Packaging & Desiccant
What it is
Sealing finished devices in foil pouches with desiccant to protect against humidity, then labeling and boxing.
How it works
Devices are pouched with desiccant, labeled with lot number and expiry, and packed into kits.
Why it matters
Humidity is the main environmental threat to lateral-flow stability; desiccant and sealed pouches extend shelf life.
Key components
- Foil pouch sealing
- Desiccant
- Lot and expiry labeling
Applications

- Poor sealing compromises stability
Common failure modes
- Humidity ingress through a poor seal
- Desiccant saturation over storage
- Labeling errors (lot / expiry)
Frequently Asked Questions
Why is desiccant used? It absorbs residual moisture to protect reagent stability and extend shelf life.
