When I was student I had a summer job with a waterworks where one of the duties was monitoring the algae in open reservoirs. I had the pleasure of using a microscope to identify the various microbiota and I had a key that showed at what density the various organisms would start to affect the flavour and bouquet of the water. The problem with the old slide and coverslip is that it would squash the bigger organisms like volvox. The frankenpipette would allow these to be seen in all their glory, and since it is has a known volume, you could estimate the density of the species easily.
What if you were to make one with the tubes rotated 90 degrees? Then they would be more out of the way during viewing and might even fit into a sample vessel.

Well this is cool. Thanks for showing how you clean it, that was my first thought.
That seems super useful! We'd love to use one :)
An odd tool indeed but seems useful.
Very cool tool.

Make the inside a tesla valve
Why?
cool
