Magwiridwe antchito ndi kapangidwe kake:
Zigawo zazikulu za chotsitsacho ndi CH₂Cl₂, mafuta oyera ndi madzi ochepa. Pogwiritsa ntchito malo osiyanasiyana owira a zinthu zitatuzi, chotsitsacho chimachitika motsatizana kudzera mu njira zingapo, monga kusungunuka koyamba, kusungunuka mumlengalenga, kutulutsa mpweya wa vacuum, CH₂Cl₂ ndi kusefa mafuta oyera. Njira yotulutsira inalekanitsidwa ndikuyeretsedwa kuti ibwezeretse CH₂Cl₂ (chiyero > 99.97%) ndi mafuta oyera (chiyero > 99.97%) kuti ikwaniritse zofunikira zogwiritsidwanso ntchito pamzere wopanga ndikuchepetsa kugwiritsa ntchito zinthu zomwe zimagwiritsidwa ntchito popanga. Chepetsani mtengo wopanga filimu yolekanitsa.
