@Felthry maybe it’s the blue color of the fluid, but my first thought was “this would be perfect for putting gel loading dye in”

@windyorigami What's gel loading dye? Searching that gives some stuff selling it (some calling it "DNA gel loading dye") but nothing saying what it is

@Felthry in gel electrophoresis, loading dye is a colored fluid that is added to the wells in the agar gel, that helps with loadingthe DNA sample, as well as provide a visual aid for how far the samples have traveled through the gel

@windyorigami oh that makes sense!

electrophoresis is a good word
