Lyophilisation is another name for freeze-drying. It describes a processing method, while a product name and specification describe the material. When the word appears on a listing, keep those two kinds of information separate.
A process that removes water
In freeze-drying, a frozen product is processed under reduced pressure so that frozen water can leave through sublimation. A subsequent drying stage removes additional water. The FDA’s technical overview of lyophilisation explains the distinction between freezing, primary drying and secondary drying.
A dry format is different from a solution
A catalogue amount stated in milligrams is a mass. A solution concentration needs both mass and final volume. A dry-format label does not supply that final volume and cannot be read as an mg/mL figure.
The mass and concentration guide explains that distinction with a short arithmetic example. It does not prescribe how a particular material should be prepared.
What freeze-dried does not tell you
The processing term is not a complete product specification. It does not identify every component, establish a batch’s analytical results or guarantee a single storage period for all materials. Check the individual product information and the receiving laboratory’s own requirements.
Compare formats on the actual listing
Confirm whether the page describes a dry material, a prepared solution, a pack of containers or a mixed set of items. If a product page does not state the information your laboratory needs, ask before ordering. You can then compare the specific items in the research peptide catalogue.
