When a lab receives a request to "test this vial of peptide for me," it still has to ask many follow-up questions. Writing down the material's identity, the question to be answered, and the reporting requirements in advance reduces back-and-forth confirmation and makes it easier to judge whether the results returned actually answer the original question.
Section 1: Give the sample an identity that cannot be confused
Fill in the client's sample number, full product name, actual form, lot number, quantity submitted, and container. If you prepared a solution yourself, also write the preparation number, solvent, volume, and the basis for calculating the concentration. For information you do not have, you may write "unknown, to be confirmed"; do not guess a value just to make the form look complete. If the sequence, termini, and modifications are in a separate file, note the file name and version.
Section 2: State the decision to be made in one sentence
For example: "Plan to verify material identity and understand the area-purity basis stated in the report" is more specific than just writing "quality testing." The testing items and methods need to be confirmed by the testing provider; do not put the conclusion you hope to get into the results field. Names such as BPC-157 and LL-37 can serve as a starting point, but they cannot replace a description of the full structure and the current state of this sample.
The four groups of information most worth writing clearly on a submission form
- Sample identity: Number, full name, form, batch, and quantity
- Testing purpose: What decision it is meant to support, rather than a pre-filled "pass" conclusion
- Reporting and sample arrangements: Method, units, record scope, consumption, and leftover sample
- Confirmation and contact: Abnormal-case contact, desired timing, testing provider's confirmed version
Section 3: Distinguish required records from optional items
You can ask whether the full chromatogram, spectra, integration, or results table will be provided, as well as the method name, result units, and calculation basis. Which records can be provided and which are limited by the method or the scope of the request should be agreed in advance. If a pass/fail determination is needed, state the standard and version on which it is based; for exploratory measurements with no suitable limit, you can first agree that results and method scope will be reported truthfully, but you cannot automatically require the lab to stamp "pass."

Section 4: Arrange sample consumption and abnormal-case contacts
State the amount allowed to be consumed, whether leftover sample needs to be reserved, any pre-testing handling requirements, whether preparation solutions can be shared, and whom to contact if the method is not applicable or the sample is insufficient. Whether and how to retest should also be discussed in advance. For timing requirements, you can write a desired date and ask the lab to confirm it; do not treat a date not accepted by the testing provider as a committed turnaround time.
Look at one way to fill it in; do not copy fake information
For a teaching sample number, you can write DEMO-01; for the product, write "LL-37, see Attachment A for the specific form"; for the question to be answered, write "confirm that the identity information matches this submission." If the lot number is unknown, leave it as unknown; use actual records for quantity and concentration, and do not fill in the template's fictitious values. The template is only a communication tool; the lab's own request procedures, accreditation scope, and sample acceptance requirements should still be checked.
After downloading, keep both a blank version and a final confirmed version
This page includes a downloadable blank CSV form and a completed version clearly marked "teaching example." It is recommended to keep the final confirmed version, email confirmations, sample number photos, and reports in the same project record. The form does not automatically create a testing contract, nor does it prove that a service is provided by NHD. When inquiring about materials, you can use the relevant product entry point to explain the actual specifications and documents needed, and then confirm submission details with the testing provider.
