INTRODUCTION
Sealed, silanized autosampler vials can be stored indefinitely under proper conditions, with no practical shelf-life limitations. The silanized surface remains stable and effective as long as the packaging remains unopened and intact.Once Opened: Handle with Care
After opening, the silanized surface becomes susceptible to particle adsorption, especially from:
- Cardboard fibers (from packaging materials)
- Airborne dust or contaminants
These particles can adhere to the treated surface, potentially compromising the vial’s performance—particularly in trace-level or sensitive analyses.
Best Practices for Storage and Handling:
- Keep vials sealed in their original packaging until use.
- Avoid cardboard storage after opening—use clean, inert containers instead.
- Store in a clean, dry environment, away from direct sunlight and chemical vapors.
- Use gloves or forceps when handling to avoid contamination.
- Follow FIFO (First-In, First-Out) inventory practices to minimize exposure time.
