Recommended Sample Preparation

1. Mix the original suspension thoroughly.

2. Use clean, filtered water or a compatible dispersing medium.

3. Prepare the required concentration by serial dilution.

4. Use low-particle-background containers and pipette tips.

5. Avoid contamination from dust and larger particles.

6. Confirm dispersion quality before measurement.

7. Prepare fresh diluted samples when possible.

For low-concentration measurements, use clean laboratory conditions to minimize background particles.

Handling Recommendations

• Mix thoroughly before sampling.

• Avoid vigorous shaking that creates bubbles.

• Use clean, particle-free containers.

• Protect the suspension from contamination.

• Do not allow the microspheres to dry.

• Avoid freezing and repeated freeze–thaw cycles.

• Confirm compatibility before adding salts or solvents.

• Follow the product label for storage conditions.
