Peptide storage on receipt: a guide for research labs

Peptide Confidential ships research peptides from Calgary, Alberta, as lyophilized powder in sealed vials, without ice. This guide covers what arrives in the parcel, how laboratories typically store sealed vials on receipt, and how to keep each vial tied to its batch record. It covers the sealed vials as they arrive, and nothing after they are opened.

How should lyophilized peptide vials be stored on receipt?

Store sealed vials as your laboratory’s own procedures require. Typical laboratory practice is refrigeration at 2–8 °C, or −20 °C for a longer hold. Parcels are not shipped on ice: within Canada, lyophilized powder is stable at ordinary shipping temperatures for the length of a domestic Xpresspost run. Keep each vial’s label on it.

What arrives in the parcel

Parcels are not shipped on ice. Within Canada, lyophilized powder is stable at ordinary shipping temperatures for the length of a domestic Xpresspost run. Every parcel includes the batch identification that matches its published lab report.

A parcel sent outside Canada travels longer than a domestic one, so plan for a longer transit. We make no representation about the condition of the goods in transit beyond what the published lab report for the lot states.

The fridge or the freezer?

On arrival, store sealed vials as your laboratory’s own procedures require. Typical laboratory practice is refrigeration at 2–8 °C, or −20 °C for a longer hold. Which of the two applies to a vial is for those procedures to decide.

Light and humidity

No page of ours states a light or humidity condition for any lot, and this guide does not add one: your laboratory’s own procedures decide them. What arrives is lyophilized powder in sealed vials. Where a laboratory’s document for a lot states a storage condition, read it there; the batch record links the document wherever it is published.

Labels and lot numbers

Keep each vial’s label on it: the label is what ties the vial to its batch. Open the code printed on the vial label. It leads to the batch record: the figures copied from the laboratory’s document, the test date, the laboratory’s name and, where it is published, a link to the document itself. The lot number on the label must match the lot number on the record. See Can I check a lab report myself?

Keeping lot records

  • Note the lot number of each vial you receive, and the order it came with. The lot number is the one link between a vial and its batch record.

  • Keep the code from the label, or the address of the batch record it opens. The record stays public after the vial has left us.

  • A withdrawn batch keeps its record and its reason, so anyone holding a vial from it can find out. Its lot number finds it on the lab reports page.

  • If the lot number on a label does not match its record, write to us with a photo of the label.

What this guide does not cover

Anything after a vial is opened. We supply laboratory reagents for in-vitro research, and we help with orders, shipping, batch records and certificates. The shipping policy says what is in the box.

Questions

Do peptide vials go in the fridge?

On arrival, sealed vials are stored as your laboratory’s own procedures require. Typical laboratory practice is refrigeration at 2–8 °C, or −20 °C for a longer hold.

Why are parcels not shipped on ice?

Lyophilized powder is stable at ordinary shipping temperatures, so parcels travel in a plain carton without ice packs. Within Canada, that holds for the length of a domestic Xpresspost run. The shipping policy says what is in the box.

Do you sell a peptide storage case?

No. We supply laboratory reagents only, as lyophilized powder in sealed vials. They are stored in your laboratory’s own refrigerator or freezer, as its procedures require.

How do I check the batch behind my vial?

Open the code printed on the vial label. It leads to the batch record: the figures copied from the laboratory’s document, the test date, the laboratory’s name and, where it is published, a link to the document itself. The lot number on the label must match the lot number on the record. See Can I check a lab report myself?

Do you advise on using these products?

No. We supply laboratory reagents, and we help with orders, shipping, batch records and certificates. We do not answer questions about use in people or animals.
