En una patente de un fármaco antineoplásico, en la sección de reacciones de síntesis de los compuestos:

"The combined extracts were dried (Na2SO4), filtered, and concentrated. The crude was purified on silica gel as follows: silica gel (1 kg) was slurried in 9:1 hexane:ethyl acetate onto a 3L fritted funnel, silica settled under vacuum, **topped with sand**. The crude was loaded with a DCM/hexane mixture, and the compound was eluted using 1L sidearm flasks under vacuum. "
