[All-postdocs] Looking for density marker beads

[Clarissa Karthauser]

Dear fellow postdocs,
does anybody use marker beads such as these, or sinking spheres that I could use to calibrate a particle sinking velocity setup?

I only need 2-3 of each density, or alternatively the larger sinking spheres, which I could return to you after use.
I would be happy not to buy the whole package if anyone is willing to share beads or lend me spheres for a cruise in August.
Cheers,
Clarissa
