Storage, Handling & Safety

1. Storage

• Store in a cool, dry place away from direct sunlight.
• Keep in a sealed, non-reactive container to prevent evaporation.
• Avoid exposure to strong magnetic fields during storage.

2. Handling

• Use protective gloves to avoid staining.
• Handle with care to prevent spills, as ferrofluid can stain surfaces.
• Avoid exposure to extreme temperatures to maintain stability.

3. Safety

• Non-toxic but should not be ingested or inhaled.
• Avoid contact with eyes and skin; wash with soap and water if exposed.
• Keep away from sensitive electronics and credit cards due to strong magnetic properties.
