[Pollinator] Extracting pollen from ethanol

[Hilary Cox]

Asya,
The following is Dr. Geoff Cox's (HPLC expert) answer to your question:

Hi,

Given the size of pollen particles, ie greater than 6 microns, why not 
filter the ethanol through a 0.5 micron membrane filter?  These are 
available in Teflon or several other polymers.  Take a look at:

http://www.emdmillipore.com/US/en/life-science-research/chromatography-sample-preparation/filtration-products/microfiltration-membranes/FqCb.qB.7ZkAAAFBDQZlvzJE,nav?cid=BI-XX-BSP-P-GOOG-ASP0-B343-1016

There are several suppliers of such things; one of them should sell 
something that will work.  Asya should search on Google for 0.45 micron 
filters.  The critical thing is to be able to remove the pollen from the 
filter afterwards, but that may depend on what they want to do with them 
after.

Geoff.

  I hope this is helpful.
Hilary Cox
