Quality control & troubleshooting

• If results vary widely, check aeration rate, sample temperature, and mechanical stirrer speed for consistency.
• Ensure defoamer is properly dispersed—some require pre-emulsifying or heating.
• Watch for surfactant contamination from detergents; use solvent-rinsed glassware.
