Preserving Phytoplankton Samples with Lugol's for FlowCam Analysis

Aquatic samples don't always fit your schedule. This technical note shows how to preserve freshwater and marine samples with Lugol's iodine and store them at room temperature—so you can run them on FlowCam when you're ready.

What's inside:

• Step-by-step prep for Lugol's-preserved aquatic samples
• Experimental results from freshwater and marine samples stored up to 42 days
• Why Lugol's holds concentration stable while untreated samples drop off within a week
• When to use AutoImage mode—and when to reach for glutaraldehyde instead
• Practical tips on Lugol's type, dosing, and safe disposal
