<div dir="ltr">Hi all,<div><br></div><div>I'm a graduate student in pollination biology and as part of my PhD dissertation I am trying to identify pollen grains on insects' bodies. I've collected a number of pollinators over the years that were stored in glass vials in 70% ethanol until they were pinned. Now I am trying to extract the pollen that was left behind in the ethanol when the insects were removed. Does anyone have any suggestions for how to do that efficiently? I've tried to simply let the ethanol evaporate from the vials, but that takes a very long time. I've also tried centrifuging the solution, which works great. However, because of the large volume of ethanol in each vial, I need to transfer it to at least 7-8 microcentrifuge tubes, which is also not very efficient considering how many total samples I have. If anyone has any other methods or tips for getting the pollen out of the ethanol solution, I would greatly appreciate it!</div>
