I am building a pipette that will suck and draw air through the same port . The valves in these devices have two push buttons and three ports
and is connected to a diaphragm pump which takes air in one direction and blows it out of the other.
When the top push button is pressed, the pump is activated and the valve has air go from the inlet of the pump to the top port to create a vacuum. When the bottom button is pressed, the path is from the outlet of the pump to the top port. Is anything like this available commercially for cheap?
I have linked an exact version of this:
https://www.pipettesupplies.com/product/s1-pipet-filler-valve-trigger-assembly/
Also a patent pertaining to the valve assembly:
https://patents.google.com/patent/U...W.+Kenney&oq=inventor:(James+W.+Kenney)+valve
Any help is appreciated thanks!
