Research Material Receiving Procedures

The point of receipt is when a research material passes from the supplier into the laboratory’s custody and records. A systematic receiving procedure confirms the identity and condition of what has arrived, creates the starting record for the material’s time in the laboratory, and ensures that any problems with the delivery are identified and documented before the material enters stock. This overview describes general receiving practices in factual terms; it does not include guidance on using any material once received.

Outer packaging condition

The first step on receiving a package is to inspect the outer packaging before opening it. Signs of damage such as crushing, wetting, or visible breach of the outer container should be noted, since these may indicate that the contents have been exposed to adverse conditions in transit. Where damage is evident, recording its nature before opening the package creates a clear account of the condition on arrival.

Temperature indicators and cold chain

Where materials are shipped with temperature control, the package may include a temperature indicator or logger. Reviewing this indicator confirms whether the package was maintained within the required temperature range throughout transit. A temperature excursion indicator that has been triggered should be recorded and assessed. For background on what temperature excursions are and how they are managed, see Temperature Excursion Management.

Once the outer packaging is opened, the vials or containers holding the material are inspected. The inspection covers the integrity of the vial and its seal, the appearance of the label, and the visible condition of the contents. For a description of what integrity checks involve and what to look for, see Packaging Integrity Verification Methods. A vial with a damaged seal or compromised contents should be set aside and documented rather than placed into stock.

Matching material to order

Each received item is checked against the order or purchase record to confirm that the correct material and quantity have been supplied. The material name on the label is compared against the ordered item, and the quantity of vials or units is counted against the quantity ordered. Discrepancies in either are noted and followed up with the supplier.

Batch number verification

The batch number on the label is recorded and compared against the batch number on any accompanying documentation such as the certificate of analysis. Confirming that the batch numbers match ensures that the documentation relates to the specific material supplied. For guidance on what batch numbers represent and how to use them, see Research Material Batch Identification.

The receiving record captures the key information from the inspection: date received, material name, batch number, quantity, supplier, delivery condition, result of integrity inspection, and whether the material matches the order. Where a certificate of analysis or other documentation accompanies the delivery, this is noted and filed alongside the receipt record. Recording receipt contemporaneously, at the point of opening the package rather than later, ensures the accuracy of the condition assessment.

Once the receiving record is complete and the material is confirmed as acceptable, it is transferred immediately to the appropriate storage condition specified on its label. Delaying this transfer, for example by leaving material at room temperature while completing paperwork, is an avoidable source of temperature and moisture exposure. Having the storage location prepared in advance, so that material can be moved directly on receipt, is a simple practice that reduces unnecessary exposure. General storage guidance is given in Peptide Storage Guidelines, and the receiving process is the starting point for the documentation chain described in Laboratory Documentation Best Practices. Receipt also marks the beginning of the chain of custody; for how subsequent transfers of the material are formally documented, see Chain of Custody in Research Environments.
