Does Glass Beads Hurt Intracellular Organelles?

I'm interested in fractionating yeast cells, mainly vacuolar fraction and
When I break yeast cells, I generally use acid-washed glass beads
(425-600u) to disrupt cells with alternating maximum vortexing for 30s and
sitting on ice for 30s for 10-12 times. I'm afraid if this method could
break vacuolar and/or nuclear membranes in addition to plasma membranes
and cell walls.
Can I specifically remove nuclear fractions without contamination by any
relatively easy method? Can I pull out vacuolar fraction without losing
