Laboratory storage: profiles and lot documents

Use the current-lot instruction

General handling is summarized on each compound profile; the storage conditions on the lot documentation take precedence. The current-lot documents are sent with the quote; if they do not state the storage conditions, ask for them in writing. Match those documents to the product code, lot identifier and stated material form before choosing the storage location. If the instruction is missing or does not clearly identify the material, request clarification. Keep the supplier’s written answer with the order record so the receiving team and laboratory have the same source.

Ask for the documents for the exact lot in your quote. A report describes only the batch it tested, so check that its lot number matches the lot you receive.

Laboratory storage and handling

The GHK-Cu, BPC-157 and NAD+ profiles contain general handling paragraphs under this heading. Read the paragraph for the actual compound rather than borrowing a condition from a neighboring catalog entry. These profiles describe protecting sealed material from moisture and light, with the temperature conditions specified for the lot as the controlling source. The notes provide a starting point for checking the documents, not a universal storage temperature or an expiry period.

• Keep the sealed vial under the conditions specified in the lot documentation.
• Let a cold vial reach room temperature before opening to limit moisture condensation, as summarized in the profiles.
• Avoid repeated freezing and thawing of laboratory stocks, and record the lot with each experiment.

Record the state and source

A statement for an unopened vial does not automatically apply to material in another container or another state. Record what the instruction actually covers, including the package state and any stated expiry or retest date. A missing date should remain a question for the document owner, not become a date calculated from receipt.

• Product name, SKU and lot identifier.
• Material form and whether the original container is sealed or opened.
• Storage instruction, source document, revision and date received.
• Assigned storage location and any observed departure from the documented conditions.

Resolve differences in writing

If the profile, label and lot documents appear inconsistent, retain each statement and identify its source. Ask NorthVerity which instruction applies to the exact lot and package state. For an observed temperature or environmental departure, record the available observations and package condition, then follow your organization’s review procedure. Do not infer the material’s condition from the parcel’s appearance alone. Keep the clarification and your receiving decision with the lot record so later work can trace what was known at the time.
