Aspirator (Bug-Vac)

This is an aspirator for collecting small insects in the field, from sweep nets, etc. It is based on a design by Rose Entomology (http://www.roseentomology.com/Insect%20Aspirators.htm), which I highly recommend to any entomologist.

It works by mouth power! Suck on the vinyl tube and draw insects into a vial through the brass tube. The filter blocks insects from entering the vinyl tube (or your mouth).

I modeled this as an exercise/proof of concept/work in progress. You may notice that I have no photos of it attached to a vial, or being used in the field. That is because I neglected to size the aspirator head for any particular vial, and instead made it to fit a 7/8" rubber o-ring. You may have luck scaling the design and finding brass tubing and an o-ring to fit. Which is easier? If you find a vial that fits, let me know!

I don't currently have any plans to redesign this Thing, because it appears that Rose Entomology is back in business and selling equipment again.
