Sample Packaging & Shipment
We reserve the right to charge a $50.00 lab fee (handling, logging samples in, disposal of samples, etc.) for any samples which are sent to us that have not been properly labelled or preserved.
Our Recommendation for Sample Preservation
We strongly suggest that you preserve your samples in Glutaraldehyde, 0.25% final concentration for phytoplankton samples (see below). Regardless of which preservative you choose, we find that both Lugol’s Iodine and Glutaraldehyde preserve best when the preservative is less than 6 months old. Try to plan your usage so that you use the volume you purchase or make within 6 months. If you are holding samples for the season, please keep in a cool, dark place (less than 25 oC). We have find that Lugol’s Iodine works best on freshwater samples when acidified and used at a 3-5% final concentration versus the common guidance of preserving to the “color of light tea” which generally equates to 1-2%.
Sample Preservation using Glutaraldehyde
Keep the glutaraldehyde bottle tightly closed and stored in a well-ventilated area when not in use! PhycoTech will not accept any responsibility for injuries or damage incurred due to the use, misuse, or storage of glutaraldehyde.
