FAQ
Q: Can these replace sodium foil in experiments?
A: Yes! Thicker discs (≥0.8mm) reduce risk of short-circuiting vs. thin foils.
Q: Do you provide MSDS and compliance documents?
A: Yes, Material Safety Data Sheet (MSDS) and UN certification available upon request.
Q: How to minimize oxidation during use?
A: We recommend:
-
Transfer directly in glove box.
-
Use within 1 hour of unpacking.
-
Store unused discs in sealed argon vials.
