What the term denotes
Nasal spray describes a delivery format: material in solution, packaged with a pump or atomiser that produces a spray. As a catalog heading it says how something is presented and nothing about its intended purpose.
Format is not purpose
A delivery format describes packaging and physical presentation. It carries no information about what a material is, what it does, or what it is for, and should not be read as implying any of those.
Research use only
Everything grouped under this heading in our catalog is designated research use only. That designation marks material as intended for laboratory research and explicitly not for diagnostic or therapeutic use. It describes intended use — it is not a statement about quality, and it does not create a category of permitted use in people.
Documentation to expect
A certificate of analysis for the lot, stated concentration, container and closure details, and storage conditions. Solutions are more sensitive to storage conditions than dry material, so the supplier's stated conditions matter more here.
Records worth keeping
Lot, date received, condition on arrival, storage location and expiry. For anything in solution, the date a container was first opened is worth recording too — an opened container is a different item from a sealed one.

Frequently asked questions
- Does the nasal spray heading say what a product is for?
- No. It describes the delivery format — material in solution with a spray applicator. It carries no information about purpose or intended use.
- What does research use only mean for a nasal spray format?
- The same as for any other format: the material is designated for laboratory research and not for diagnostic or therapeutic use. The designation is independent of packaging.
- Why does storage matter more for solutions?
- Material in solution is generally more sensitive to temperature and light than dry material, so the supplier's stated storage conditions carry more weight and an opened container should be recorded as distinct from a sealed one.
