How to administer the nasal spray
The instructions below describe the standard handling technique used in laboratory and research settings. Every bottle is labelled with the exact fill volume, spray count and strength per spray for that product.
- Prepare the bottle. Keep the spray refrigerated upright at 2–8°C. Before use, let it sit at room temperature for about a minute. Do not shake — gentle swirling is enough if the liquid has settled.
- Prime the pump. Remove the cap and press the pump 2–3 times into the air until a fine mist appears. This ensures the dip tube is full and each subsequent spray delivers the correct volume.
- Position the nozzle. Blow your nose gently if needed. Tilt your head slightly forward (not back). Insert the nozzle just inside one nostril, no deeper than the first quarter of the tip. Aim the nozzle slightly outward, toward the ear, not toward the centre of the nose.
- Administer the spray. Close the opposite nostril with a finger. Press the pump firmly once while breathing in slowly and gently through the nose. Sniff only lightly — hard sniffing pulls the liquid down the throat.
- Repeat if required. If your research protocol calls for more than one spray, alternate nostrils where possible. Wait 30–60 seconds between sprays.
- Clean and store. Wipe the nozzle with a clean tissue or alcohol swab, replace the cap, and return the bottle to the fridge upright. Use within 2–4 weeks of opening.

How do I actually use the nasal spray?
Refrigerate upright, then let the bottle sit at room temperature for a minute. Prime the pump with 2–3 sprays into the air.

Repeat in the other nostril if your protocol calls for more than one spray. Wipe the nozzle and recap. Full instructions are shown on the nasal sprays page.
