COA MS result; independent report if agreed. | Molecular-weight result is consistent with the expected compound under the agreed method. MS alone does not establish full structural identity. |
| Purity | COA HPLC result; independent report if agreed. | Meets the agreed limit under the agreed method. Published release specification: NLT 98.0% by HPLC. |
| Seller and payee | Quotation, PI and payment instructions. | Seller and payee details are consistent, or a different payee is explained and authorized in writing before payment. |
| Packaging and documents | Arrival photos, seals, labels and destination paperwork. | Condition and documents meet the agreed order requirements; record any damage or missing items. |
| Dispatch | Order confirmation and dispatch/tracking record. | Dispatch falls within the quoted window. Assess transit and arrival condition separately. |
| Additional tests | Independent laboratory reports where required. | Any agreed net-content, sterility, endotoxin, stability or other requirements are assessed separately; HPLC/MS do not establish these results. |
Record each item as accepted, unresolved or failed. Keep the quotation, lot documents and test reports together. Read COA, HPLC and MS results →
After the review
Choose the next step from the evidence.
Accepted · request a larger quote
If agreed checks pass, request pricing at 10, 100 or 1,000 kits, or discuss raw powder by amount. Confirm the new lot, lot split, documents and schedule. Compare quantities →
Unresolved · clarify first
If a result, document or packaging detail is missing or unclear, keep the trial open. Ask for clarification or the agreed additional testing before placing a larger order.
Failed · resolve the issue
Pause scale-up, retain material and packaging, record the issue and follow the written claim process. Confirmed quality issues are replaced or refunded under the quality policy.
A successful trial applies to that lot and order. Every new lot needs its own COA and acceptance review. Private label starts at 100 kits (1,000 vials); approve the material before committing to packaging. See the private-label workflow →
FAQ
Questions before you order.
How small can a trial order be?
1 kit (10 vials of one compound and strength) for most catalog compounds. Made-to-order products start at 100 kits (1,000 vials); confirm eligibility before planning a one-kit trial.
When does a sample ship?
Confirmed stock: within 3 business days after written payment confirmation; samples requiring preparation: 3–7 business days after specification and payment confirmation. Stock and the dispatch date are confirmed before payment. Transit and customs processing take additional time; confirm destination-specific delivery terms, including DDP where eligible, in the quotation.
How should I set acceptance criteria?
Before payment, agree the product, strength, lot, documents, dispatch window and any independent tests, methods and acceptance limits. Record the quality-claim process in writing.
What if the trial has a problem?
Pause any larger order, retain the material and packaging, document the discrepancy and contact us under the agreed quality-claim terms. Confirmed quality issues are replaced or refunded under our quality policy.
Does a successful trial approve future lots?
No. Use the trial to decide whether to request a larger order. Confirm each new lot, its COA and your acceptance requirements again; one trial does not establish the results for a later lot.
