Hello Jatin,

If water solubility is low, place your stuff in centrifuge tubes, add
water, mix well with a glass stick, long spatula or whatever does it,
centrifuge for a few minutes, and separate the water layer. If the water is
lighter, just decant or if heavier use a Pasteur pipette, and repeat the
proceedings until you washed enough.

Good luck

Jacob
