Hello Kenneth,
if you can cut the polymer films into small pieces/strips, you can succeed
to spin it just like that, without having to fill the empty space. Of
course this depends on the rotor size. I have succeeded in this ways with
4mm rotors many times. 7mm are harder to get away with and then you can
fill the void space with something benign, like KBr (dried in the over
before use).
Cheers,
Ulli
