Planning peptide inventory for a research project

Work out the total

Multiply the amount per experiment by the number of experiments, then add a margin for repeats and losses. Express the total in mg of net peptide, not nominal powder.

Convert nominal to net

If the CoA gives net peptide content, divide the required mg by that fraction to find how much powder to order. The stock solution calculator handles the content adjustment.

Choose vial sizes

The cost planner finds the cheapest combination of Nordapep vials for a target quantity. Fewer, larger vials usually cost less per mg, but each opened vial begins to age, so match vial size to how quickly it will be used.

One batch per study where possible

Batch-to-batch variation is a confounder. Ordering the full requirement from one batch keeps materials consistent across an experiment.

Track what you hold

Record compound, batch, date received, quantity and storage location for every vial in the batch log, and keep the CoA reference with it.

• Export the log to CSV for lab records.
• Re-check storage conditions against the supplier's instructions.
