Collecting algae samples is simple and straightforward. For phytoplankton (whole water) samples, simply fill the bottles that contain Lugol’s iodine preservative, taking care not to rinse out the preservative. For periphyton samples, scrape a known area of substrate and transfer to the bottles. Please provide the area sampled.
Once water samples are preserved in Lugol’s, they are stable at room temperature and have a holding time over one year.
I recommend a Chain of Custody form when you send samples. Click here to download a pdf of this form.
Send samples to Aquatic Analysts, at your convenience, using simple containers – no coolers or ice are needed.
