I only have a microinjector available to me Femtojet eppendorf ( I am new this and have never used the instrument). I would like to create a negative pressure and aspirate spores. The idea is not to load a needle for injection but merely selectively isolate spores from a mixed batch and aspirate them out and collect the spores at the end. Looking at the manual I can see that I cannot aspirate but maybe you creative people have any ideas/suggestions. I have a pump, I was thinking of attaching a syringe filled with cotton bud to reduce the suction or maybe I can use running water with a Y-joint tubing to create negative pressure, any ideas are welcome. Many Thanks Justina
